Before Installation: Requirements and Planning

Section page Page 9 Installation

Before Installation: Requirements and Planning

Read these installation instructions before you install the washer or move it to a new location. The manual gives this installation sequence:

1. Choosing the proper location 2. Unpacking and removing shipping material 3. Connecting the inlet hoses 4. Connecting the drain hose 5. Leveling the washer 6. Final installation check

What you need before starting

The manual lists these tools: - Pliers - Flat-blade screwdriver - Level

The washer must be moved or installed by two or more people. This is a safety requirement.

Location requirements

Choose a place that meets these conditions: - Leave enough space between the washer and the walls for installation. - Keep the washer in a place that is not exposed to freezing temperatures or outdoor weather. - Do not block the large opening on the bottom of the washer with carpeting or other materials. The washer needs this opening for proper airflow.

Floor requirements

The floor should be: - Clean, dry, and free of dust, dirt, water, and oil - Solid and rigid, so the leveling feet cannot slide easily - Level and firm enough to support the washer without flexing or bouncing

The manual says: - A concrete floor is best. - A wood floor is acceptable if it is built to FHA standards. - The floor under the washer must not slope more than 1 inch (2.5 cm) from front to back or side to side. - Do not install the washer on carpeting or soft tile surfaces. - Never install it on a platform or weakly supported structure.

If the floor has too much flex, reinforce it to make it more rigid. If the floor is not solid, it may cause severe vibration and noise.

If you use a drain pan, follow the instructions that come with the pan carefully. Also make sure the leveling feet are adjusted for firm and even contact with the pan. If the washer is not properly leveled with a drain pan, vibration and noise can increase during operation.

Clearance requirements

For water inlet hoses, the drain hose, and airflow, allow at least: - 1 inch (2.5 cm) at the sides - 4 inches (10 cm) behind the washer

Also allow for wall, door, or floor moldings, since they may require more space.

Power outlet requirements

The washer’s power outlet must meet these conditions: - Be within 60 inches (1.5 m) of either side of the washer - Be easy to reach after installation - Not be overloaded with more than one appliance - Be grounded according to current electrical wiring codes and regulations - Use a time-delay fuse or circuit breaker

The owner is responsible for having a proper outlet installed by a qualified electrician.

Important electrical safety points from the manual: - Use a grounded 3-prong outlet. - Do not remove the ground prong from the power cord. - Do not use an adapter or extension cord.

Grounding and service safety

The washer must be properly grounded to conform with all governing codes and ordinances. The manual warns that failure to do so can cause serious injury, fire, electric shock, or death.

The manual also notes that certain internal parts are intentionally not grounded and may present a risk of electric shock during servicing only. Service personnel should not contact the pump, valve, motor, or control board while the appliance is energized.

Before you begin moving the washer

Plan the installation area before you move the appliance into place. Make sure: - Two or more people are available to move or install it - The outlet and plug will still be accessible - The washer will have the required side and rear clearance - The floor is solid, level, and clean - The location is indoors and protected from freezing and outdoor weather

Following these requirements before installation helps reduce vibration, noise, and installation problems.

Unpack and Remove Shipping Materials

Section page Page 11 Installation

Unpack and Remove Shipping Materials

Before you operate the washer, remove all shipping materials so the unit can work properly and to help prevent damage.

What to do first - Remove the carton and all shipping material. - Lift the washer off the foam base. - Inspect the washer for shipping damage as you unpack it.

Important caution about the foam base - Make sure the plastic drum support comes off with the foam base and is not left stuck to the bottom of the washer. - If you must lay the washer down to remove the carton base, protect the side of the washer and lay it carefully on its side only. - Do not lay the washer on its front or back.

Remove the shipping bolts The washer has 4 shipping bolt assemblies that must be fully removed before use.

1. Start with the bottom two shipping bolts. 2. Use the included wrench to fully loosen all 4 shipping bolts by turning them counterclockwise. 3. Remove each bolt assembly by wiggling it slightly while pulling it out.

A bolt assembly includes all of these parts: - metal bolt and washer - rubber damper - plastic rod

Replace the hole caps - Find the hole caps included in the accessory pack or attached to the back of the washer. - Install the caps in the holes left by the bolt assemblies.

Save the shipping bolts - Keep the bolt assemblies for future use. - If the washer needs to be moved again, reinstall the shipping bolts before transporting it. - Do not transport the washer without reinstalling the shipping bolts.

Helpful notes - All 4 bolt assemblies must be completely removed to avoid product damage. - Failure to remove the shipping materials can cause excessive noise and vibration. - The power cord is secured to the back of the washer with a shipping bolt to help prevent operation with the shipping bolts still in place. - If reinstalling the bolt assemblies for shipping, install the 2 short ones at the top, the long one without a hook at the bottom left, and the long one with a hook at the bottom right.

If you are stacking the washer or using a pedestal - The washer can be stacked under a dryer or placed on a pedestal or pedestal washer. - Refer to the instructions packaged with the optional pedestal kit before stacking the appliance on a pedestal. - Do not use a drain pan with a pedestal or pedestal washer installation, because it can block the drawer. - Using a drain pan may also increase vibration and noise during operation.

Why this step matters Removing all shipping materials helps the washer operate properly. Leaving shipping bolts or retainers in place can cause severe vibration and noise and may lead to permanent damage to the washer.

Before moving on Once the washer is unpacked, the shipping bolts are removed, and the hole caps are installed, you can continue with the rest of the installation process.

Connect and Secure the Drain Hose

Section page Page 14 Installation

Connect and Secure the Drain Hose

Choose the drain setup that matches your home, then secure the hose exactly as shown. The washer uses a drain hose with an elbow bracket and a provided tie strap.

Before you start

  • Make sure the drain hose is positioned correctly for your setup.
  • Keep the end of the drain hose within the allowed distance shown in the manual.
  • If the drain hose is extended too far beyond the elbow bracket, mold or microorganisms could spread to the inside of the washer.

Drain into a standpipe

1. Insert the end of the drain hose into the standpipe. 2. Use the provided tie strap to secure the drain hose in place.

Drain into a laundry tub

1. Clip the end of the hose into the elbow bracket. 2. Connect the elbow bracket within 4 inches (10 cm) of the end of the drain hose. 3. Hang the end of the drain hose over the side of the laundry tub. 4. Use the provided tie strap to secure the drain hose in place.

Drain through a wall drain

If the water valves and drain are built into the wall:

1. Fasten the drain hose to one of the water hoses. 2. Use the provided tie strap. 3. Install the tie strap with the ribbed side on the inside.

Hose length and position limits

  • The manual shows the drain connection height range as 24–96 inches (61–244 cm).
  • Do not extend the drain hose more than 4 inches (10 cm) beyond the end of the elbow bracket.

Important caution

- If the hose extends more than 4 inches (10 cm) beyond the elbow bracket, mold or microorganisms could spread to the inside of the washer.

Related note from this page

This page also begins the leveling instructions for the washer. It notes that the drum spins at very high speeds and that the washer must be on a solid, level surface to minimize vibration, noise, and unwanted movement. Using the washer without leveling it may cause excess vibration and noise, leading to malfunction. Adjust the leveling feet only as far as necessary, since extending them more than necessary can also cause vibration.

Level the Washer

Section page Page 15 Installation

Level the Washer

Before you begin, make sure the floor where the washer will sit is clean, dry, and free of dust, dirt, water, and oil. This helps keep the washer feet from sliding. If the feet can move or slide, the washer may vibrate more and make more noise.

What to do

1) Put the washer in its final location Move the washer to the exact place where it will be used.

Be careful not to pinch, strain, or crush the water hoses and drain hose while positioning the washer.

If you have a carpenter’s level, you can use it to check whether the washer is level. The slope under the washer should not exceed 1 inch, and all 4 leveling feet must rest firmly on the floor.

2) Adjust the leveling feet Turn all 4 leveling feet: - one direction to raise the washer - the other direction to lower the washer

Keep adjusting until the washer sits level and all 4 feet are firmly on the floor.

3) Tighten the locknuts When the washer is level, turn the locknuts counterclockwise and tighten them.

4) Check the washer again Push or rock the top edges of the washer gently. - If the washer does not rock, the level is correct. - If the washer rocks, adjust the leveling feet again.

If the floor is slippery If the washer is installed on a slippery surface, it may move because of excessive vibration. Incorrect leveling can also cause noise, vibration, and malfunction.

If this happens, the manual says to install non-skid pads under the leveling feet and then adjust the level.

Using non-skid pads 1. Clean the floor where the pads will be attached. - Use a dry rag to remove foreign objects or moisture. - If moisture remains, the pads may slip.

2. After placing the washer in the installation area, adjust the level.

3. Place the adhesive side of the non-skid pad on the floor. - It is most effective to install the pads under the front leveling feet. - If that is hard to do, place them under the back leveling feet.

4. Recheck the washer’s levelness. - Push or rock the top edges of the washer gently to make sure it does not rock. - If it rocks, level the washer again.

Quick check A properly leveled washer should: - sit firmly on all 4 feet - not rock when you gently push the top edges - have the locknuts tightened after leveling - stay in place without sliding during use

FAQs

How do I know the washer is level? Gently push or rock the top edges of the washer. If it does not rock, the washer is level enough for this procedure.

What if the washer rocks after I level it? Readjust the leveling feet and check it again. If needed, recheck the washer’s levelness after placing non-skid pads.

Can I install the washer on a slippery floor? Yes, but the manual says it may move because of excessive vibration. If that happens, install non-skid pads under the leveling feet.

Where should non-skid pads go? They are most effective under the front leveling feet. If that is hard to do, place them under the back leveling feet.

Why should the floor be clean and dry? Because dirt, water, oil, or other moisture can let the washer feet slide more easily, which can increase vibration and noise.

What to check during the test Make sure: - Water is supplied properly. - The washer does not rock or vibrate excessively. - The washer drains well during the spin cycle.

If something is not right The manual gives these checks if the test does not go as expected: - If water leaks during water supply, see Connecting the Water Inlet Hoses to connect them properly. - If the washer rocks and vibrates excessively, see Leveling the Washer and level it again. - If the drain does not work, see Connecting the Drain Hose and install the hose properly.

Power cord and outlet safety reminders These points are part of the final installation check and power connection: - Do not use a worn or damaged power cord or power plug. Replace or repair it immediately. - Do not modify the power cord or plug provided with the appliance. - Do not damage the cord when installing or moving the washer. - Make sure the appliance is grounded. - Connect it only to a grounded outlet conforming to the rating. - Do not damage or cut off the ground prong. - Do not use an adapter or extension cord. - For best performance, plug the washer into its own individual outlet to help avoid overloading house wiring. - If an extension cord is necessary, use only a new, UL-listed cord with a 3-prong grounding plug rated at no less than the branch circuit, and do not use one longer than 3 feet.

When to stop and get help If you are unsure whether the appliance is properly grounded, check with a qualified electrician or service technician. If the plug does not fit the outlet, have a proper outlet installed by a qualified electrician.

Final result If the test cycle runs normally and you confirm that the washer fills, spins, drains, and stays stable, the installation is complete.

Before Use: Basic Operation Overview

Important safety note Before operating the washer, read the Safety Instructions to reduce the risk of fire, electric shock, or injury.

Before the first wash Before washing clothes for the first time: - Select the Normal cycle. - Add half the usual amount of detergent. - Start the washer without clothes.

This first run helps remove possible residue and water that may have been left in the drum during manufacturing.

Basic wash sequence

1) Sort laundry and load the washer For better washing results and less chance of damage: - Sort laundry by fabric type, soil level, color, and load size as needed. - Open the door and load the items into the washer.

If you are using single-use detergent packs, or gel or tablet detergents, place them in the drum before loading the laundry.

2) Add cleaning products - Add the proper amount of HE (High-Efficiency) detergent to the detergent dispenser. - If desired, add bleach or fabric softener to the appropriate areas of the dispenser drawer. - Do not place liquid or powdered detergent packs, or gel or tablet detergents, in the dispenser.

3) Turn on the washer Press the Power button to turn on the washer.

4) Select a cycle Choose a cycle by: - Turning the cycle selector knob, or - Pressing the cycle buttons repeatedly until the desired cycle is selected.

The washer shows the preset wash temperature, spin speed, soil level, and option settings for that cycle.

Notes about cycles: - The Normal cycle must be selected in order to change its default settings. - If you press Start/Pause without selecting a cycle, the washer immediately starts the Normal cycle with the default settings.

5) Adjust settings If desired, change the default settings using the cycle modifier and option buttons.

Keep in mind: - Not all modifiers and options are available on all cycles. - If a selection is not allowed, a different chime sounds and the LED does not light up.

6) Begin the cycle Press Start/Pause to begin.

What happens next: - The door locks. - The washer agitates briefly without water to measure the weight of the load.

If Start/Pause is not pressed within a certain time, the washer shuts off and all settings are lost.

What to expect during washing The washer moves laundry in a way that uses less water while still fully saturating the clothing. Because of this, it is normal if you cannot see water during the wash cycle.

End of cycle When the cycle is finished: - A melody sounds. - Remove the clothing right away to reduce wrinkling. - Check around the door seal when removing the load, because small items may be caught there.

If the door will not unlock If the temperature or water level inside the machine is too high, the door will not unlock when Start/Pause is pressed, and the Add Item function will not be available on applicable models.

To stop a cycle and drain the water completely: - Turn the power off. - Turn it on again. - Select Rinse+Spin.

How to sort laundry Sorting similar items helps improve wash results and reduce damage.

Sort by color - Wash dark clothes separately from light colors or whites. - Mixing dark and light items can cause dye transfer or discoloration.

Sort by soil level - Wash heavily soiled clothing together. - Washing lightly soiled clothing with heavily soiled clothing can reduce wash performance for the lightly soiled items.

Sort by fabric type - Do not mix delicate articles with heavy or sturdy fabrics. - Mixing them can reduce wash performance and may damage delicate items.

Sort by lint type Some fabrics attract lint and others give it off. - Do not mix lint collectors and lint producers in the same load. - Mixing them can cause pilling and linting.

Example: - Lint collector: knit sweater - Lint producer: terry cloth towels

Quick reminders - Use the correct amount of HE detergent. - Put detergent packs, gel, or tablet detergents in the drum, not in the dispenser. - If you start a cycle without choosing one, the washer uses Normal with default settings. - Remove laundry promptly at the end of the cycle.

Sorting and Loading Laundry

Section page Page 19 Operation

Sorting and Loading Laundry

Follow these steps before starting a wash cycle so clothes clean well and the washer stays balanced.

1) Check the care label on each item Many garments have a fabric care label. Use the label instructions to help choose the right cycle and options.

The manual lists these label directions: - Hand wash - Machine wash, Normal cycle - Gentle/Delicate setting — slow agitation and/or reduced wash time - Perm Press/Wrinkle Resistant setting — includes a cool down or cold spray before a slower spin - Water temperature: Hot, Warm, or Cold/Cool - Do not wash - Do not wring - Bleach symbols: Do not bleach, Any bleach when needed, or Only non-chlorine bleach when needed

2) Prepare garments before loading For best results, sort and prepare items before they go into the drum.

General tips from the manual: - Check and empty pockets. Paper clips, coins, matches, and other items can damage clothing and the washer. - Close zippers and hooks, and tie drawstrings to prevent snagging or tangling. - Pretreat heavily stained areas for best results. - Brush off heavy soil, dust, and hair before washing. Excess dirt or sand can abrade other fabrics and reduce wash performance.

3) Load the drum correctly Load clothes loosely so they have room to circulate. - Do not press down on items while stacking them in the drum. - Do not overfill the drum. - The door must close easily. - The washer can be fully loaded, but the drum should not be tightly packed.

A few loading guidelines help prevent imbalance: - Combine large and small items in the drum. - Load large items first. - Large items should not be more than half of the total load. - The washer will not fill or operate with the door open.

4) Handle bulky, small, and delicate items carefully Bulky items - Wash thick, bulky items individually. - Heavy blankets, comforters, bedspreads, or pet beds can tangle or cause an unbalanced load if washed with other items.

Small items - Do not wash a single small item by itself. - Add enough similar items to prevent an out-of-balance load. - Wash small, light items in a mesh bag. - Small items can get caught in the impeller at the bottom of the drum. - Brassiere hooks can snag on other clothing or the drum.

5) Keep the door seal area clear Before closing the door: - Make sure all clothes and items are inside the tub. - Do not let anything hang over the rubber door seal. - Check for and remove any small items caught under the door gasket.

If clothing gets caught when the door is closed, it may be damaged and may damage the door seal.

6) Special caution for waterproof and water-resistant items Clothing or articles that are waterproof or water-resistant must be washed only in these cycles: - Waterproof - Bedding - Bulky/Large - Jumbo Wash

Examples given in the manual include water-resistant clothing, mattress covers, outdoor clothes, and plastic mats.

Do not wash these items in other cycles. The manual warns that doing so may cause abnormal vibration and may damage the washer, clothes, walls, floor, and surrounding objects. It may also cause personal injury.

7) About detergent use This washer is designed for HE (High-Efficiency) detergents only. - HE detergents produce fewer suds and dissolve more efficiently. - They help improve washing and rinsing performance and help keep the inside of the washer clean. - Using detergent that is not HE may cause oversudsing, unsatisfactory performance, error codes, cycle failure, and washer damage. - Detergents labeled HE-compatible may not provide optimal results. - Always measure detergent using the dispenser or measuring device provided by the detergent manufacturer. - For an average load, use less than half of the recommended amount.

Following these loading and sorting steps helps the washer clean effectively and reduces the chance of damage or imbalance.

Using Detergent, Bleach, and Other Laundry Products

Section page Page 21 Operation

Using Detergent, Bleach, and Other Laundry Products

This washer uses an automatic dispenser drawer for many laundry products, but some products must go directly into the drum. For best results, use the correct compartment and do not overfill.

Before you add anything - Always use HE (High-Efficiency) detergent with this washer. - Follow the detergent, bleach, and softener manufacturer’s recommendations. - Use less detergent for soft water, light soil, or smaller loads. - Be extra careful with 2X and 3X concentrated detergents. Even a small extra amount can cause problems. - Never use more than the maximum amount recommended by the manufacturer. - Do not place or store detergent, bleach, or liquid fabric softener on top of the washer. These products can damage the finish and controls.

Single-use detergent packs, gel, and tablet detergents - Place liquid or powdered detergent packs, gel detergents, or tablet detergents directly in the drum before adding laundry. - Do not put these products in the dispenser drawer. - Do not use more than one single-use detergent pack in the washer. - If detergent residue remains on fabrics, reduce the detergent amount or select Extra Rinse.

Using the dispenser drawer 1. Open the dispenser drawer. 2. Add products to the correct compartment. 3. Gently close the drawer before starting the cycle.

Important cautions: - Slamming the drawer may cause detergent to overflow into another compartment or be dispensed into the drum too early. - Be careful not to catch your hand in the drawer while closing. - A small amount of water left in the dispenser compartments at the end of the cycle is normal.

Pre-wash detergent compartment Use this compartment only when using the Pre-wash option. - Add liquid or powdered detergent here. - Use half the amount recommended for the main wash cycle. - Example: if the main wash needs one measure, add 1/2 measure for pre-wash. - If you use pre-wash, liquid detergent for the main wash must be loaded into the liquid detergent cup accessory in the main wash dispenser, where applicable, so it is not dispensed with the pre-wash detergent.

Main wash detergent compartment This compartment holds detergent for the main wash cycle. - You may use powdered or liquid detergent here. - The detergent is added at the beginning of the cycle. - Do not exceed the maximum fill line. - Too much detergent can cause buildup in clothing and in the washer. - Liquid or powdered color-safe bleach may be added to the main wash compartment with detergent of the same type. - Do not mix liquids and powders.

If your dispenser includes a liquid detergent cup and insert: - Leave them in place when using liquid detergent. - Remove them when using powdered detergent. Powdered detergent will not dispense properly if the cup and insert are left in place. - The liquid detergent cup has guidelines showing how much liquid detergent to add.

Bleach use Liquid chlorine bleach compartment - This compartment is for liquid chlorine bleach only. - The bleach is dispensed automatically at the proper time during the wash cycle. - The dispenser is activated twice to help ensure the bleach is fully dispensed. - Any liquid left in the dispenser at the end of the cycle is water, not bleach.

Bleach safety and limits: - Follow the bleach manufacturer’s recommendations. - Never add more than one cup. - Do not exceed the maximum fill line. - Too much bleach may be dispensed immediately and can damage fabrics. - Never pour undiluted liquid chlorine bleach directly onto the load or into the drum. - Do not use color-safe bleach or oxygen bleach in the same cycle with liquid chlorine bleach. - Do not mix chlorine bleach with ammonia or acids such as vinegar or rust/scale remover; this can produce a lethal gas. - Do not add powdered bleach to the liquid bleach compartment. - Powdered or liquid color-safe bleach will not dispense properly in this compartment.

Main wash compartment and bleach - Liquid or powdered color-safe bleach may be added to the main wash compartment with detergent of the same type. - Do not mix liquids and powders.

Fabric softener compartment This compartment holds fabric softener for automatic dispensing during the final rinse cycle. - You may use powdered or liquid fabric softener. - Do not exceed the maximum fill line. - Too much fabric softener may stain clothes or cause buildup on fabrics or in the washer. - Dilute concentrated fabric softeners with warm water. - Never pour fabric softener directly onto the load or into the drum. - If you use a detergent that does not dissolve easily or is very thick, it may leave residue and clog the dispenser.

Quick placement guide - Pre-wash compartment: detergent for Pre-wash only. - Main wash compartment: detergent for the main wash; may also accept color-safe bleach of the same type. - Fabric softener compartment: fabric softener only. - Liquid chlorine bleach compartment: liquid chlorine bleach only. - Drum: single-use detergent packs, gel detergents, and tablet detergents.

Practical reminders - Use less detergent for smaller or lightly soiled loads. - Measure carefully, especially with concentrated detergents. - Keep products within their fill lines. - Close the dispenser drawer gently. - If detergent residue remains on fabrics, reduce detergent or use Extra Rinse.

Section page Page 37 Maintenance

Cleaning the Washer Exterior and Door

Keeping the outside of the washer and the door clean helps protect the finish and reduce moisture and odor.

Safety first - Unplug the appliance before cleaning to avoid the risk of electric shock. - Do not spray water inside the washer. This may cause fire or electric shock. - Do not use volatile substances such as benzene, paint thinner, alcohol, or acetone, and do not use abrasive cleaners or detergents with strong chemical components. These can discolor or damage the appliance, or may cause a fire. - Do not touch the surface or the display with sharp objects.

After each wash When a cycle is finished: - Wipe the door and the inside of the door seal to remove moisture. - Wipe the body of the washer with a dry cloth to remove moisture. - Leave the door open so the drum interior can dry. - Remove items from the washer as soon as the cycle is complete. Leaving damp items inside can cause wrinkling, color transfer, and odor.

Cleaning the exterior and door For regular cleaning: - Use a damp cloth to wipe the washer exterior. - Use a towel or soft cloth to wipe around the washer door opening and door glass. - Wash the door on the outside and inside with a damp cloth, then dry it with a soft cloth. - Immediately wipe off any spills.

Leaving the door open After you finish using the washer, leave the door open overnight to let air circulate and dry the drum. This helps prevent odors.

Cleaning the drum with Tub Clean Over time, residue can build up in the drum and lead to mildew or a musty odor.

Use the Tub Clean cycle: - monthly to remove residue and help prevent odor, - more often if the washer is used heavily or if odor is already present, - once a week for three consecutive weeks if mildew or a musty smell already exists.

Important limits: - Run Tub Clean only when the drum is empty. - Never load laundry while using this cycle. Laundry may be damaged or contaminated with cleaning products. - Do not exceed the maximum fill line when adding bleach or powdered cleaners. - Powdered cleaners may remain in the drum after cleaning.

How to run Tub Clean 1. Remove any clothing from the drum. 2. Add cleaning agents as directed below. 3. Close the door and press the Power button. 4. Select the Tub Clean cycle and press Start/Pause. 5. When the cycle ends, open the door and allow the drum interior to dry completely.

Cleaning agents for Tub Clean Use only the method that matches the cleaner you have: - Drum cleaner or lime scale remover: add to the main detergent compartment of the detergent dispenser. - Liquid chlorine bleach: add to the bleach compartment of the detergent dispenser. - Powdered cleaner: pull out the liquid detergent cup before adding it to the main detergent compartment. - Cleaning tablets: place directly into the washer drum. - For other drum cleaning products, follow the manufacturer’s instructions and recommendations.

If you use a descaler If you use a descaler or drum cleaner during Tub Clean, use the Rinse+Spin option to rinse the washer drum before running your next wash cycle.

Automatic Tub Clean reminder When the power is on and the tcL message blinks on the display, it means the washer drum needs cleaning. The reminder usually appears every one to two months, depending on how often the washer is used.

Hard water and mineral buildup In areas with hard water, mineral scale can form on internal components. Periodically clean mineral buildup to extend the washer’s lifespan. A water softener is recommended in hard-water areas. - Use a descaler to remove visible mineral buildup on the washer drum. - After descaling, always run the Tub Clean cycle before washing clothing. - Mineral scale and other spots may be removed from the stainless steel drum with a soft cloth soaked in stainless steel cleaner. - Do not use steel wool or abrasive cleaners.

Child safety during cleaning Make sure children and pets do not climb into the drum. Engage the Control Lock feature if needed to prevent children from accidentally starting a wash cycle.

Clean the Detergent Drawer and Water Inlet Filters

Section page Page 39 Maintenance

Clean the Detergent Drawer and Water Inlet Filters

This section covers two maintenance tasks that can help prevent filling problems, leaks, and buildup:

  • Cleaning residue from the detergent drawer opening
  • Cleaning the water inlet filters if the washer does not fill properly

Cleaning the detergent drawer opening

After cleaning the drawer itself, clean the drawer opening where the detergent drawer slides in.

1. Use a small, non-metal brush. 2. Clean the recess around the drawer opening. 3. Remove all residue from the upper and lower parts of the recess. 4. Replace the drawer.

Use care to remove buildup from both the top and bottom areas of the opening so the drawer can sit properly.

Cleaning the water inlet filters

The washer has inlet filter screens that protect the delicate parts of the inlet valve from particles in the water supply.

When to clean them

Clean the inlet filters if:

  • The washer does not fill properly
  • An error message appears on the display during filling
  • You use the washer in an area with hard water, because the filter may clog more often from lime buildup

Important cautions

  • Do not use the washer without the inlet filters.
  • Operating the washer with the filters removed could cause a valve to open continuously, resulting in flooding and/or property damage.
  • If the filters are missing, leaks and malfunction can occur.

How to clean the inlet filters

1. Turn off the washer and unplug the power cord. 2. Turn off the hot and cold water faucets. 3. Unscrew the hot and cold water hoses from the back of the washer. 4. Carefully remove the filters from the water valves. - Use pliers to pull out the filters from the water valves. 5. Remove any foreign objects from the filters. 6. Soak the filters in white vinegar or a lime scale remover. - If you use a lime scale remover, follow the manufacturer’s instructions. - Be careful not to damage the filters while cleaning them. 7. Rinse the filters thoroughly. 8. Press the filters back into place.

What the washer is telling you

If the washer does not fill properly, an error message will appear on the display. This can happen when the inlet valve filter screens are clogged by:

  • Hard water scale
  • Sediment in the water supply
  • Other debris

Helpful note for hard water

If you use the washer in an area with hard water, the inlet filter may clog due to lime buildup and may need more frequent cleaning.

Troubleshooting Overview and FAQs

Section page Page 43 Troubleshooting

Troubleshooting Overview

Your washer has an automatic error-monitoring system that detects and helps diagnose problems early. If the washer does not work properly or does not work at all, check the items below before calling for service.

For more detailed information or videos, LG directs you to the troubleshooting page at www.lg.com.

Common Questions and Checks

Loud banging noises while the washer is filling with water This is usually not a problem with the washer itself. It is often caused by plumbing in the home. When the washer’s water valve shuts off, it can make your home’s pipes move, creating a loud banging sound. This is called water hammer. It can be reduced by installing a water hammer arrestor. These are available at local hardware or home improvement stores.

Very little water in the washer This is normal for an HE (High-Efficiency) washer. HE washers are designed to clean clothes using a minimum amount of water and energy. Because the water level is low, the detergent becomes more concentrated, which helps cleaning performance.

Pressing a button makes the washer beep but nothing happens The Control Lock feature is on. To turn it off, turn on the washer, then press and hold the button marked Control Lock, or the button with Control Lock written on or under it, for 3 seconds.

Where to put powdered laundry products If you are using powdered laundry detergent, put it in the main detergent dispenser after removing the liquid detergent insert. Powdered laundry agents or powdered color-safe bleach should be put directly into the drum. You can place them in the empty drum before adding clothes, or on top of the laundry after loading the washer.

Error Message: IE (Inlet Error) If the washer shows IE, check the water supply and inlet hoses.

Possible causes and what to do: - Water supply faucets are not fully open. - Make sure the faucets are fully open. - Water inlet hoses are kinked, pinched, or crushed. - Make sure the hoses are not kinked, pinched, or crushed behind or under the washer. - Be careful when moving the washer during cleaning or maintenance. - Water inlet filters are clogged. - Clean the inlet filters. See the Maintenance section. - Water supply pressure to the faucet or house is too low. - Check another faucet in the house to make sure household water pressure is adequate and flow is not restricted. - Disconnect the water inlet hoses from the washer and run a few gallons of water through the hoses to flush out any dirt. - If the flow is still too low, contact a plumber to repair the water supply lines. - Water supply is connected with leak-limiting hoses. - Hoses designed to limit leaks are not recommended. - Leak-limiting hoses can trip falsely and prevent the washer from filling.

Before Calling for Service If you notice a problem, review these common checks first. In many cases, the issue is related to the water supply, hose condition, water pressure, or a washer setting such as Control Lock.

Operation Problems: Leaks, Detergent Dispensing, Filling, and Cycle Behavior

Section page Page 46 Troubleshooting

Operation Problems: Leaks, Detergent Dispensing, Filling, and Cycle Behavior

This section helps you troubleshoot common washer problems such as leaks, detergent not dispensing correctly, filling issues, pauses during a cycle, and the washer stopping or not starting.

Banging noise when the washer is filling with water

If you hear a banging noise while the washer is filling, this is described as water hammer.

  • This happens when plumbing in the home moves or flexes as the washer water valves shut off.
  • Water hammer is not caused by a defect in the washer.
  • For best results, install water hammer arrestors between the fill hose and the washer. These are sold separately at hardware or home improvement stores.
  • If household water supply pressure is very high, adjust the household water supply regulator to a lower pressure, or contact a plumber.

Water leaking

If water is leaking, check these possible causes:

Hoses are not connected correctly - Check hoses and connectors for leaks, cracks, and splits. - Tighten hose connections.

House drain pipes are clogged - The washer pumps out water very rapidly. - During drain, look for water backing up out of the drain pipe. - If water comes out of the drain pipe, check that the drain hose is installed properly and that the drain is not restricted. - Contact a plumber to repair the drain pipe.

Drain hose has come out of the drain connector or is not inserted far enough - Tie the drain hose to the inlet hose or standpipe to keep it from coming out during drain. - For smaller drain pipes, insert the drain hose as far as the drain hose flange. - For larger drain pipes, insert the drain hose 1 to 2 inches past the flange.

Oversudsing of detergent Too much suds can cause leaks.

  • Use only HE (High-Efficiency) detergent.
  • The normal amount is 1/4 to 1/2 of the maximum amount recommended by the detergent manufacturer.
  • Use less detergent for small loads, lightly soiled loads, or very soft water.
  • Never use more than the manufacturer’s maximum amount.

Excessive sudsing

If there is too much suds:

  • Use only detergent with the HE logo.
  • HE detergents are made for HE washers and contain suds-reducing agents.
  • Check detergent quantities in the Detergent Use instructions in the Operation section.
  • If sudsing or detergent residue continues, add an extra rinse.

Incomplete or no dispensing of detergent

If detergent is not dispensing properly:

Detergent compartments clogged from incorrect filling - Put detergent and additives into the correct dispenser compartments. - Always make sure the dispenser drawer is fully closed before the cycle starts.

Too much detergent used - Use the suggested amount of detergent according to the manufacturer’s recommendations. - You may dilute detergent with water to the maximum fill line on the compartment to help avoid clogging. - Use only HE detergent. - Use as little detergent as possible. Using too much detergent can cause poor wash and rinse performance and may contribute to odors in the washer.

Insufficient water supply - Make sure both hot and cold water faucets are turned on all the way.

Normal residue - A small amount of detergent remaining in the dispenser is normal. - If residue builds up, it can interfere with normal dispensing. Follow the cleaning instructions.

Washer will not turn on or operate

Power issue - Make sure the plug is securely inserted into a grounded, 3-prong, 120-VAC, 60 Hz outlet. - If a house fuse is blown, a circuit breaker has tripped, or there has been a power outage, reset the breaker or replace the fuse. - Do not increase fuse capacity. - If the problem is caused by a circuit overload, have it corrected by a qualified electrician.

Washer will not operate - If the control panel has powered off due to inactivity, press the Power button. - Make sure the washer is plugged in. - Turn both hot and cold faucets fully on. - Confirm the cycle is set correctly, close the door, and press Start/Pause. - Close the door completely and make sure nothing is caught under it. - Check house circuit breakers/fuses. The washer should be on a dedicated branch circuit. - If Start/Pause is not pressed after setting the cycle, press Power, reselect the cycle, and press Start/Pause. - If Start/Pause is not pressed within a certain time, the washer turns off. The time varies by model, from 4 to 60 minutes. - If household water pressure is extremely low, check another faucet in the house. - If the washer has been exposed to freezing temperatures for an extended time, let it warm up before pressing Power. Otherwise, the display will not come on.

Washer stops for a few minutes and then restarts

This is normal.

  • A motor protection device may activate to prevent the motor from overheating.
  • If this happens, the washer stops for a few minutes and then starts again.

Washer is not filling properly

Possible causes include:

Filter is clogged - Make sure the inlet filters on the fill valves are not clogged. - See Cleaning the Water Inlet Filters in Maintenance.

Inlet hoses may be kinked - Check that the inlet hoses are not kinked or clogged.

Energy efficiency / normal fill level - This is a High-Efficiency (HE) washer. - Water level settings may be different than a conventional washer. - The water will not normally cover the clothes. - The fill level is optimized for wash motion to achieve the best wash performance.

Insufficient water supply - Make sure both hot and cold water faucets are fully open.

Washer door is open - Close the door and make sure nothing is caught under it.

Water in the washer does not drain or drains slowly

  • Make sure the drain hose is free of clogs or kinks and is not pinched behind or under the washer.
  • If the end of the drain hose is more than 96 inches (2.4 m) above the bottom of the washer, move it lower.
  • For best performance, the end of the drain hose should be no higher than 66 inches (168 cm).

Bleach does not dispense

Bleach dispenser cover is not properly installed - On models with a cover, make sure the bleach cover is properly installed and snapped into place before the cycle begins.

Bleach dispenser is dirty or clogged - Lift out the bleach dispenser cover and clean out the reservoir. - Lint and other debris inside the dispenser may prevent proper dispensing.

Premature dispensing of bleach

  • Do not store bleach in the dispenser for future use.
  • The bleach is dispensed every load.
  • Do not overfill the bleach dispenser.
  • Overfilling will cause bleach to dispense immediately and can damage the laundry or the washer.
  • Always measure bleach.
  • Never fill above the max line on the dispenser.
  • A half cup is sufficient for most loads.
  • Never use more than 1 cup of bleach.

Wrinkling

- Remove items from the washer as soon as the cycle is complete.

Notes on cycle time

The washer may take longer than usual because it automatically adjusts wash time for the load size, water pressure, and other operating conditions.

  • This is normal.
  • The time remaining shown in the display is only an estimate.
  • Actual time may vary.

Quick checks summary

  • Use only HE detergent.
  • Use less detergent when loads are small, lightly soiled, or the water is very soft.
  • Make sure the dispenser drawer is fully closed.
  • Check hot and cold water faucets.
  • Check hoses, filters, and drain hose routing.
  • Press Power, then set the cycle again and press Start/Pause if the washer turned off.
  • A brief stop and restart can be normal when motor protection is activated.

Laundry Results Problems: Wrinkling, Staining, Odor, and Wi‑Fi Issues

Section page Page 49 Troubleshooting

Troubleshooting Laundry Results, Odors, and Wi‑Fi

Use the suggestions below when clothes are wrinkled, stained, smell musty, or when the washer will not connect to Wi‑Fi.

Wrinkling

The washer may be overloaded. - The washer can be fully loaded, but the drum should not be tightly packed. - The door should close easily.

Hot and cold water inlet hoses may be reversed. - A hot water rinse can set wrinkles in garments. - Check the inlet hose connectors.

Staining

Bleach or softener may have dispensed too soon. - The dispenser compartment may have been overfilled or closed too quickly, which can cause bleach or softener to dispense immediately. - Measure bleach carefully, and never use more than 1 cup.

Bleach or softener may have been added directly to the drum. - Always use the dispensers so laundry products are released at the correct time in the cycle.

Items may not have been unloaded promptly. - Remove clothes from the washer as soon as possible after the cycle finishes.

Clothes may not have been sorted properly. - Wash dark colors separately from light colors and whites to prevent discoloration. - Never wash heavily soiled items with lightly soiled items.

Poor stain removal

The right options may not have been selected. - Heavier soils and tougher stains may need extra cleaning power. - Select the Heavy Soil feature to boost the cleaning power of the chosen cycle.

The stains may already have been set. - Items that have already been washed may have stains that are set in. - These stains may be hard to remove and may require hand washing or pre-treating.

Musty or mildewy odor in the washer

Too much detergent, or the wrong detergent, may be used. - Use only HE (High-Efficiency) detergent, and follow the manufacturer’s instructions.

The inside of the drum may not be cleaned properly. - Run the Tub Clean cycle regularly.

Odor

Some odors are normal, especially at first. - A smell from the rubber parts of the washer is normal for new rubber and should disappear after the machine has been run a few times.

Other odors can come from parts that need cleaning or checking. - Clean the rubber door gasket and door seal regularly. - Check under the door seal for small items when unloading the washer. - Clean the drainage pump filter regularly. - Make sure the drainage hose is installed properly and is not kinked or blocked, so water does not siphon back into the washer.

Wi‑Fi: trouble connecting the appliance and smartphone

If the washer will not connect to Wi‑Fi, check the following:

  • Wi‑Fi password entered incorrectly: Delete your home Wi‑Fi network and begin the connection process again.
  • Mobile data is turned on: Turn off mobile data on your smartphone before connecting the appliance.
  • Network name (SSID) is incorrect: The wireless network name should use only English letters and numbers. Do not use special characters.
  • Router frequency is not 2.4 GHz: Only a 2.4 GHz router frequency is supported. Set the wireless router to 2.4 GHz. If needed, check with your Internet service provider or router manufacturer.
  • Appliance and router are too far apart: Move the router closer to the appliance or install a Wi‑Fi repeater.

If the app asks for a password to connect to the product on certain phones

  • Find the network name that starts with “LG” under Settings > Networks.
  • Note the last part of the network name.

Practical FAQs

Why are my clothes wrinkled after washing? The drum may be overloaded, or the hot and cold water inlet hoses may be reversed.

Why did bleach or softener stain my clothes? They may have dispensed too soon, been added directly to the drum, or been used in too much quantity.

What should I do if stains are not coming out? Select the Heavy Soil feature, and consider hand washing or pre-treating if the stains were already set.

Why does my washer smell musty? Too much or incorrect detergent, or a drum that has not been cleaned regularly, can cause odor. Run Tub Clean regularly.

Why won’t the washer connect to Wi‑Fi? Check the password, turn off mobile data, use a 2.4 GHz router, keep the appliance closer to the router, and make sure the network name uses only letters and numbers.

Limited Warranty: dispute resolution and Canada warranty terms

This section explains how disputes are handled and, for Canada, what the limited warranty covers and does not cover.

If you want to start arbitration in the U.S. Before beginning an arbitration proceeding, you must first send LG written notice at least 30 days in advance. Mail the notice to:

LG Electronics, USA, Inc. Attn: Legal Department- Arbitration 111 Sylvan Avenue Englewood Cliffs, NJ 07632

Your notice must include: - your name - your address - your telephone number - the product involved - a description of the claim - the relief you are seeking

LG and you are expected to try in good faith to resolve the claim during this 30-day period. If the dispute is not resolved, either party may file for arbitration.

Binding arbitration and class action waiver If the dispute is not resolved after the notice period, claims must be resolved by binding arbitration on an individual basis, unless you opt out as described below. The warranty says disputes between you and LG cannot be combined with disputes involving other people’s products or claims. It also says disputes may not proceed as a class or representative action.

Either party may bring an individual action in small claims court instead of arbitration, but not as a class or representative case.

Arbitration rules Either you or LG can start arbitration by making a written demand. Arbitration is handled by the American Arbitration Association (AAA) under the AAA Consumer Arbitration Rules in effect when arbitration begins, along with the procedures in this warranty section. The AAA Rules are available at www.adr.org/consumer.

You must send a copy of your written demand for arbitration, and a copy of this provision, to the AAA in the manner required by the AAA Rules. You must also send a copy to LG at the address above.

If there is a conflict between the AAA Rules and this warranty section, this warranty section controls. The Federal Arbitration Act governs this arbitration provision. The arbitrator’s award may be entered in any court with proper jurisdiction. The arbitrator decides all issues except the scope and enforceability of the arbitration provision and whether the dispute can be arbitrated; those issues are decided by a court.

Governing law The law of the state where you live governs this Limited Warranty and any disputes, except where federal law controls or conflicts.

Fees and costs in arbitration You do not have to pay a fee to begin arbitration. When LG receives your written demand, LG will promptly pay all arbitration filing fees to the AAA unless you are seeking more than $25,000 in damages. If so, fee payment is handled under the AAA Rules.

Except where otherwise stated, LG will pay AAA filing, administration, and arbitrator fees for arbitrations started according to the AAA Rules and this provision.

If you win arbitration, LG will pay your reasonable attorneys’ fees and expenses, considering factors such as the purchase amount and claim amount. If the law allows reasonable attorneys’ fees and expenses, the arbitrator may award them to the same extent a court could.

If the arbitrator decides your claim or the relief you requested is frivolous or brought for an improper purpose, fee payment follows the AAA Rules, and you agree to reimburse LG for amounts LG already paid that would otherwise be your responsibility. If LG wins, LG generally waives any right to seek attorneys’ fees and expenses from you.

Hearings and location If your claim is for $25,000 or less, you may choose arbitration based only on documents, by telephone, or by an in-person hearing, as allowed by the AAA Rules. If your claim exceeds $25,000, the AAA Rules decide whether there will be a hearing.

Any in-person hearing will be held in the federal judicial district where you live, unless both sides agree to another location or to a telephonic arbitration.

Opting out of arbitration You may opt out of this dispute resolution procedure. If you do, neither side can require the other to use arbitration.

To opt out, you must notify LG within 30 calendar days from the date of the first consumer purchaser’s purchase of the product. You may opt out only by: - emailing optout@lge.com with the subject line: “Arbitration Opt Out”, or - calling 1-800-980-2973

Your opt-out notice must include: - your name and address - the purchase date - the product model name or model number - the serial number

The serial number can be found on the product or online at https://www.lg.com/us/support by clicking “How do I find my model number?”

No other form of notice works to opt out. Opting out does not change your Limited Warranty coverage. If you keep the product and do not opt out, you accept the arbitration terms.

Canada: arbitration notice For Canada, the warranty says it contains an arbitration provision that requires disputes to be resolved by binding arbitration instead of court, unless provincial or territorial law does not allow it, or unless you opt out in jurisdictions where that option applies. It also says this arbitration provision does not apply to consumers in Ontario, British Columbia, or Québec. Class actions and jury trials are not allowed in arbitration.

Canada: warranty coverage If the washer fails because of a defect in materials or workmanship during normal and proper use, LG Electronics Canada, Inc. (LGECI) will, at its option, repair, replace, or provide a prorated remedy after receiving proof of the original retail purchase.

This warranty is only for the original retail purchaser and only for a product distributed, purchased from an authorized retailer, and used in Canada, as determined by LGECI.

Warranty periods in Canada If the original purchase date cannot be verified, the warranty starts 60 days from the date of manufacture.

  • Washer: 1 year from the original retail purchase date — parts and labor for internal/functional parts only
  • Stainless steel drum: 3 years from the original retail purchase date — parts only; consumer pays labor
  • Direct drive motor (stator or rotor): 10 years from the original retail purchase date — part only; consumer pays labor

Replacement products and parts are covered for the remaining original warranty period or 90 days, whichever is greater. Replacement products and parts may be new, reconditioned, refurbished, or factory remanufactured, at LGECI’s sole discretion.

You must provide proof of original retail purchase showing the model and purchase date to receive warranty service.

What the Canada warranty does not cover This Limited Warranty does not cover: - service trips to deliver, pick up, install, or teach product operation; correct wiring or plumbing; or correct unauthorized repairs or installations - damage or failure during power failures or interrupted/inadequate electrical service - damage or failure caused by leaky or broken water pipes, frozen pipes, restricted drain lines, or inadequate/interrupted water or air supply - damage or failure from corrosive atmospheres or from use contrary to the owner’s manual - damage or failure caused by accidents, pests, lightning, wind, fire, floods, acts of God, or other causes beyond LGECI’s or the manufacturer’s control - damage or failure caused by misuse, abuse, improper installation, repair, or maintenance; improper repair includes unauthorized parts, and improper installation or maintenance includes anything contrary to the owner’s manual - damage or failure from unauthorized modification, using the product for anything other than its intended household purpose, or water leakage due to improper installation - damage or failure from incorrect electrical current, voltage, or plumbing codes - damage or failure from use other than normal household use, including commercial or industrial use, unless otherwise stated in the owner’s manual - damage or failure caused by accessories, components, or cleaning products that are not approved/authorized by LGECI - transportation and handling damage, including scratches, dents, chips, or finish damage, unless it results from defects in materials or workmanship and is reported within 1 week of delivery - damage or missing items to display, open-box, refurbished, or discounted products - refurbished products or products sold “As Is”, “Where Is”, “With all Faults”, or similar - products with original serial numbers removed, altered, or not readily determinable - higher utility costs or added utility expenses related to the product - replacement of light bulbs, filters, fuses, or other consumable parts - costs to remove and/or reinstall the product for repairs - noises that are normal for operation, or failures caused by not following the use and care or installation guides, or by using the unit in an unsuitable environment

Other Canada warranty notes LGECI says this limited warranty is the only liability it accepts, unless provincial law prevents that limitation. Other warranties or conditions, including implied warranties of merchantability or fitness for a particular purpose, are disclaimed except where prohibited by provincial law. If law implies a warranty or condition, it is limited to the warranty period above.

LGECI is not responsible for incidental, consequential, special, direct, indirect, punitive, or exemplary damages, including loss of goodwill, lost profits, lost revenue, loss of use, or similar damages. LGECI’s total liability, if any, does not exceed the purchase price you paid for the product.

This warranty gives you specific legal rights, and you may have other rights that vary by province. If any term conflicts with provincial law, that term is severable and the rest of the warranty remains in effect.

Limited Warranty: what happens if there is a dispute

This section explains how warranty disputes are handled for LG Canada.

In-home repairs and service area - For products that are still in warranty, in-home repairs are provided only if the product is within a 150 km radius of the nearest authorized service center, as determined by LG Canada. - If the product is outside that 150 km radius, you are responsible for bringing the product to the authorized service center at your own expense for in-warranty repair. - Any costs tied to excluded circumstances listed in the warranty’s “This Limited Warranty Does Not Cover” section must be paid by the consumer.

How to get warranty service or more information - Call 1-888-542-2623. - Hours: 8 am to 9 pm EST, 365 days. - You can also visit http://www.lg.com.

Dispute resolution: arbitration instead of court

Except where the law prohibits it, all disputes between you and LG that arise from or relate to the limited warranty or the product are to be resolved through binding arbitration, not in a court of general jurisdiction.

The warranty says that, except where prohibited by law, you and LG: - waive the right to a jury trial; and - waive the right to bring or join a class action.

What counts as a dispute For this section, a dispute or claim includes any disagreement of any kind related to: - the sale of the product, - the condition of the product, - the performance of the product, or - the limited warranty itself.

Notice of dispute If you want to start arbitration, you must first give LG written notice at least 30 days before starting arbitration.

Send the notice to: - LGECI Legal Team - 20 Norelco Drive, North York, Ontario, Canada M9L 2X6

Your notice must include: - your name, - your address, - your telephone number, - the product involved, - the nature of the claim, and - the relief you want.

After LG receives the notice, you and LG are expected to try to resolve the claim in good faith. If the dispute is not resolved within 30 days after LG receives the notice, it goes to binding arbitration.

How arbitration works - Arbitration is private and confidential. - It is conducted on a simplified and expedited basis. - A single arbitrator is chosen by the parties under the commercial arbitration law and rules of your province or territory. - You must also send a copy of the written arbitration demand to LG Electronics Canada, Inc., Attn: Legal Department – Arbitration, 20 Norelco Drive, North York, Ontario M9L 2X6. - Judgment on the arbitrator’s award may be entered in any court that has jurisdiction. - The arbitrator decides all issues except questions about whether the arbitration clause applies and whether the dispute can be arbitrated; those questions are for the court.

Governing law and court jurisdiction - The law of the province or territory where you purchased the product governs the limited warranty and any disputes with LG, except where that law conflicts with applicable federal or provincial/territorial law. - If arbitration is not permitted for a claim, dispute, or controversy, you and LG agree to the exclusive jurisdiction of the courts of the province or territory where the product was purchased.

Fees and costs in arbitration - You do not need to pay any fee to begin arbitration. - LG will promptly pay all arbitration filing fees after receiving your written demand, unless you are seeking more than $25,000 in damages; in that case, the applicable arbitration rules control fee payment. - In general, LG pays the filing, administration, and arbitrator fees for arbitration started under the arbitration provision and applicable rules. - If you win, LG will pay your reasonable attorneys’ fees and expenses, considering factors such as the purchase amount and claim amount. - If the arbitrator decides your claim or requested relief is frivolous or brought for an improper purpose, fee payment follows the applicable arbitration rules, and you agree to reimburse LG for amounts LG paid that are otherwise your responsibility. - If LG wins, LG waives any right it may have to seek attorneys’ fees and expenses from you, except as otherwise provided.

Hearings and location - If your claim is $25,000 or less, you may choose one of these options: - document-only arbitration, - a telephone hearing, or - an in-person hearing, as allowed by the arbitration rules. - If your claim is over $25,000, the right to a hearing is determined by the arbitration rules. - In-person hearings are held at the nearest mutually convenient arbitration location in your province or territory, unless you and LG agree to another location or to a telephone arbitration.

Severability and waiver - If part of this limited warranty, including the arbitration procedures, is unenforceable, the rest remains in effect to the fullest extent allowed by law. - If LG does not strictly enforce a provision, that does not mean LG waives that provision.

Opting out of arbitration If you are covered by the binding arbitration provision, you may opt out.

How to opt out You must notify LG no later than 30 calendar days from the date of the first consumer purchaser’s purchase of the product.

You can opt out only by: - emailing optout@lge.com with the subject line “Arbitration Opt Out;” or - calling 1-800-980-2973.

Your opt-out notice must include: - your name and address, - the date the product was purchased, - the product model name or model number, and - the serial number.

The serial number can be found: - on the product, or - online at https://www.lg.com/ca_en/findmodel_serial/.

What happens if you opt out - If you opt out, neither you nor LG can require the other to participate in arbitration. - The law of the province or territory where you live governs the limited warranty and disputes, except where preempted by or inconsistent with applicable law. - If arbitration is not permitted for a claim or dispute, you and LG agree to the exclusive jurisdiction of the courts of your province or territory of residence. - Opting out does not affect your limited warranty coverage. - If you keep the product and do not opt out, you accept the arbitration terms.

Conflict with the EULA If there is a conflict between this limited warranty and the End User License Agreement (EULA) about dispute resolution, the limited warranty controls and takes priority.
