Online Manual Notice and What These Pages Tell You
These first pages of the owner’s manual mainly serve as the starting point for the full manual.
What the manual says - This is the OWNER'S MANUAL for an LG dryer. - The manual applies to models DL*X400 and DL*X408. - The document advises you to read the owner’s manual thoroughly before operating the appliance and to keep it handy for reference at all times. - The pages shown here are labeled as the beginning of the manual and include the table of contents for the full guide.
What is covered in the full manual The table of contents shows the major sections that follow these pages: - Important Safety Instructions - Warning Statements - Product Overview and Product Features - Installation - Before Installing - Choosing the Proper Location - Leveling the Appliance - Reversing the Door - Installing the Vent Kit - Stacking the Appliance - Venting the Dryer - Connecting Gas Dryers - Connecting Electric Dryers - Connecting the Water Inlet Hose - Final Installation Check - Operation - Before Use - Loading the Dryer - Control Panel - Dry Cycles - Cycle Modifiers - Options and Extra Functions - Smart Functions - LG ThinQ Application - Smart Diagnosis™ Function - Maintenance - Regular Cleaning - Troubleshooting - FAQs - Before Calling for Service - Limited Warranty for the USA
Practical takeaway If you are looking at only these pages, the main useful instruction is simple: do not start using the dryer until you have read the full owner’s manual, especially the safety and installation sections listed in the contents. These pages do not provide operating steps, settings, or maintenance instructions yet—they only tell you where to find them in the full manual.
Warranty section note The table of contents shows that a Limited Warranty section is included for the USA, but these pages do not show the warranty terms themselves. To understand coverage, exclusions, or how to make a claim, you would need the pages in that section.
Keep in mind Because these pages are only the opening pages and contents list, they do not include: - specific safety warnings - installation measurements or procedures - cycle names or control settings - cleaning instructions - troubleshooting steps - warranty details
For those details, you would need the later pages named in the contents.

- Use an individual, grounded electrical outlet located within 2 ft. (61 cm) of either side of the appliance.
- Do not install or store the appliance where it will be exposed to water and/or weather.
- Check local code requirements. Some areas limit or do not permit dryer installation in garages, mobile homes, or sleeping quarters. If you have questions, contact your local building inspector.
Garage installation
If you install the dryer in a garage, place the appliance at least 18 inches (45.7 cm) above the floor.
- The manual says the standard pedestal height is 15 inches (38 cm).
- You need 18 inches (45.7 cm) from the garage floor to the bottom of the appliance.
Ambient temperature
Install the appliance where the temperature is over 45 °F (7 °C).
If the temperature around the appliance is too low, the appliance might not shut off at the end of an automatic cycle. This can cause longer drying times.
Flooring and leveling
The dryer should be installed and leveled on a solidly constructed floor with a maximum slope of 1 inch (2.5 cm).
- If needed, adjust the leveling legs to compensate for an uneven floor.
- A sturdy floor is necessary to support the total appliance weight when loaded.
- If other appliances will be nearby, their weight should also be considered.
- If the dryer is not level, clothes may not tumble properly and automatic sensor cycles may not work correctly.
Recessed area or closet installation
The manual provides recommended clearances for recessed areas and closets.
Recommended installation spacing includes:
- Upper ventilation opening: 2 openings totaling 48 sq. in. (310 cm²)
- Lower ventilation opening: 2 openings totaling 24 sq. in. (155 cm²)

Leveling and door reversal
Leveling the Dryer
Proper leveling is important for performance. The dryer must be level to help provide optimal drying performance. A perfectly level, solid floor helps minimize vibration, noise, and unwanted movement.
Before you begin - Wear long-sleeved gloves and safety glasses. - The appliance is heavy. Two or more people are required for installation. - If the dryer is being installed on the optional pedestal, use the leveling feet on the pedestal to level the appliance. The dryer’s own leveling feet should be fully retracted.
Check the level 1. Move the appliance into its final location. 2. Place a level across the top of the appliance. 3. Check that all four leveling feet rest solidly on the floor. 4. Gently push on the top corners of the appliance to make sure it does not rock from corner to corner.
Adjust the leveling feet - Use an adjustable wrench to turn the leveling feet. - Unscrew the legs to raise the appliance. - Screw in the legs to lower the appliance. - Adjust only as much as needed to make the dryer level from side to side and front to back. - Make sure all four leveling feet remain in firm contact with the floor.
Important leveling note Do not extend the leveling feet more than necessary. Extending them too far may cause the appliance to vibrate.
Reversing the Door
These instructions change the door swing from a right-side hinge to a left-side hinge. If the door has already been reversed and you need to change it back, follow the steps carefully because the left/right references will be reversed.
Before you begin - Support the door with a stool or box that fits under the door, or have another person support the door’s weight. - Avoid dropping the door. - Unplug the appliance or turn off power at the main circuit breaker before starting. - Always reverse the door before stacking the appliance on top of the washer.
Tools required - Phillips screwdriver - Large flat blade screwdriver, recommended if hinge screws are tight or the Phillips screwdriver is worn - Small flat blade screwdriver, for lifting out parts
Door reversal step shown on this page 1. Open the door. 2. Remove the 2 decorative screws, 2 latch screws, and the latch from the catch side with a screwdriver. 3. Save these parts for step 4. 4. Be sure to keep supporting the weight of the door before removing the hinge screws.
Only this first door-reversal step is shown on this page. Continue with the remaining instructions from the manual if you are completing the full door reversal.

Vent kit installation and vent routing
Vent kit installation and vent routing
This dryer is configured to vent to the rear, but it can also vent to the bottom or side.
Before you begin - Wear long-sleeved gloves and safety glasses. - Use a heavy metal vent. - Do not use plastic or thin foil ducts. - Clean old ducts before installing the appliance. - Ductwork and fittings are not included and must be purchased separately. - If you want to change the vent location, an adapter kit, part number 383EEL9001B, may be purchased from your LG retailer. - Right-side venting is not available on gas models.
Important venting rules - Gas dryers must exhaust to the outdoors. - Do not vent into an enclosed or unventilated area, such as an attic, wall, ceiling, crawl space, chimney, gas vent, or concealed space of a building. - Do not exceed the recommended duct length limits. - Do not crush or collapse ductwork. - Do not let ductwork rest on or contact sharp objects. - If you connect to existing ductwork, make sure it is suitable and clean before installing the dryer. - Venting must conform to local building codes. - Use only 4-inch (10.2 cm) rigid, semi-rigid, or flexible metal ductwork inside the dryer cabinet and for venting outside. - The exhaust duct must be 4 inches (10.2 cm) in diameter and have no obstructions. - Keep the exhaust duct as short as possible. - Use rigid, semi-rigid, or flexible metal ducting between the dryer and the wall. All non-rigid metal transition duct must be UL-listed. - Do not use sheet metal screws or other fasteners that extend into the duct and could catch lint. Secure all joints with duct tape. - The vent hood should have hinged dampers to prevent backdraft when the dryer is not in use. - When pushing the dryer into place, do not crush or collapse the ductwork.
Flexible duct limit - The total length of flexible metal duct must not exceed 8 ft. (2.4 m).
Maximum rigid duct length The maximum length of 4-inch diameter rigid metal duct depends on the wall cap and the number of 90° elbows.
For the recommended 4-inch wall cap: - 0 elbows: 65 ft. (19.8 m) - 1 elbow: 55 ft. (16.8 m) - 2 elbows: 47 ft. (14.3 m) - 3 elbows: 36 ft. (11.0 m) - 4 elbows: 28 ft. (8.5 m)
For the 2.5-inch wall cap, use only for short run installations: - 0 elbows: 55 ft. (16.8 m) - 1 elbow: 47 ft. (14.3 m) - 2 elbows: 41 ft. (12.5 m) - 3 elbows: 30 ft. (9.1 m) - 4 elbows: 22 ft. (6.7 m)
Notes: - Deduct 6 ft. (1.8 m) for each additional elbow. - Do not use more than four 90° elbows.
Side venting 1. Remove the rear exhaust duct retaining screw and pull out the exhaust duct. 2. Press the tabs on the knockout and carefully remove the knockout for the desired vent opening. Right-side venting is not available on gas models. 3. Press the adapter duct onto the blower housing and secure it to the base of the dryer as shown. 4. Preassemble a 4" (10.2 cm) elbow to the next 4" (10.2 cm) duct section, and secure all joints with duct tape. 5. Make sure the male end of the elbow faces away from the dryer. 6. Insert the elbow/duct assembly through the side opening and press it onto the adapter duct. 7. Secure it in place with duct tape. 8. Make sure the male end of the duct protrudes 1.5" (3.8 cm) so it can connect to the remaining ductwork. 9. Attach the cover plate to the back of the dryer with the included screw.
Bottom venting 1. Remove the rear exhaust duct retaining screw. 2. Pull out the exhaust duct. 3. Press the adapter duct onto the blower housing and secure it to the base of the dryer as shown. 4.

Steam water inlet connection
Connecting the Steam Water Inlet Hose
To use steam, the dryer must be connected to the cold water tap with a new water supply hose. Do not use old hoses.
Before you begin: - Make sure you have a suitable cold water faucet. - Use only new hoses for installation. - If your water supply has a lot of debris, a whole home water filter may help keep debris from reaching the dryer inlet. - Do not install or store the appliance where it may be exposed to freezing temperatures.
Important hose and water-supply limits - Check hoses regularly for cracks, leaks, and wear. - Replace hoses every five years. - Do not stretch the hoses on purpose. - Do not let hoses become pinched, crushed, or kinked. - Water supply pressure must be between 20 psi and 120 psi (138 - 827 kPa). - If water pressure is above 120 psi, a pressure reducing valve must be installed. - Do not use flood-preventing hoses with auto shut off devices. These can be tripped during filling and prevent proper filling. - If the appliance was exposed to freezing temperatures before installation, allow it to stand at room temperature for several hours before use and check for leaks before operating.
Step 1: Inspect the hoses and seals Check the threaded fitting on each hose. - Make sure a rubber seal is in place at both ends of each hose. - This helps prevent leaking.
Step 2: Connect the hoses to the faucet Connect all water supply hoses tightly by hand, then tighten another 2/3 turn with pliers.
Do not overtighten or cross-thread the fittings. Overtightening or cross-threading can damage the valves or couplings and cause leaking and property damage.
Step 3: Choose the correct installation type
Type 1: Without washer sharing the faucet Use this setup when the dryer does not share the faucet with a washing machine. 1. Connect the straight end of the long hose to the cold water faucet. 2. Connect the long dryer hose to the dryer inlet valve. Tighten it by hand, then tighten another 2/3 turn with pliers. 3. Turn on the cold water faucet.
Type 2: With washer sharing the faucet Use this setup when the dryer shares the faucet with a washing machine. 1. Shut off the cold water tap and remove the washer inlet hose. 2. Connect the short hose to the Y-connector using one of the rubber seals. 3. Connect the other end of the short hose to the cold water faucet. 4. Connect the long dryer hose to one side of the Y-connector. Connect the washer hose to the washer and the other side of the Y-connector. 5. Connect the long dryer hose to the dryer inlet valve tightly by hand, then tighten another 2/3 turn with pliers. 6. Turn on the cold water faucet.
Step 4: Flush the water line Before connecting the water line to the dryer, flush several gallons of water into a drain or bucket. This helps remove foreign particles such as sand and scale so they do not clog the dryer inlet valve.
Step 5: Check for leaks Check all hoses and Y-connectors, if used, for leaks.
If you find a leak: - Shut off the water faucet. - Remove the hose. - Check the condition of the rubber seal.
Hard water note In areas with hard water, mineral scale can build up on internal components. Using a water softener is recommended. Excessive scale buildup may eventually require part replacement or repair.
Quick checklist - New hose only, no old hoses - Rubber seals installed at both ends - Tighten by hand, then 2/3 turn with pliers - No leaks at hoses or Y-connector - Cold water faucet turned on - Hose is not pinched, crushed, or kinked - Water pressure is within the stated range
When to stop and correct the installation Stop and recheck the connection if: - The hose leaks - The fittings were overtightened or cross-threaded - The hose has no rubber seal - The water line was not flushed before connection - The hose uses an auto shut off flood-preventing device
FAQ
Q: Can I use my old water hose? A: No. The manual says to use a new water supply hose and not to reuse old hoses.
Q: How tight should the hose connections be? A: Tighten the hoses by hand, then use pliers for another 2/3 turn. Do not overtighten.
Q: What should I do if I find a leak? A: Shut off the faucet, remove the hose, and check the rubber seal.
Q: Can I use a hose with an auto shut off device? A: No. The manual says not to use flood-preventing hoses with auto shut off devices.
Q: What water pressure is allowed? A: The water supply pressure must be between 20 psi and 120 psi (138 - 827 kPa).
Q: Do I need to flush the water line first? A: Yes. The manual says to flush several gallons of water into a drain or bucket before connecting the line to the dryer.
Q: What if my home has hard water? A: The manual recommends using a water softener in areas with hard water.

Final installation checks and test run
Final installation checks and test run
Before using the dryer normally, make three final checks: levelness, airflow, and the installation test.
1) Check that the dryer is level Once the dryer is in its final location, recheck it to make sure it is level: - front to back - side to side - all four leveling feet should be in firm contact with the floor
2) Check airflow Good dryer performance depends on proper airflow. The manual says airflow can be checked by measuring static pressure in the exhaust duct with a manometer.
- Place the manometer on the exhaust duct about 2 ft. (60.9 cm) from the dryer
- Check the dryer while it is running with no load
- Static pressure in the exhaust duct should not exceed 0.6 inch (1.5 cm)
If the ductwork is crushed or restricted, or if there are blockages or lint buildup, airflow can be poor. The manual also notes that long exhaust runs, multiple elbows, bends, excess transition duct, or crushed transition duct can restrict airflow.
3) Run the installation test This test is meant to confirm that the exhaust system is adequate for proper operation. The appliance should be cool before you start. If it was warmed up during installation, run the Air Dry cycle for a few minutes first to lower the interior temperature.
Flow SenseTM is a sensing system that detects blockages and restrictions in the dryer ductwork. Keeping the ductwork clean and free of restrictions helps clothes dry faster and reduces energy use.
Before you start - Remove the drying rack and literature - Close the door - Do not load anything in the drum for this test, because that can affect the accuracy of the results
How to activate the installation test 1. Press and hold the Signal and Temp. buttons, then press the Power button. - On models with a glass touch control panel, press Power first, then immediately press and hold Signal and Temp. - If the activation is successful, code 1Ns will display. 2. Press Start/Pause. - The test lasts a few minutes. - Heat will turn on and the temperatures in the drum will be measured. 3. Check the display and Flow SenseTM LED when the test ends.
How to read the result - If the Flow SenseTM LED does not turn on when the cycle ends, the exhaust system is adequate. - If the Flow SenseTM LED turns on, the exhaust system is severely restricted and should be checked immediately, because performance will be poor. - Other problems may also appear as error codes. - At the end of the test cycle, ENd will display and the appliance will shut off automatically after a short delay.
If the test shows a problem If the Flow SenseTM LED turns on, check the exhaust system for restrictions and damage, then repair or replace it as needed.
The manual also says: - Do not interrupt the test cycle, or the results may be inaccurate - Even if the LED does not light during the test, some restrictions may still be present - Refer to the Venting the Dryer section for complete exhaust system and venting requirements
Error codes mentioned in this section - Ps, PF, or NP: electric dryer power cord is not connected correctly, or house power supply is incorrect. Reset the circuit breaker or replace the fuse. Do not increase the fuse capacity. If the problem is a circuit overload, have it corrected by a qualified electrician. - GAs: gas supply or service is turned off, gas model only. Confirm that the house gas shutoff and the dryer gas shutoff are both fully open. - tE1 or tEz: temperature sensor failure. Turn off the appliance and call for service. - Hs: humidity sensor failure. Turn off the appliance and call for service.
Important reminders - Make sure the ductwork is not crushed or restricted. - The installation test is for alerting you to serious problems in the home exhaust system. - The normal operating test may give more accurate information than the installation test, so the results of the two tests may not match exactly.

1) Clean the lint filter before every load - Always make sure the lint filter is clean before starting a new load. - A clogged lint filter will increase drying time. - If the lint filter has not already been cleaned, lift it out and remove the lint from the last load. - Reinstall the filter by pressing it down firmly until it clicks into place. - Make sure the lint filter is properly installed before running the dryer. - Running the dryer with a loose or missing lint filter will damage the dryer and articles in the dryer.
2) Load the dryer correctly - Push clothing entirely into the drum and keep it away from the door seal area. - Clothing caught between the door and seal may be damaged or may damage the seal. - If a load is extra large, divide it into smaller loads for proper performance and fabric care. - Tie and secure all strings and attached belts before placing clothes in the drum. - Do not overload the dryer. - For the best drying performance and the most efficient energy use, avoid overloading. - Damp clothes expand as they dry, so leave enough room for items to tumble freely. - Combine large and small items in the same load when appropriate.
3) Sort laundry by fabric and care needs - Sort and dry laundry according to care labels, size, and fabric type. - Group similar items into loads that can be dried with the same cycle. - Different fabrics have different care requirements, and some dry more quickly than others. - Use mesh laundry bags for clothes with zippers, hooks, straps, and drawstrings to help prevent catching, tangling, or damage to the lint filter.
Fabric-care guidance - Some woven and loopknit materials may shrink, depending on quality. - For permanent press and synthetics, do not overload the dryer. Remove permanent press items as soon as the dryer stops to reduce wrinkles. - For baby clothes and nightgowns, always check the manufacturer’s instructions. - Do not dry items made from or containing rubber or plastics, such as aprons, bibs, chair covers, curtains, tablecloths, and bath mats. - Do not dry fiberglass articles. Glass particles left in the dryer could be picked up by other clothes later and irritate your skin. - For woolen items, always follow the fabric care labels before drying. After the cycle, wool items may still be damp. Do not repeat the cycle. Pull items back to their original shape if needed and lay them flat to finish drying.
4) Choose a cycle - Turn the cycle selector knob in either direction until the LED for the desired cycle is on. - The preset temperature, dry level, and option settings for that cycle will be shown. - If you press Start/Pause without selecting a cycle, the dryer immediately starts the Normal cycle with the default settings. - Select the Normal cycle if you want to change the default settings.
5) Adjust settings - You may change the default settings for the selected cycle using the cycle modifier and option buttons. - Not all modifiers and options are available on all cycles. - If a selection is not allowed, a different chime will sound and the LED will not come on.
6) Start the cycle - Press Start/Pause to begin. - You can pause the cycle at any time by opening the door or pressing Start/Pause. - If Start/Pause is not pressed within a certain time, the dryer shuts off and all settings are lost.
7) When the cycle ends - When the cycle is finished, a chime will sound. - Remove clothing from the dryer immediately to reduce wrinkling. - If Wrinkle Care is selected, the dryer will tumble briefly every few minutes to help prevent wrinkles from setting in.
Fabric care label reminders - Tumble dry labels may indicate Dry, Normal, Permanent Press/Wrinkle Resistant, or Gentle/Delicate. - Some labels indicate Do not tumble dry or Do not dry. - Heat-setting labels may indicate High, Medium, Low, or No Heat/Air. - Use the care label and the manufacturer’s recommendations to help choose the correct cycle and options.

Routine maintenance and lint filter care
Routine maintenance and lint filter care
Keeping the lint filter and exterior clean helps the dryer run safely and efficiently. Follow these care steps regularly.
Before you clean - Unplug the appliance before cleaning. - Do not use harsh chemicals, abrasive cleaners, solvents, methylated spirits, or similar products on the appliance. These can damage the finish. - Never use steel wool or abrasive cleansers on any part of the dryer.
Clean the lint filter after every cycle Always remove lint from the filter after every drying cycle.
How to clean the lint filter 1. Open the dryer door. 2. Pull the lint filter straight up. 3. Remove lint from the filter: - For everyday cleaning, roll the lint off with your fingers, or - Vacuum the lint filter.
If the filter is heavily soiled If the lint filter becomes very dirty or clogged with fabric softener, wash it in warm, soapy water. - Let it dry thoroughly before putting it back in the dryer. - Never operate the appliance without the lint filter in place.
Clean the exterior Proper care can help extend the life of the appliance. - Clean the outside with warm water and a mild, nonabrasive household detergent. - Immediately wipe off any spills with a soft, damp cloth.
Clean the interior surfaces - Wipe around the door opening and seal with a soft, damp cloth to help prevent lint and dust buildup that could damage the door seal. - Clean the window with a soft cloth dampened with warm water and a mild, nonabrasive household detergent, then wipe it dry. - The stainless steel drum can be cleaned with a conventional stainless steel cleaner, used according to the manufacturer’s instructions.
Clean around and under the appliance Vacuum lint and dust from around the dryer and underneath it regularly.
Check ductwork regularly Vent ductwork should be checked for lint buildup once per month and cleaned at least once per year. - If you notice reduced airflow or drying performance, check the ductwork right away for obstructions and blockages. - Contact a qualified technician or service provider if needed.
Quick reminders - Clean the lint filter after every cycle. - Do not run the dryer without the lint filter installed. - Use only mild, nonabrasive cleaners and soft cloths for cleaning.

Frequently asked questions
Frequently Asked Questions
Why does my dryer beep when I press a button and then nothing happens? If the dryer beeps but does not start, the Control Lock feature is turned on. To turn Control Lock off, turn the dryer on and then press and hold the button that has Control Lock on or under it for 3 seconds.
Why does my dryer take so long to dry clothes? Drying time depends on airflow. Proper airflow is critical for efficient dryer operation. If the lint filter is full of lint or clogged with fabric softener sheet residue, airflow can be reduced and the time needed to dry clothes can increase a lot. The manual also says to see the troubleshooting charts for more tips.
Why does my dryer start by itself every few minutes? This is normal behavior when Wrinkle Care is on. After the cycle ends, the dryer runs briefly every few minutes for up to 3 hours. The feature is meant to help prevent wrinkles from setting in if you do not unload the dryer right away.
Why does my dryer show 3 minutes when I select the Steam FreshTM cycle? When Steam FreshTM is selected, the display shows the recommended number of garments for the cycle, not the estimated cycle time, until you start the cycle. Use the More Time or Less Time buttons to change the load size setting to the number of garments you want. For a large load or a single bulky item, use the 6IQ (big) setting.
Need more help? LG says additional help is available through support videos and tutorials on the LG website. The manual directs you to the LG support site, then to Video Tutorials, and suggests searching for Dryer on that page.

Troubleshooting by symptom: power and heating
Troubleshooting by symptom: power and heating
Use these checks when the dryer will not start, will not heat, or is drying much more slowly than expected. Only the causes and fixes listed here are supported by the manual.
The appliance will not turn on
Possible cause: - House fuse is blown, circuit breaker has tripped, or a power outage has occurred.
What to do: - Reset the circuit breaker or replace the fuse. - Do not increase fuse capacity. - If the problem is a circuit overload, have it corrected by a qualified electrician.
The appliance does not heat
Possible causes: - House fuse is blown, circuit breaker has tripped, or a power outage has occurred. - Gas supply or service is turned off. - Energy Saver option is selected.
What to do: - Reset the circuit breaker or replace the fuse. Do not increase fuse capacity. - If the problem is a circuit overload, have it corrected by a qualified electrician. - Confirm that the hose gas shutoff and the shutoff valves of the dryer are both fully open. - Even if gas is not supplied to the appliance, it will run and no error codes will display. Verify that other gas appliances in the home are working normally. - If using the Normal cycle, deselect the Energy Saver option that is selected by default. - This option reduces energy use by adding an air dry section to the beginning of the cycle. - It is normal to feel no heat at the beginning of the cycle while in Energy Saver mode.
Clothes take too long to dry
Possible causes and actions:
Exhaust ducts are blocked, dirty, or the duct run is too long - Confirm that the exhaust duct is properly configured and free of debris, lint, and obstructions. - Make sure that the outside wall damper can open properly and is not blocked, jammed, or damaged.
Load is not properly sorted - Separate heavy items from lightweight items. - Larger and heavier items take longer to dry. - Light items in a load with heavy items can fool the sensor because the light items dry faster.
Large and heavy fabrics are loaded - Heavy fabrics take longer to dry because they tend to retain more moisture. - To help reduce and maintain more consistent drying times for large and heavy fabrics, separate these items into smaller loads of a consistent size.
Dryer controls are not set properly - Use the appropriate control settings for the type of load you are drying. - Some loads may require an adjustment of the dry level setting for proper drying.
Lint filter needs to be cleaned - Remove the lint from the filter before every load. - With the lint removed, hold the filter up to a light to see if it is dirty or clogged. - With some loads that produce high amounts of lint, such as new bath towels, it may be necessary to pause the cycle and clean the filter during the cycle.
House fuse is blown, circuit breaker has tripped, or power outage has occurred - Reset the circuit breaker or replace the fuse. - Do not increase fuse capacity. - If the problem is a circuit overload, have it corrected by a qualified electrician.
The appliance is overloaded - Divide extra large loads into smaller loads for better drying performance and efficiency.
The appliance is underloaded - If you are drying a very small load, add a few extra items to ensure proper tumble action. - If the load is small and you are using SENSOR DRY cycles, the electronic control cannot properly sense the dryness of the load and may shut off too soon. - Use MANUAL DRY cycles or add some extra wet clothes to the load.
Energy Saver option is selected - If using Normal cycle, deselect the Energy Saver option that is selected by default. - This option reduces energy use by adding an air dry section to the beginning of the cycle. - It is normal to feel no heat at the beginning of the cycle while in Energy Saver mode.

Troubleshooting by symptom: drying results and wrinkles
Troubleshooting by symptom: drying results and wrinkles
Use the guidance below when clothes are drying unevenly, coming out wrinkled, feeling staticky, or still have damp spots after a cycle. These tips focus on load size, fabric type, dryness settings, and how long items stay in the dryer.
Drying time is not consistent Drying time can vary from load to load. This is normal when any of the following changes: - load size - fabric type - how wet the clothes are - the condition of the lint filter
An unbalanced load in the washer can also cause poor spinning. If clothes come into the dryer wetter than usual, they may take longer to dry.
Clothes are wrinkled Wrinkling can happen when a load is overdried. - Try a shorter drying time. - Or use a lower dry level setting. - Remove items while they still retain a slight amount of moisture.
Wrinkles can also form if clothes stay in the dryer after the cycle ends. - Use the Wrinkle Care option. It tumbles clothes briefly every few minutes for up to 3 hours to help prevent wrinkling.
Greasy or dirty spots on clothes If clothes have greasy or dirty spots after drying: - Check that fabric softener is being used correctly, and follow the instructions that come with it. - Dry only clean items. Soil from dirty clothes can transfer to clean clothes in the same load or later loads. - Make sure clothes were properly cleaned or rinsed before drying. - Some difficult soils may need pre-treatment before washing.
Clothes are shrinking To avoid shrinking: - Follow the garment care instructions. - Use a low heat or no heat setting when appropriate.
Some fabrics naturally shrink when washed. Others may wash okay but shrink in the dryer.
Lint on clothes If lint is left on clothes, the lint filter may not be cleaned properly. - Remove lint from the filter before every load. - After removing the lint, hold the filter up to a light to see whether it is dirty or clogged. - If it looks dirty, follow the cleaning instructions in the maintenance section. - For loads that produce a lot of lint, it may be necessary to clean the filter during the cycle.
Sorting also matters: - Some fabrics produce lint, such as a fuzzy white cotton towel. - Other fabrics trap lint, such as black linen pants. - Dry lint producers separately from lint trappers.
Excess static in clothes Static can increase when clothes are overdried. - Use a fabric softener to reduce static electricity, and follow the manufacturer’s instructions. - Adjust settings and use a shorter drying time, or use Sensor Dry cycles. - Divide extra large loads into smaller loads. - Check pockets before washing and drying to remove tissue, paper, and similar items.
If static is still a problem, the manual also notes these points: - Use a fabric softener or the Reduce Static option, if available. - Synthetic fabrics, permanent press, and synthetic blends are naturally more prone to static buildup. - For Manual Dry cycles, try a lower dry level setting and/or shorter time settings.
Clothes have damp spots after a Sensor Dry cycle If some items are still damp after Sensor Dry: - The load may be too large or too small for the sensor to read dryness correctly. - If the load is very small, use a Time Dry cycle. - Large items like blankets or comforters can wrap into a tight ball. The outside may dry while the inside stays damp. - When drying a single bulky item, pause the cycle once or twice and rearrange the item to unwrap it and expose damp areas. - To finish a few damp items from a very large load, or to dry damp spots on a large item after a sensor cycle, empty the lint trap and use a Time Dry cycle.
Steam cycle notes related to wrinkles and moisture For Steam functions, a few conditions are normal: - Water dripping from the nozzle when a Steam Cycle starts is normal steam condensation and should stop after a short time. - Water dripping from the door during a Steam Cycle is normal. - Steam vapor may be difficult to see during operation.
For Steam Fresh: - Small loads of 1 to 5 items work best. - Load fewer garments and load similar types of garments. - The cycle is meant to remove wrinkles; use an iron to restore creases and pleats.
For Reduce Static: - Select the load weight manually before starting the cycle. - If steam does not generate and no error code is shown, the manual says there is a water level error. Unplug the dryer and call for service.
Quick reminders - Clean the lint filter before every load. - Use Sensor Dry, Time Dry, or Manual Dry settings as needed for the load. - Keep load size and fabric types in mind when choosing a cycle. - When in doubt, stop overdrying; slightly damp clothes are less likely to wrinkle or build static.

Troubleshooting by symptom: steam, odor, and Wi-Fi
Troubleshooting: Steam, Odor, and Wi‑Fi
Use this section when you notice steam behavior that seems unusual, odors in clothing or inside the appliance, or problems connecting to Wi‑Fi.
Steam cycle questions
Problem: Drum does not turn during Steam Cycle
This is normal. - The drum is turned off so the steam vapor stays in the drum. - The drum normally turns for about 2 seconds once a minute.
Problem: Cannot see steam vapor at the beginning of cycle
This is normal. - Steam is released at different stages of the cycle for each option.
Problem: Odors remain in clothing after Steam Fresh™
Steam Fresh™ may not remove strong odors completely. - Fabrics with strong odors should be washed in a normal cycle.
Odor concerns
Problem: The appliance has an unpleasant odor
If the appliance is new, the odor may be caused by the rubber material inside the appliance. - This odor is normal when the appliance is new. - It should disappear after you run several cycles.
If you smell an odor during use: - Do not exceed the detergent amount recommended by the manufacturer when washing clothes. Too much detergent can build up on clothing and cause odors. - Do not leave clothes in the washer or dryer after the cycle ends. Unload clothing promptly when the cycle ends. - Keep lint filters clean. Dirty or clogged lint filters can cause odors. - After cleaning the lint filter, let it dry completely before using it again.
Wi‑Fi connection problems
Problem: Trouble connecting the appliance and smartphone to the Wi‑Fi network
Check these possible causes and fixes: - The Wi‑Fi password may have been entered incorrectly. Delete your home Wi‑Fi network and start the connection process again. - Mobile data on your smartphone may be turned on. Turn off mobile data before connecting the appliance. - The wireless network name (SSID) may be set incorrectly. The SSID should use only English letters and numbers. Do not use special characters. - The router frequency may not be 2.4 GHz. Only a 2.4 GHz router frequency is supported. Set the router to 2.4 GHz and connect again. If needed, check the router frequency with your Internet service provider or the router manufacturer. - The appliance and router may be too far apart. A weak signal can prevent a correct connection. Move the router closer to the appliance or install a Wi‑Fi repeater.
If the app asks for a product password during Wi‑Fi setup
On some phones, the app may ask for a password to connect to the product. - Find the network name that starts with “LG” under Settings > Networks. - Note the last part of the network name.
Use the correct password format based on the network name: - If the network name looks like LGE_Appliance_XX-XX-XX, enter lge12345. - If the network name looks like LGE_Appliance_XXXX, enter the last 4 characters twice as the password. - Example: if the network name is LGE_Appliance_8b92, enter 8b928b92. - This password is case sensitive. - The last 4 characters are unique to your appliance.

Dispute resolution and arbitration This warranty includes an arbitration provision.
Main points - Most disputes between you and LG that arise from or relate to the product or this limited warranty must be resolved by binding arbitration, not in court. - You and LG waive the right to a jury trial and to participate in a class action. - An individual action may be brought in small claims court, but not as a class or representative action.
Before arbitration If you want to start arbitration, you must first send LG a written notice at least 30 days in advance. The notice must include: - your name - address - telephone number - the product involved - a description of the claim - the relief you are seeking
Send the notice to: LG Electronics USA, Inc. Attn: Legal Department- Arbitration 111 Sylvan Avenue, Englewood Cliffs, NJ 07632
LG and you then have 30 days to try to resolve the dispute in good faith before arbitration starts.
Arbitration process - Arbitration is handled by the American Arbitration Association (AAA). - It is heard by a single arbitrator under the AAA Consumer Arbitration Rules in effect when arbitration begins. - If the AAA rules conflict with this warranty section, this warranty section controls. - The Federal Arbitration Act governs this arbitration provision. - Judgment on the arbitrator’s award may be entered in a court with proper jurisdiction. - The arbitrator decides all issues except the scope and enforceability of the arbitration provision, and whether a dispute is arbitrable; those issues are for the court.
Fees, hearing, and location - You do not need to pay a fee to begin arbitration. - LG will promptly pay AAA filing fees unless you seek more than $25,000 in damages; after that, AAA rules control fee payment. - LG pays AAA filing, administration, and arbitrator fees for qualifying arbitrations under the rules stated here. - If you prevail, LG will pay reasonable attorneys’ fees and expenses, considering factors such as the purchase amount and claim amount. - If the arbitrator finds your claim or requested relief frivolous or brought for an improper purpose, fee payment follows the AAA rules and you agree to reimburse LG for amounts LG paid that are otherwise your responsibility. - If LG prevails, LG waives any right to seek attorneys’ fees and expenses from you, except as otherwise provided. - If your claim is $25,000 or less, you may choose a document-only arbitration, a telephonic hearing, or an in-person hearing under AAA rules. - If your claim exceeds $25,000, the AAA rules determine whether a hearing is available. - In-person hearings are held in the federal judicial district where you reside unless you both agree otherwise or agree to a telephonic arbitration.
How to opt out You may opt out of this dispute resolution procedure.
To opt out, you must notify LG no later than 30 calendar days from the date of the first consumer purchaser’s purchase by either: - emailing optout@lge.com with the subject line “Arbitration Opt Out”, or - calling 1-800-980-2973
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 using LG’s model and serial number lookup page.
You must opt out by email or telephone only; no other notice method works. Opting out does not affect warranty coverage. If you keep the product and do not opt out, you accept the arbitration terms.
