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.
