OPERATION OPERATION Before Use 5 • Default settings for the selected cycle can be changed, if desired, using the cycle modifier and option buttons. WARNING • To reduce the risk of fire, electric shock, or injury to persons, read the SAFETY INSTRUCTIONS before operating this appliance. Operation Overview 1 Sort laundry and load the washer. • Not all modifiers and options are available on all cycles. A different chime sounds and the LED does not light up if the selection is not allowed.
OPERATION 17 Sorting Laundry • Use the Bedding cycle for buoyant or nonabsorbent items such as pillows or comforters. Failure to follow this caution can result in leakage. Grouping Similar Items Mixing different fabric types and/or soil levels can result in poor wash performance, color transfer, discoloration, fabric damage or linting. Fabrics should be sorted into groups as described below. • Clothing or articles that are waterproof or water resistant must be washed in the Waterproof cycle only.
OPERATION Loading the Washer General Tips • 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 of clothes. • Pretreat heavily stained areas for best results. • Brush off heavy soil, dust, and hair from items before washing. Excess dirt or sand can abrade other fabrics and lead to poor wash performance. • Combine large and small items in the tub. Load large items first.
OPERATION 19 Adding Cleaning Products About Detergent Use • HE detergents produce fewer suds, dissolve more efficiently to improve washing and rinsing performance, and help to keep the interior of the washer clean. Using detergent that is not HE may cause oversudsing and unsatisfactory performance which could result in error codes, cycle failure, and washer damage. • Detergents designated as HE-compatible may not provide optimal results.
OPERATION • If you use a detergent that does not dissolve easily or a detergent with high viscosity, it will leave a residue and clog the dispenser. Fabric Softener Compartment This compartment holds liquid fabric softener, which is automatically dispensed during the final rinse cycle. • Do not exceed the maximum fill line. Using too much fabric softener may stain clothes. • Dilute concentrated fabric softeners with warm water.
OPERATION 21 3 Carefully pour the pre-measured amount of bleach directly into the bleach dispenser. • Never add powdered bleach to the liquid bleach dispenser.

OPERATION 23 Time and Status Display • When a cycle is selected, the default time for that cycle is displayed. This time will change as modifiers or options are selected. • If the display shows ---, then the time will be displayed after the load sensing has detected the load size. • The time shown is only an estimate. This time is based on normal operating conditions. Several external factors (load size, room temperature, incoming water temperature, etc.) can affect the actual time.
