OPERATION

Using the Washer

1. Sort Laundry and Load the Washer

Sort laundry by fabric type, soil level, color and load size, as needed. Open the door and load items into the washer. If using detergent pods, place pod in drum before loading 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 pods in the dispenser.

3. Turn on the Washer

Press the Power button to turn on the washer. The lights above the cycle buttons will illuminate and a chime will sound.

4. Select a Cycle

Turn the Cycle Selector Knob until the desired cycle is selected. The preset Temp., Spin, Soil and option settings for that cycle will be shown. Pressing the Start/Pause button without selecting a cycle will cause the Normal cycle to begin immediately.

5. Adjust Settings

Default settings for the selected cycle can now be changed, if desired, using the cycle modifier and option buttons. • Not all modifiers and options are available on all cycles. A different chime will sound and the LED will not come on if the selection is not allowed.

6. Begin Cycle

Press the Start/Pause button to begin the cycle. The washer will agitate briefly without water to measure the weight of the load. If the Start/Pause button is not pressed within 60 minutes, the washer will shut off and all settings will be lost.

7. End of Cycle

When the cycle is finished, a melody will sound. Immediately remove your clothing from the washer to reduce wrinkling. Check around the door seal when removing the load for small items that may be caught in the seal.

NOTE

• The washer rotates the laundry in a way that allows it to use less water while still fully saturating your clothing. It is normal to not be able to see water during the wash cycle.
• If the temperature or the water level inside the machine is too high, the door will not unlock when the Start/ Pause button is pressed. To open the door in these circumstances, press Add Garments. To stop a cycle and drain the water completely, turn the power off, then on, and then press Rinse+Spin.

Loading the Washer

• Check and empty pockets. Paper clips, coins, matches, etc. 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.
• Combine large and small items in a load. Load large items first. Large items should not be more than half of total load.
• The washer can be fully loaded, but the drum should not be tightly packed with items. The door of the washer must close easily.
• Do not wash single small items. Add 1-2 similar items to the load to prevent an out-of-balance load.
• Wash thick, bulky items individually. Heavy blankets, comforters, bedspreads, or pet beds can get tangled or cause an unbalanced load if combined with other items.
• Do not wash/spin waterproof items. Washing raincoats or sleeping bags may result in abnormal vibration or may cause the load to bounce, which could damage the drum.
• Wash small, light items in a mesh bag. Items like underwear can get caught in the door seal, and a brassiere hook may damage other items or the drum.
• 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.
• For best performance, load clothes as shown.

- Load clothes loosely, and do not overfill the drum. Clothes need room to circulate in order to get clean.

- Do not press down on items while stacking them in the drum.

TROUBLESHOOTING

FAQs: Frequently Asked Questions

Q: Why does my washer make loud banging noises while it is filling with water?

A: This is actually a problem with the plumbing in your home. When the water valve in the washer shuts off, it can cause pipes in your home to move, resulting in a loud banging noise. This effect, called water hammer, can be reduced by installing an item called a water hammer arrestor. Add-on arrestors can be purchased through your local hardware or home improvement store.

Q: Why is there so little water in my washer? How can it clean the clothes?

A: HE (High-Efficiency) washers are designed to properly wash your laundry while using a minimum amount of water and energy. Because the water volume is low, the small amount of detergent used is more concentrated in the water, resulting in excellent cleaning performance.

Q: When I press a button, why does my washer beep and then nothing happens?

A:

• The Control Lock feature is turned on. To turn off Control Lock, turn the washer on, then press and hold the button that has "*Control Lock" on or under it for three seconds.
• Power or Signal is off.

Q: Where should I pour my OxiClean™ or other powdered laundry products when doing my laundry?

A: If you are using powdered laundry detergent, load it in the main detergent dispenser after removing the liquid detergent insert. Powdered laundry agents such as OxiClean™ or powdered color safe bleach should be put directly into the tub. These products can be put in the empty tub before loading or on top of the laundry after loading the machine.

Before Calling for Service

The washer is equipped with an automatic error-monitoring system to detect and diagnose problems at an early stage. If the washer does not function properly or does not function at all, check the following before you call for service.
