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.
FAQs
Error Messages
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 it off, turn on the washer, then press and hold the
button that has Control Lock on or under it for 3 seconds .
Q: Where should I pour the 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 or powdered color safe bleach should be put
directly into the drum. These products can be put in the empty drum before loading or on top of the
laundry after loading the washer.
Problem Possible Cause & Solution
IE
INLET ERROR
Water supply faucets are not fully open.
• Make sure that the water faucets are fully open.
Water inlet hoses are kinked, pinched, or crushed.
• Make sure that 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 MAINTENANCE .
Water supply pressure to faucet or house is too low.
• Check another faucet in the house to make sure that 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 flow is too low, contact a plumber to have the water supply lines repaired.
Water supply connected with leak-limiting hoses.
• The use of hoses designed to limit leaks is not recommended. Leak limiting hoses can trip
falsely and prevent the washer from filling.
