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.

or on top of the laundry after loading the machine.
