What Causes My Whirlpool Duet Washer to Knock During Its Spin Cycle?

Metal Items

• When you wash items that have metal buckles, buttons, zippers and other pieces, you can expect to hear noise from the washer. The more of these items there are in the washer, the more noise you can expect. As the washer spins, the laundry will hit up against the washer drum. When the metal pieces make contact with the drum, you can hear a knocking, rattling or even a scraping metal noise.

Overloaded Washer

• If you cram too much laundry into your Whirlpool Duet washer, it can overload the machine. When this happens, the laundry can get twisted up together and form into a ball. As the wash tub spins, the clumped laundry can ricochet off the sides of the machine. This can result in a knocking or banging sound.

Floor Not Sturdy

• The ideal surface for a washer to sit on is concrete, but other sturdy floors can suffice. If you have the washer sitting on carpet or another surface that is not sturdy or solid, it can result in knocking noises from the machine. Inserting a piece of plywood under the washer is often enough to make the surface sturdy and solid.

Not Level

• When the washer is not sitting completely level on the floor, it can rock and shake back and forth in the laundry room. This vibrating can sound like a knocking noise if the washer is rattling up against the dryer or another surface. Adjusting the four legs of the washer with a wrench will get the machine level and eliminate the knocking.
