My kenmore elite #23022 is about 10 yrs old and has started knocking during the spin cycle. About 1 knock per revolution. Any ideas?
:confused:

The basket is off center or off kilter and needs to be rebalanced. The knock you hear is the basket crashing into the side of the wash drum.

I know you will think this is a weird question but is your drain hose sealed into the drain pipe?
