No final spin on old Kitchenaid KAWE560W washer
I have an old Kitchenaid KAWE560W washer that is having a problem with the 'Normal load' final spin cycle. Lifting the lid during this cycle it's obvious that the drum isn't spinning. If I then close the lid, the drum starts spinning. Alternately, I can wait for the cycle to end (close will be dripping wet), then turn the dial back to this spin cycle and it'll start right up.
Yesterday I ran a couple of loads and checked to see if all the cycles were working. The agitator is working correctly (I recently replaced the agitator dogs), and all the rinse/spin cycles other than the last one are also fine.
I'd be most grateful if someone can help me diagnose the problem and suggest what part(s) are needed to fix this washer (Sears equivalent parts are fine because I have a Sears parts store nearby). Thanks!
