I've got a 4 year old WFW9500TW01. It fills and agitates just fine, and goes through the timer down to zero, but doesn't seem to spin during the automatic wash modes. So I just get a pile of very damp clothes at the end of the cycle.
I can get the washer to spin, if I put it in the Drain/Spin or Rinse/Spin mode once the wash cycle is completed. This makes me think the spin motor, direct drive or belt are OK?
Reading through previous posts here: I did check the drain and hose - not plugged. The drain motor does spin when I supply voltage to it. When I put it in diagnostic mode (the one where you put it in spin mode, press Rinse/Hold four times) it goes through all the cycles without a glitch, no error codes. Funny thing is, I can't get it to give me an error history (the one where you have machine off, then push any button 5 times) - the screen just stays blank.
Does this mean I have to get a new Motor Control Unit? I'm by no means an appliance repair person, but this is as far as I've been able to troubleshoot it.
