When running Permanent Press or Handwash/Casual cycles (slow ones) the cycle proceeds until after draining. When the Spin tries to start, it seems like the motor engages for a second, and then drops out. This repeats about every two or three seconds until the machine is shut off. It is a fairly violent action.

In Heavy or Normal Cycles everything runs fine. There is no gearbox noise. Everything is smooth and quiet. Even in the troubled cycles all goes well until attempted spinning after draining.

When running Diagnostic Test called RECIRCULATION PRESSURE SWITCH TEST this same repetetive starting/stopping occurs. Display shows Er immediately until I stop the test.

Motor resistances are ok. Both pressure switches ok. Motor Coupler still good. I can turn the input to the transmission by hand and all seems ok.

It almost seems like the logic in the controller has changed, but I don't see how that could be. Is there ever a need to reload a logic program into the control?

This does sound like a control unit problem, since the machine performs well in some cycles. Replacing the control unit is your first step.

If you need more info please post a full model number so we can see exactly what model you have.

This washer is a Kenmore Elite 110.22054102, 3 speed

Ok good, go ahead and try replacing the timer unit.

Since the core problem was that the motor would run ONLY in High Speed, I decided to replace the relays that control the speeds and direction of the motor. Those are located on the control board in the console. They are identified on the printed circuit board as K2, K3, K4, and K5. Total cost of relays was under $14. I had already replaced the Start Switch on the motor.

This solved the problem. Machine now works perfect in all cycles.
