My Kenmore dishwasher fills but the motor does not turn on either wash cycle or the drain cycle. There is power to the unit, because the LEDs light up. It's not the door switch.

The Technical Data Sheet for the dishwasher (part no. 9744480) shows the wiring diagram for this unit, and shows the proper ohms for the motor wiring. I've put an ohmeter on it, and it's to specifications.

After the machine fills, there is a pause after the filling stops, then there is a "click" from the control panel as though a relay is working. Also, if you open the door, then close it, a few seconds go by before the same "click" (like a relay) occurs. Before, that was what happened when motor started. Now, there's just a click and no motor operation.

Any ideas?
