Pederl,

Yes,

Some WP dishwashers have a separate drain pump, but they all have a wash motor/pump assembly.

I get the impression that the motor never runs, no hum, no nothing, when it should be washing, correct ?

If you can get us a proper model number, we'll be more than happy to supply you with as much information as possible.

Thanks,

:) :) :)

Pederl,

Sounds like you tested the motor winding, you' d have a resistance reading, if you did it correctly. So you're on the right track.

Let's try and simplify this.

Disconnect the motor wire harness from the wash motor/pump, Program the unit to run and let fill,

1 or 2 minutes after the fill is finished, you need to check for 120 VAC from the purple wire in the harness to chassis ground. if the relay on the control board closes and the wiring is proper,you should have it.

That way we can isolate where the problem is, the control or the wash motor.

Pederl,

If you have the voltage on the purple wire, your control board is working, your wire is good, and you'd have a bad motor.

No voltage on the wire terminal would indicate a broken wire or a bad K1 relay on the control board.

And once you determine where the voltage is or isn't you can determine which way / part you will need.

:cool: :cool: :cool:

Pederl,

My diagram shows a purple wire, you may have a red/black ?

But yes, you can check the wire coming from the relay to the motor, to chassis ground for 120 VAC.

The readings and results should be the same.

:cool: :cool: :cool:

Yes, you have to unplug the wire harness going to the motor, re apply power to the unit and start a cycle, let it fill and wait 60 to 90 seconds. Then do the voltage test, on the wires in the harness, not the motor.
