Questions & Answers

For Whirlpool Pump Diverter Motor (Part Number: OEM17966634)

Mark for Model Number Kitchen Aid KDTM404EWH3

Re: Diverter motor W10843811. Can you please tell me if the center metal shaft that turns the Dynamic Wash arm should rotate when bench testing this motor ( A/C current direct to the motor leads) The motor shown being tested does not have the metal shaft extension for turning the dynamic wash arm. The plastic covered portion of the shaft turns slowly as shown in the video to turn the diverter plate. I dont know if the central shaft should turn all of the time when bench tested or if it needs a signal from one of the other sets of input wires to activate that function. Thanks.

1 Answer

Mark, Thanks for the question!!! Yes, the output shaft of the diverter should turn when powered with 120v on the bench. If it is not turning replace the diverter.

Robert, When you pull out the rack, there should be a clip on the sides of the rack in the area of the adjusters that you would need to release in order to get the rack out of the dishwasher.

Curtis, The manufacturer did not make the seal available without the whole sump assembly. If it has leaked then you will likely need the sump assembly and the diverter motor assembly.

Hello Krash, I'm sorry but the seal is only available with the sump assembly WPW10457989. This is how the manufacturer has set up the part available.

Martin, The more common issue for failed diverter motors in your type dishwasher, is a leak around the diverter plate shaft. You may want to consider a new "sump" assembly which should include a new shaft seal, or at least check to see if the shaft seal is available as a separate part component. We would have been happy to research the available parts and supplied the parts needed, but you forgot to include a model number.

Allen, To test the diverter motor you will want to test at the main board Connector P7 across the blue wires when the unit is in the wash mode. There should be 120 vac at this point to the diverter motor. You could also check at the motor to make sure that there is 120 vac there. If there is power at both locations then the motor would be the issue.

Joseph, You do not put grease on this diverter motor or the seal for the diverter motor.
