Questions & Answers

For Whirlpool Circulation Pump And Motor Assembly (Dishwasher) (Part Number: OEM15917766)

1 Answer

Marcy, it would be recommended that the motor W10428773 is tested for 120VAC during the wash cycle. If the motor is receiving 120VAC, and it is not operating, then it will need to be replaced. If the motor is not receiving 120VAC, and there is not a broken wire, then the timer WP3378579 would need to be replaced.

Dave, If there is no place on the new pump and motor assembly to install the weight then it would not hurt anything to leave it off.

Hello Jim, You should replace the entire assembly W10428773 since this initial symptom is normally caused by the seal sticking to the motor shaft. This will actually cause the unit to put water in the floor.

Jim G for Model Number Kitchen aid Dishwasher KUDV24SEBL4

I just receiv4d a replacement pump/motor for my dishwasher . Invoice # 2941504 part # AP5305919 (W10428773) The old pump had the wiring "hard wired" into the motor with a plug on the other end . The new part which I was told was OEM and totally interchangeable, needs a short 4 cable wiring harness with a plug on each end. I need that wiring harness otherwise the pump is useless. I don't mind purchasing it but your customer service could not find it. You can see what I am talking about by looking on your website at the picture of a similar pump motor part # AP5306182 (W10428168). I either need the harness or another pump motor that will work Thank you Jim Gill

Jim, You will need to order 8271507 motor harness adapter. This is one of those "unlisted" parts, that may or may not be needed, It is almost impossible to find under normal circumstances. Thanks

Hello Smith. Remove the inner door liner and see if the unit is leaking inside the door around the dispenser. If so, you will need to replace the dispenser assembly WP8052027. Hope this helps.
