Default Dishwasher motor problem?
Model Number: KUDR24SEAL1   Brand: Kitchen Aid   Age: More than 10 years   

Appliance Parts from AppliancePartPros.com


Hi,

I'm trying to fix my dishwasher. The dishwasher doesn't advance beyond the wash cycle on it's own. The tub fills with water, the heater heats the water, but the water doesn't get distributed to the rest of the chamber. Moreover, water is left in the tub after the cycle is canceled. Same if just the rinse cycle is used.

After eliminating the possibility of a problem with the air gap, I checked the continuity of the contacts on the motor. They all are fine.

Does anyone have any suggestions? Is the motor the problem? Could it be the control board?

Thanks for any help,

Remove the toe panel and check if the motor will work while the control calls for wash or drain. Post the results.

Here are the breakdown diagrams and Replacement parts for Whirlpool KUDR24SEAL1 UNDER COUNTER DISHWASHER | AppliancePartsPros.com

Hi Gene,

Thanks for the suggestion. The motor does not turn on. The service manual indicates the control panel may be inoperable. The panel is responsive and the led's light up. Do you think its worthwhile to check the pin connections?

Thanks,

Did you see any signs of water leak on the motor? If you did, then the pump & motor assembly has to be replaced.

Otherwise unplug the wire harness from the motor and measure the voltage between the Violet & the Blue and the Violet & the Yellow wires wile the control calls for wash.

Post the result.

Gene.

Hi Gene,

No water leaked on the pump or anywhere else.

I tested continuity in the the pump wires between violet and blue, grey, and yellow -- all were good. So I checked for 110V AC across the red-black (P10) and blue (P3), grey (P5), and yellow (P4) on the circuit control board (while in the post fill segment of the wash cycle) -- I didn't detect any voltage. However, I did see voltage across red-black (P10) and white (P7), and blue-black (P9).

Is it conclusive that the circuit is malfunctioning? Any ideas what might have gone? If I can, I'd like to be able to replace just a small electronic component rather than the whole electronic circuit board.

Thanks for your suggestions.

Sounds like the problem is a bad control board. I understand that you would like to fix the original part instead of buying the new control board but, unfortunately, Whirlpool does not provide any instructions on how to diagnose and repair it.

- The control board Part number: 8051136

Part number: 8051136
