Bayougal for Model Number KUDP02CRWH4 My Kitchenaid dishwasher (model KUDP02CRWH4) suddenly began making a very loud buzzing noise when operating during the wash cycle. It cleans the dishes fine and is draining fine - no leaks and no unusual noises when draining. I have disassembled and cleaned the lower wash assembly, sump cover and filter, and food chopper assembly. I did find some debris which I removed and cleaned thoroughly. The impeller was extremely hard to turn when I removed the food chopper assembly. So, I flushed it out with clean water and a turkey baster. The impeller is turning now, but I feel resistance. Should this be spinning freely? Could this be the source of such a loud noise?
Answer Bayougal, Yes, the impeller having resistance could be the cause especially if the noise is a loud squeeling type noise. This would be an indicator that the bearings are going out and need to replace the motor. Read More... Answered by AppliancePartsPros.com | Wednesday, August 14, 2013
