Ex Wrestler for Model Number Bosch Dishwasher #SHE45M06UC/48, Drain pump #0064229 My Bosch SHE45M06UC/48 is making a grinding noise. I took the dishwasher apart and checked the circulating pump. The impeller moves smoothly and is intact and is firmly affixed to the motor shaft, so I think the circulating pump is fine. I checked the solenoid inlet valve for continuity (it was good) and mechanically (also good). I think the problem is with the drain pump but I'm only 80% sure. when I spin the impeller manually it feels like it has a detent and springs forward when spun every 180 degrees. It does not spin smoothly like the circulating pump. I plugged the drain pump into a cord I made with a standard 120V AC plug on one end, and female 1/4" spade clips on the other. The impeller would spin but seemed loud. Is the "detent" like the movement of the impeller indicative of a problem or is that the way it's supposed to be? Does the impeller on a new part #00642293 drain pump spin smoothly? Thanks
Answer Hello Ex, The "detent" as you called it is a characteristic of the magnetic fields of the type of motor in the pump. You should open the unit and use a wet vac to remove any possible glass shards, bones, or other foreign material that are common in dishwashers. These pumps give so many problems, if there are no clogs in the drain line, I would replace the drain pump 00642239. Read More... Answered by AppliancePartsPros.com | Tuesday, August 4, 2020
