Josh G. for Model Number Bosch SHU33A The dishes on the bottom rack don't seem to be getting clean, with actual food particles (which are soft and wipe off) being left on them. I cleaned the bottom spray arm, and also ran the dishwasher for a minute without the spray arm. I wanted to see if the arm is moving, so I let it run a bit and opened the door really fast. It looked like the water coming out of the holes in the arm was only coming up about six inches or so. I guess I figured the water would be coming out much faster, like with a high pressure type velocity. How much water should be coming out, and how would I check it? I've read about circulation pumps, and restricted circulation pumps. Any way to find if that is the case? What do you think? Thanks.
Answer Hi. Remove the top filter screen part # 00441905 and the micro basket part # 00615079 to see if it is not clogged as well. Remove the circulation pump part # 00239144 to dislodge any debris clogged in the impeller blade from turning. Circulation Pump Repair Kit part # 00167085. If the impeller spins loose on the shaft then you will not get high water spray levels desired. The manufacturer does not give us a wash arm gpm or pressure output measurement value. IF the impeller is clogged or damaged then it will not allow the full internal water pressure to circulate. Thank You. Read More... Answered by AppliancePartsPros.com | Tuesday, November 13, 2012
