Don for Model Number SHX46A06 My Bosch SHX46A06 dishwasher fills to the level of the upper holes in the filter basket. I believe this is correct. The Circulation pump starts running, but water is only coming out of the lower arm about 2". I ran cancel/drain cycle and water drained, then I vacuumed the remaining water out. Removed screw and cover over drain pump impeller and vacuumed more. The impeller turned fine. Measured circulation pump resistance of 12 ohms, starter winding resistance of around 20 ohms, and checked the starter capacitor with ohmmeter, saw resistance start out at low value (less than 100 ohms) and increase up to hundreds of k ohm. I assumed that pump and cap were good. Turned the pump by hand and it felt normal, no binding. I removed the upper and lower spray arm assemblies, cleaned them, blew air and ran water through them to assure no clogs. Then reinstalled them. Cleaned all debris out of the sump area, put impeller cover back in and started a new wash cycle. The machine started by draining for a few seconds, then it filled as I described earlier. When the circulation pump started, I observed it turning at what appeared to be a consistent and normal speed. I did NOT smell any burned winding. Measured 120VAC across circulation pump terminals and 240VAC across the starter capacitor. I have read all the posts where you recommend replacing the circulation pump. I am ready to do that but I am hoping to get some directions on how to remove it since it's not at all obvious to me. Also, given my voltage and resistance measurements and the observation of the pump spinning, I am wondering if it is possible that there is a clog at the circulation pump inlet or outlet or maybe a damaged impeller or other part within the "wet" portions of the pump. I assume that I can inspect that but am requesting instructions for how to do that as well. Lastly, when the circulation motors do fail, what is the failure mode: burned windings, worn brushes,…? When you have recommended changing the circulation pump, I haven't seen anything from folks saying that changing the pump solved their problem. Has it? Thank you very much - Don Q
Answer Hello Don. It sounds like the water level is low in the unit. I would try to replace the water valve on the unit. See if the level increases and causes the pressure to increase and work properly. Read More... Answered by AppliancePartsPros.com | Monday, July 29, 2013
