How to Troubleshoot & Replace Bosch AP3842231 / 00442548 Dishwasher Circulation Pump And Motor Assembly

Hearing a metal on metal noise and not actually circulate water cancelling cycle worked fine After some web research, I concluded it was highly likely to be the circulation pump, so I watched the video on AppliancePartPros.com and realized it was a lengthy repair (a lot of steps) but not technically difficult. I simply played and paused the video at each step and duplicated the steps. The biggest things to take note of: 1) take good pictures of the wiring to use when you re-connect. 2) Wear gloves when reaching down between the housing and the base when disconnecting or reconnect components. The sheet metal edge where the sump mounts is VERY SHARP. I cut myself several times. 3) Pay special attention to the rubber mounts used to hang the circulator pump assembly. As the unit is laying on its side with the base partially separated they have a tendency to release for their hanging positions. Make sure they are in position during re-assembly. 

The circulation pump went bad and I called the appliance parts pros and they guided me to the right part. I watched a YouTube video on how to do it. Everything went very smoothly and works great. 

Ordered pump motor assembly Friday, had it Sunday, washing dishes Sunday night. 

Ordered replacement pump, arrived quickly, watched video describing how to disassemble and remove old pump and install new pump. Took about 90 minutes- lots of steps (all well described in video), some steps were a little difficult to accomplish due to narrow spaces. It was gatifying when it was all back together, nothing leaked, and EVERYTHING WORKS AGAIN. Much better than replacing the dishwasher that we love. 

Replaced pump following instructional video 

Replaced the circulation pump. Fwiw, the initial order shipped and arrived promptly but was damaged during shipping, breaking the capacitor. Called, sent pics and they had the replacement shipped that day. Great customer service all around. 

This site was incredibly helpful with finding a replacement part and giving detailed instructions for how to change the part. It was literally a one stop shop for everything that I needed. It also suggested other parts that I needed for the job that I had not thought about ahead of time. This part fit a Siemens Dishwasher model number SL84A315UC/30 - which was not listed anywhere on the internet, Being able to do this job myself (thanks to this site) saved me over $1000. Thank you!
