I have a Bosch dishwasher that a customer brought to my shop from a far off rural area. It drains fine when cycle is cancelled or when I run the rinse and hold cycle. All other cycles, it fills circulates but will not drain. I am suspecting the control but the wiring diagram is not in the tray in bottom of unit, so I could be overlooking something. Craig
After reading posts here for similar problems and looking at a wiring diagram that I downloaded and printed from one of the posts (thank-you very much!) I accessed the control and found when I opened the case, it had the infamous failed solder connection at one of the relays. Repaired the connection and tested the unit on quick wash and regular wash and it worked fine. This forum was VERY helpful. Thanks again, Craig.
Hey all I found a really good video that explains what and how to fix a bosch dishwasher not draining. Click on the link below.
