Bosch continuous run problem - different model

I have a Bosch SHX46B02UC/21 that runs constantly and never finishes. Searching the forums, this seems to be the same problem many have experienced with the SHU models, but I can’t seem to find out any info on the SHX. Does this model also suffer from the “cold solder point” on the board in the control module, or is it more likely to be the module itself or the heater assembly? Any instructions on how to run and interpret the diagnostics on this model? And, last, do you know the part numbers for the control module and heater assembly if I need to order replacements?

Thanks for your help!

Well, I decided to dig into the control module to check for the cold solder point, and sure enough, there it was. Couldn’t miss it, really - it burned so badly that there was a big scorch mark on the inside of the plastic housing and carbon all over the circuit board. I cleaned it up and put a blob of solder on the bad spot, fired it up, and I’m back in business.:slight_smile: Didn’t take more than 30 minutes start to finish. As common as this problem seems to be with Bosch dishwashers, it makes me wonder why they haven’t addressed it either through a recall or a design change…
