Question about Bosch 24 in. SHU43 Built-in Dishwasher
Our Bosch SHU43C Built-in Dishwasher continues to run after the dishwasher has completed all of its cycles. The dishes are clean and dry, the timer reads 0 minutes remaining, and the "sanitized" light comes on, but we can still hear it running until we shut it off using the power off button. We have tried Finish Jet-Dry dishwasher cleaner (twice) on the recommendation of the Bosch people, who told my wife that the sensor may be getting fooled by a build up, but that did not fix the problem.
I have the same dishwasher and started experiencing the same problem last week. It is now fixed (at least for the moment). Here's what I did first. I checked the drain pan under the machine for water(none), the heater for continuity(okay), the float for binding(none), and the float switch for proper functioning(okay). I tried turning the ckt breaker off for a couple of hours to see if that would reset the control module(no effect). I then dissasembled the front door and removed the control module. I had previously read about the common problem of a cold solder joint on the heater relay pin on the control board. My heater was working and the joint looked good but I resoldered it anyway. I reassembled everything and it worked perfectly! My conclusion is that it was either a cold solder joint that was somehow causing the problem or a connector issue that got resolved during my disassembly/reassembly. Hope this helps.
