Hi Guru guys,
I have a Bosch SHE43M05UC/48 dishwasher that was installed in the house I purchased three years ago. It has been working perfectly until recently, when the machine would suddenly shut off mid-cycle and trip the circuit breaker at our breaker box, which is a line dedicated exclusively to the dishwasher.
Originally since there was water in the bottom of the unit, I assumed the drain pump was faulty. Using the excellent information you all have here, I ordered a new drain pump and sucessfully completed replacement of it. Sadly, I discovered that the problem was not resolved, and it appears that both my new and old drain pumps work fine, as water does indeed drain at the beginning of the cycle.
From an electricity standpoint, it certainly seems like tripping the circuit breaker would mean that there is a short-circuit happening somewhere in or around the unit during the cycle. However, I removed the bottom panel and access panel of the dishwasher, checked all the drain lines for blockage, cleaned everything as best I could, but I could not see any leaking water with my naked eye.
I have not gone so far as to remove the Heating Element, and a Google search for another dishwasher that shuts off mid-cycle seemed to suggest that this could be at fault. I am unsure whether a bad Heating Element would cause my circuit breaker to trip, however.
Can you geniuses help me? I have fixed dishwashers in the past and I DON'T want to let this thing beat me!! If I have to order a new appliance I will but I would hate to do that if I can just figure out what is needed to repair this unit, order a part, and replace it.
