Customer Question

We have a Bosch SHE44C dishwasher which has recently started having difficulties finishing the wash cycle.

Quick Wash cycle time has gone from 37 minutes to 56-58 (on display), and Regular Wash cycle has moved from 110 minutes to 121 minutes.

Repeated test cycles in both Quick Wash and Regular wash seem to indicate that the last minute ("1" on display) actually lasts several minutes - or until we cancel it.

Inlet water temperatiure is 122 degrees F. The Large Object Trap/Cylinder was slightly dirtly but cleaned before any of the tests were run. The Fine Filter was also cleaned before testing stared. The drain hose appears to be free of clogs.

I'm unsure that the water is being heated sufficiently - several dishwashing cycles appear to have used cold water. There is also an odor in the dishwasher.

Well your on the right track. There is a very common problem with this unit and it's the control board. The control board will need to be replaced because what's happening is that the relay shorts out and doesn't send enough power to th heater to heat the water to the right temperature causing the cycle to drag on. The board is about $200 but like unsaid this is very very common.

I was suspecting the control board - is this a fix that a reasonably competent DIYer can handle?

Definitely, it's located inside the door in the upper right corner. Turn the breaker off and just split the door to access the board. There are screws all around the inside liner that hold the door together.
