Customer Questions and Answers for Dishwasher Main Control Board by Bosch

Eric,

The control module will be located at the lower right side of the tub. You will have to pull the unit out from installation to access it. As for the unit running all the time the first thing that you will want to check is, make sure that there is not a leak under the unit. Remove the water valve and put a dry towel in the opening and dab it on the bottom of the pan. Pull it out and if it is wet then there is a leak and the flood switch is active causing the pump to run. If this is not the case then the control module would most likely be the cause of the failure.
