On the Main Control Board CSM

A CSM is a protective device that is part of GE Dishwashers and located on the main control board. This

device is designed to trip if current leakage to ground is above 20mA ± 5mA is detected. The CSM functions
similar to commercially available GFCIs, if tripped the dishwasher is non-responsive. Entering Consumer
Error Mode

for 10 seconds, if the door is closed. If there are active error codes logged, they will be displayed at this time.

The CSM is reset when Service Mode is entered.

The cause of tripping is likely external to the board itself. The board should only be replaced after all

other diagnostic tests have been completed and all other potential causes have been ruled out. Potential
causes of current leakage to ground could be due to water leaking onto a live component, a component
malfunction, or a fault within the wiring harness. If water caused the CSM to trip, the leak must be repaired.
