Westinghouse dishwasher not starting? Signs of a faulty main board

The main board takes the program you select and turns it into action. It opens the water inlet valve, runs the wash and drain pumps, switches the heater and keeps watch on the sensors through every stage. When it fails, you might see a dead dishwasher with no lights, a cycle that stalls part way, a pump that won't stop running, or error codes that come and go. A faulty door switch, wiring fault or pump can mimic a bad board, so rule those out before buying an electronic part.

Fitting the new dishwasher board

Switch the dishwasher off at the wall and turn off the tap before you start. Electronic boards are static sensitive, so touch a bare metal part of the frame first and hold the board by its edges. Photograph the plugs on the old board and move them across one at a time. If you're not confident with electrical repairs, have a qualified technician fit it. Test with a rinse program to check it fills, heats and drains.
