I came home from vacation and found the lights out on the dishwasher. It worked fine before I left. I've verified AC power to the dishwasher, AC power to the door latch, and AC power out of the door latch to the circuit board.

The circuit board does not show any heat stress or damage of any kind.

How do I verify that the circuit board is the faulty part before I replace it?

The PCB says Solectron P/N MAY6917664.

Try checking power ground continuity to the module, usually a white wire.
