My under counter unit lost all power in middle of the washing cycle. This has happened before and I replaced the thermal fuse assy. part # AP311 5175 to fix the poblem. This time the replacement didn’t work.
Remove the toe panel and check the power cord connection to the dishwasher for proper connection and/or burned wires.
Check for 120 VAC to the dishwasher.
Check the door switches.
