Check the door latch and switch: Open the dishwasher door and inspect the latch for any visible damage. Use a multimeter to test the door switch for continuity. If faulty, replace the door latch or switch.
-
Inspect the control board: Unplug the dishwasher and remove the control panel. Check for burnt components or loose connections. If damaged, replace the control board.
-
Test the heating element: Use a multimeter to check the resistance of the heating element. If it reads infinite resistance, it needs to be replaced. Ensure the dishwasher is unplugged before testing.
