Common Symptoms
- Dishwasher has no apparent power or becomes unresponsive
- Dishwasher stops mid-cycle
- Wash, drain, or dry functions do not operate correctly
- Control buttons or cycle selections do not respond
- Dishwasher does not drain or fill when other related components and wiring test good
Check Before Replacing
- Confirm the dishwasher model number and compare it with the part listing before replacement.
- Check for displayed error codes and follow the model-specific service or diagnostic procedure; an error code does not by itself prove the control board is defective.
- With power disconnected, visually inspect the board and wiring harnesses for burnt areas, corrosion, loose connectors, or damaged wiring.
- Confirm the door latch or door-switch function and user-interface operation before condemning the main board.
- If the dishwasher is completely dead, have a qualified technician verify power reaches the appliance and control board before replacing the board.
Pro Tip
A control-board symptom can be caused by the door switch, user interface, wiring, power supply, or another load. Rule out those conditions before replacing the board.
