Possible Causes
Loose power connection in junction box, Overheating thermal fuse opening, Faulty door switch losing contact, Control board overheating
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before inspecting electrical connections.
- Inspect junction box: Check for loose wire nuts or signs of arcing. Tighten and re-secure connections.
- Check door switch alignment: Ensure the door latch fully engages and the switch is not marginally adjusted.
- Inspect thermal devices: Some models include a thermal fuse on the control board harness. Test for continuity and replace if open, while also addressing the cause of overheating.
- Ensure ventilation: Confirm the dishwasher has adequate space around it and is not tightly sealed with insulation blocking airflow to the control area.
