Possible Causes
Open heating element, Failed high-limit thermostat, Burned heater relay on control board, Loose heater wiring
How to Fix / Troubleshooting
Safety First: Disconnect power and allow the dishwasher to cool before working near the heater.
Steps:
- Visual inspection: Remove the lower access panel and inspect the exposed portion of the heating element for breaks or burn marks.
- Check continuity: Disconnect heater wires and test the element with a multimeter. An open circuit indicates a failed element.
- Inspect high-limit thermostat: Locate the high-limit thermostat (often on the tub or sump) and test for continuity. Replace if open.
- Check wiring and control: Inspect heater wiring for burns or loose connections. If the heater and thermostat are good, the control board heater relay may be defective and the board will need replacement.
- Run diagnostics: Use the tech sheet to enter diagnostic mode and verify heater operation after repairs.
