Dishwasher displays E13; often associated with unusually high water temperature or steam and possible odor.

Safety first: Turn off power immediately and allow the dishwasher to cool completely. Do not run further cycles until the issue is corrected.

• Inspect heater relay: Access the main control board and check the heater relay for signs of sticking or burning. If the relay contacts are welded closed, replace the control board.
• Test high-limit thermostat: Locate the high-limit thermostat on the tub base or sump. Test for continuity at room temperature and after gentle heating (per specs). Replace if it fails to open at the rated temperature.
• Check NTC sensor: Test the temperature sensor for proper resistance. A shorted sensor can cause the board to misread temperature.
• Inspect wiring: Ensure heater wiring is not shorted to ground or bypassing safety devices.
• Replace faulty components: Install new thermostat, NTC, or control board as required, then run a monitored test cycle to confirm normal temperatures.
