Error Code: E13 Difficulty: Hard
Problem: The water temperature is too high (above 75°C).
How to Fix E13 Error (Step-by-Step)
- Disconnect the dishwasher from power by unplugging it or switching off the circuit breaker. Turn off the water supply valve, usually located under the sink.
- Carefully pull the dishwasher out from under the counter. You may need to disconnect the drain hose and water inlet line from the house plumbing first. Have a towel ready for any water that may spill.
- Gently lay the dishwasher on its back to access the bottom panel. Locate the NTC temperature sensor, which is part of the heater assembly at the base of the tub.
- Disconnect the wire harness connected to the sensor. Note the orientation of the wires before disconnecting.
- Remove the old sensor. It is typically held in place by a clip or by twisting it out of the heater assembly. Be prepared for a small amount of water to drain out.
- Install the new NTC sensor (part 00165281), ensuring it is securely seated and the O-ring creates a good seal. Reconnect the wire harness.
- Carefully set the dishwasher upright, slide it back into place, and reconnect the water supply and drain hose. Restore power, then run a test cycle to ensure the error is resolved and there are no leaks.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
