Error Code: E11 Difficulty: Hard
Problem: Fault with the thermostat or temperature sensor (NTC Thermistor).
How to Fix E11 Error (Step-by-Step)
- Disconnect the dishwasher from power and water. Turn off the circuit breaker for the dishwasher and shut off the water supply valve, usually located under the sink.
- Pull the dishwasher out from under the counter. You may need to remove the mounting screws that secure it to the countertop or cabinets first.
- Carefully tilt the dishwasher onto its back to access the components underneath. Place a towel down to protect the floor and the appliance.
- Locate the temperature sensor (NTC thermistor). It is typically found in the sump area at the bottom of the tub or attached to the heater assembly.
- Disconnect the wire harness from the old sensor. The sensor is usually held in place by a clip or a small turn-to-lock mechanism. Remove it from its housing.
- Install the new temperature sensor, 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 power and water supply before testing with a wash cycle.
- Turn the appliance off, wait about 2 minutes, then turn it back on.

What to Check Next on This Bosch Dishwasher
temperature or heating fault: This code path generally needs temperature-sensing and heating checks, not a reset-only answer.
- Power the dishwasher off before checking harness connections at the heater, temperature sensor, and control area.
- Confirm the dishwasher fills and circulates, since the heater may be disabled if water movement is not correct.
- If the code returns, test the NTC/temperature sensor, heater circuit, wiring continuity, and control output in that order.
If the symptom returns after these checks, use the full Bosch model number from the door tag before ordering any part. The same display message can point to different parts depending on the exact model and what the dishwasher does during fill, wash, drain, or dry.
Still Not Working?
