Bosch Dishwasher Error Code E11 — NTC Sensor Fault
What this means
The E11 error indicates the NTC (Negative Temperature Coefficient) sensor — which monitors water temperature — has an open circuit, a short circuit, or is reading outside its expected range. Without proper temperature feedback, the dishwasher cannot regulate heating.
Step-by-step fix
3 stepsPower cycle the dishwasher
Turn off the breaker for 5 minutes and restart. The sensor may have had a temporary communication glitch.
Temperature sensor errors sometimes appear after a power surge.
Check sensor wiring
Unplug the dishwasher and inspect the wire harness connecting the NTC sensor to the control board for loose, damaged, or corroded connections.
Moisture near the sensor connection point is a common cause of intermittent errors.
Test the NTC sensor
Use a multimeter to measure sensor resistance. At room temperature, it should read approximately 50,000 ohms. In warm water, the resistance should decrease.
If resistance does not change with temperature, the sensor is faulty.
When to call a professional
NTC sensor replacement is a straightforward repair. Call a pro only if the wiring harness is damaged.
