E05Warning
Bosch Dishwasher E05 Error Code
The NTC temperature sensor has an open circuit, no temperature reading.
Common causes
- Broken wire or loose connector at NTC
- Faulty NTC thermistor
- Corrosion on terminals
How to fix it
- Check the NTC connector is securely plugged in.
- Measure resistance of sensor; if infinite, sensor is open and needs replacement.
- Inspect wires for breaks, especially near the sensor probe.
⚠ When to call a pro: If sensor replacement does not fix, the control board may have a fault.
