What Does Error F18 Mean?

The Miele oven F18 error indicates a malfunction with the oven's temperature sensor, often leading to inconsistent heating and incorrect temperature readings. This can manifest as an error during or after heating, displaying temperatures that are much higher or lower than expected. The root cause is typically a fault or calibration error in the NTC temperature sensor, which is crucial for proper temperature regulation. To address this issue, a simple power reset may help, but replacement of the temperature sensor is generally required for a permanent fix.

Common Symptoms:

  • Oven displays F18 during or after heating
  • Apparent incorrect temperature display (very high or low compared with expected)
  • Possible failure to heat correctly due to sensor misreading

Possible Causes

  • Oven interior temperature sensor (NTC) fault or calibration error (medium)

How to Fix Error F18

DIY Fix Basic Verification and Power Reset

  1. Turn the oven off and disconnect it from power for at least 30 seconds.
  2. Reconnect power and restart the oven to see if the error persists.
  3. Observe whether the displayed temperature matches expected values during use.

Technician Only Inspect and Replace Temperature Sensor

  1. Disconnect power and remove the oven sensor (NTC) from the oven cavity.
  2. Test the sensor with a multimeter for correct resistance at known temperatures.
  3. Replace the temperature sensor with a genuine Miele part if out of range.
  4. Ensure proper seating and connection before restoring power.

Parts needed: NTC temperature sensor

🛑 When to Call a Pro:
  • If error persists after sensor replacement
  • If you are not comfortable handling internal components or live testing
