Miele Oven Error Code F06

The F06 error code on a Miele oven indicates an open-circuit fault in the oven cavity temperature sensor, designated as the Pt1000 type sensor with component reference 1R30-10. A Pt1000 sensor is a platinum resistance temperature detector with a nominal resistance of 1000 ohms at 0 degrees Celsius. When the oven's electronic control module cannot detect a valid resistance reading from this sensor, it triggers F06 and typically disables heating functions as a safety precaution. An open circuit means the signal path between the sensor and the module is broken, registering as infinite or no resistance rather than the expected value.

The fault can originate at three distinct points in the circuit: the sensor element itself, the wiring harness connecting the sensor to the control board, or the plug connection at the electronic module. If the sensor's internal platinum element has failed or its leads have broken, the circuit goes open. Similarly, corroded, loose, or improperly seated connectors at either end of the harness can interrupt the signal just as effectively as a failed sensor.

Diagnosis should begin at the plug connection on the electronic module, verifying it is fully seated and that the terminals show no corrosion or damage. If connections are secure, the sensor wiring should be inspected for breaks or heat damage. Finally, the Pt1000 sensor resistance can be measured directly with a multimeter at room temperature. A reading far outside the expected range, or an open-circuit reading, confirms sensor failure and replacement is required.
