Miele Oven Error Code F06

F06 indicates that the oven's Pt1000 temperature sensor circuit is open, meaning the control board is not receiving a valid signal from the cavity temperature sensor. This can be caused by a loose plug connection at the electronic module, a broken wiring harness, or a failed sensor element. The oven will typically disable heating when this fault is active to prevent uncontrolled temperature conditions.

You should not attempt to use the oven while F06 is active. Because the control board cannot monitor cavity temperature through the sensor, it cannot regulate heat safely. Continued operation without a functioning temperature sensor risks overheating and potential damage to the appliance or surrounding cabinetry.

Repair costs vary depending on what component has failed. If only the plug connection needs reseating, there may be no parts cost and minimal labor. Replacing the Pt1000 temperature sensor itself typically involves parts costs in the range of $40 to $150 depending on the model, plus labor if a technician is needed. A wiring harness or control board replacement would increase total repair costs significantly, potentially ranging from $200 to $500 or more.

The first step, checking that the sensor plug is properly seated at the electronic module, is something a confident DIYer can attempt after disconnecting power to the oven. If the plug is secure, testing the Pt1000 sensor with a multimeter requires basic electrical knowledge but is manageable without professional tools. However, if the sensor, wiring harness, or control board needs replacement, a qualified appliance technician is recommended for safe and accurate repair.

A power reset by switching off the circuit breaker or unplugging the oven may temporarily clear the displayed code, but the fault will return immediately if the underlying problem has not been fixed. The error is triggered by a real circuit condition, so it will persist or reappear until the open-circuit fault in the sensor, wiring, or connector is corrected.
