What Does Error F9 Mean?

The Miele Oven F9 error code indicates a malfunction related to the PT1000 temperature sensor, often resulting in the oven failing to heat properly. Users may hear an unusual buzzing sound, and the control panel will display the F9 error. This issue typically arises from an open circuit in the temperature sensing circuit, which may require inspection or replacement to restore normal functionality.

Common Symptoms:

  • Error F9 displayed on oven control panel
  • Oven may stop heating or will not operate normally when the fault is present

Possible Causes

  • PT1000 temperature sensor open circuit / sensor fault (medium)

How to Fix Error F9

DIY Fix Basic user-level checks for temperature sensor related errors

  1. Turn off the oven and disconnect it from power for safety before inspecting components.
  2. Visually inspect the oven interior for obvious damage or debris that might affect sensor wiring (e.g., food debris near the sensor).
  3. Reconnect power and attempt a restart of the oven to see if the error clears (power reset can clear transient faults).

Technician Only Diagnose and repair PT1000 temperature sensor circuit

  1. Disconnect power and remove oven access panels to reach the PT1000 temperature sensor and its wiring harness.
  2. Using a multimeter, measure the resistance of the PT1000 sensor; compare against expected resistance at ambient temperature according to service specification.
  3. Inspect wiring harness and connector for damage, pin corrosion, or loose connections; repair or replace as needed.
  4. If sensor and wiring are intact but error persists, test the oven control board’s sensor input circuit for faults and replace the failed component if required.

Parts needed: PT1000 temperature sensor, Wiring harness/connector, Control electronics (if sensor input circuit is faulty)

🛑 When to Call a Pro:
  • If you cannot safely access or test the temperature sensor wiring or control board.
  • If resistance readings of the PT1000 sensor are outside of specification and you are not trained in component replacement.
  • If wiring appears damaged near mains or control electronics.
