Miele F25

Miele error code F25 indicates: The oven does not reach the selected temperature or significantly exceeds it, resulting in incorrect cooking and display of code F25..

The primary root cause for Miele code F25 is: A significant and persistent difference is measured between the set temperature and the actual temperature. This may be due to an out-of-calibration probe, a faulty heating element or a regulation problem on the control board..

To resolve error code F25: Turn off the oven. Check the accuracy of the temperature probe (resistance at room temperature). Inspect all heating elements. If everything is correct, the fault probably lies in the control board.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Miele code F25 persists, the physical component causing A significant and persistent difference is measured between the set temperature and the actual temperature. This may be due to an out-of-calibration probe, a faulty heating element or a regulation problem on the control board. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
