Miele Dryer Error Code F2

F2 indicates that the heater bank NTC temperature sensor, component 2R30, has an open circuit condition. The control board interprets an open circuit as a temperature reading below 20°C, signaling that no valid thermal data is being received from the heater area. This fault is only logged after the heater has been running for at least one minute, confirming the failure is real rather than a startup glitch. The dryer will not continue operating until the fault is resolved.

Start by inspecting the 2R30 sensor, its wiring leads, and all plug connections for visible damage, corrosion, or loose terminals. Use a multimeter to test continuity through the sensor element and along the harness wiring back toward the control board. If the sensor itself reads open circuit, it will need to be replaced. If wiring or a plug connection is the cause, repairing or replacing the affected section of the harness resolves the fault.

Repair costs vary depending on whether the issue is a failed sensor, damaged wiring, or just a loose connection. A replacement NTC sensor typically falls in the range of $20 to $60 for the part alone. If professional labor is needed, total costs including diagnostics and installation generally range from $100 to $250, depending on the technician and region. Repairs involving more extensive wiring harness replacement will be toward the higher end of that range.

Resetting the dryer may temporarily clear the fault display, but the F2 code will return once the heater has run for a minute and the control board again detects the open circuit. Because the sensor monitors heat output during operation, continued use without fixing the underlying fault is not recommended. The root cause, whether a failed sensor, broken wire, or loose connection, must be corrected to permanently clear the error.

Running the dryer with an active F2 fault is not advisable. The 2R30 sensor is responsible for monitoring the temperature at the heater bank, and without a functioning sensor the control system cannot verify that heating is operating within safe limits. Miele's control logic flags the fault specifically to prevent unmonitored heater operation. The dryer should be taken out of service until the sensor circuit is inspected and repaired.
