Miele Dryer Error Code F1

F1 on a Miele dryer indicates a short circuit in the heater bank temperature sensor circuit, designated 2R30. The control board is reading a resistance level that corresponds to a temperature above 480 degrees Fahrenheit (250 degrees Celsius), which is outside any normal operating range. The dryer shuts down to prevent potential damage until the fault is resolved.

No, the dryer should not be operated while the F1 fault is active. The error indicates the heater bank temperature sensor circuit is compromised, which means the control board cannot reliably monitor heater bank temperature. Operating the dryer without a functioning temperature sensor removes an important safety check and could allow the heater to operate in an uncontrolled manner.

Cycling power to the dryer may temporarily clear the F1 code, but the fault will return as soon as the control board reads the sensor circuit again and detects the short circuit condition. A reset does not address the underlying wiring or component failure. The sensor circuit must be inspected and the short circuit corrected before the error will clear permanently.

A knowledgeable DIYer can begin by unplugging the dryer and inspecting the wiring harness and connector plug of the 2R30 sensor for visible damage, corrosion, or shorts. If a damaged wire or corroded connector is found, those can sometimes be repaired without purchasing parts. However, if the sensor itself has failed internally, replacing the 2R30 sensor requires disassembling part of the dryer cabinet and working near the heater assembly, which many homeowners prefer to leave to a qualified technician.

Repair costs vary depending on the root cause. If the fault is a damaged wire or connector that can be repaired without new parts, a service call labor charge is typically the primary expense, often ranging from $100 to $200 depending on your area. If the 2R30 temperature sensor needs replacement, parts and labor combined can range from $150 to $350 or more, depending on local labor rates and parts availability.
