Bosch Dryer Error Code F:08

F:08 indicates a cable break or short circuit in the NTC door sensor circuit. The NTC door sensor monitors temperature near the dryer door and communicates that information to the control board via its resistance value. When the board detects a resistance reading outside the expected range, it triggers F:08 and stops the dryer. The fault points to either the sensor wiring, the connector plug, or the sensor itself.

No, you should not continue using the dryer while F:08 is active. The NTC door sensor provides temperature data that the control system relies on to prevent overheating. Operating the dryer without a functioning sensor removes an important safety check and could create a fire or overheating hazard. The dryer should remain off until the fault is diagnosed and resolved.

If the fix is simply reseating a loose connector or repairing a wire, costs may be limited to a service call fee, typically in the range of $75 to $150 depending on your location. If the NTC door sensor needs replacement, parts and labor combined generally fall in the range of $100 to $250. Costs can vary based on the specific Bosch dryer model, parts availability, and local labor rates.

A knowledgeable DIYer can begin by inspecting the NTC door sensor cable and plug for visible damage, pinching, or loose connections, which requires no parts and no special tools beyond a screwdriver. If the wiring looks intact, testing the sensor's resistance with a multimeter can confirm whether the sensor has failed internally. Replacing the NTC door sensor is a moderately straightforward repair, but if you are not comfortable working inside appliances, a qualified technician is recommended.

A power reset may temporarily clear the fault display, but F:08 will return if the underlying problem with the NTC door sensor wiring or the sensor itself has not been repaired. Running the built-in test programme after a reset can help confirm whether the fault is persistent. A permanent fix requires inspecting and repairing the cable, plug contacts, or replacing the NTC door sensor.
