What Does Error F04 Mean?
The Blomberg dryer error code F04 indicates an overheating issue, often linked to a malfunction in the heating element or high-temperature sensor. This error typically results in the dryer stopping mid-cycle, feeling excessively hot inside, and failing to complete drying cycles. Addressing ventilation and lint filter blockages is crucial for resolving this problem, as restricted airflow can trigger the F04 error.
Common Symptoms:
- Dryer stops mid‑cycle with error displayed
- Dryer feels very hot inside when error appears
- Cycle interruption without completion
Possible Causes
- Overtemperature / high internal temperature cut‑out (medium)

DIY Fix Check ventilation and lint filter
- Turn off and unplug the dryer.
- Clean the lint filter thoroughly.
- Ensure the external venting is not blocked and airflow is unobstructed.
- Restart the dryer and see if the error reoccurs.
Technician Only Inspect and test temperature sensor and thermal safety components
- Disconnect power and remove appropriate access panels.
- Check the temperature sensor (NTC) for correct resistance and operation.
- Inspect wiring and connectors to the sensor for damage or loose connections.
- Test thermal cut‑offs or high‑limit thermostats and replace any components that fail continuity tests.
