Bosch Oven Error Code F44
F44 mirrors F43 for the lower cavity of a double oven: the motorised latch never confirmed the unlocked position. As with the upper oven, a hot cavity is a normal reason; a cold, still-locked door is the fault.
Common causes
- Lower cavity still too hot to release the latch
- Lower latch motor failed or mechanism jammed
- Latch switch stuck reporting locked
- Wiring fault between latch and control board
What to check, in order
- Let the lower oven cool fully after self-clean before treating this as a fault; the lock releases only below a safe temperature.
- Cycle the power at the breaker for a minute once the oven is cold and listen for the latch motor running.
- Never force the lower door open — the latch and hinges bend easily and are expensive.
- A cold oven that stays locked needs a technician to release and test the latch assembly.
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code F44, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
