What F10 actually means
The control board has found a fault in its own door-lock switching circuit, so the machine stops rather than run with a lock it can't control.
The board uses an electronic switch (a triac) to send power to the door interlock. On F10 that switch is reading as short circuit — in other words stuck closed — so the board can no longer be sure it is safely controlling whether the door is locked or released. The fault for this platform points straight at the control board rather than at the door lock itself, and the cycle will typically stall part-way or refuse to start at all.
What F10 looks like on a Blomberg washing machine
Most people find this page having searched for what the machine is doing rather than the code itself. On a Blomberg washing machine, F10 usually shows up as one or more of these:
- Machine door won't open
- Door won't lock or click shut
- Door lock light flashing
- Door stuck shut with the load inside
- Won't start even with the door closed
- Noisy fan
- Not getting cold evenly
- Cuts out after a few minutes
Recognise any of those? That is this fault, and the rest of this page explains what causes it and what you can check yourself.
What usually causes it
- A failed door-lock switching circuit on the main control board — the usual outcome
- Water or damp reaching the board area
- A damaged or chafed wiring loom between the board and the door lock
- An electrical surge or spike that has damaged the switching component
What you can safely check yourself
Work through these in order. Anything beyond this — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the machine plugged in.
- Turn the machine off at the wall for a minute, then switch back on — this clears a one-off glitch and tells you whether the code is permanent
- Make sure the door is shutting fully and squarely and that nothing is trapped in the seal, as the machine also flags a jammed cover in this area
- Check no laundry is caught between the door and the drum, preventing a clean close
