The E01 error code in a Blomberg washing machine indicates an issue with the door lock. The washing machine is not able to lock the door properly or cannot verify if the door is locked. To fix this problem:
1. Check the door: Ensure that the door is properly closed. If not, close it properly and try starting the machine again.
2. Inspect the door lock: If the door is closed properly but the error persists, there may be a mechanical issue with the door lock. In such a case, you may need to replace it.
3. Check for obstructions: Sometimes, a small piece of clothing can get stuck in the door, preventing it from locking. Make sure there is nothing obstructing the door.
4. Call a professional: If the error still persists, it's best to call a professional to diagnose the problem. It could be an issue with the electronic control board.
