Error code E02 on a Blomberg washing machine typically indicates a problem with the water filling process. It could be due to blocked filters, a kinked hose, or a problem with the water supply.
To fix this, follow these steps:
1. Check if the filters at the water inlet are clogged. If so, clean them.
2. Ensure that the inlet hose is not kinked or bent.
3. Check the water supply to ensure it is turned on and has adequate pressure.
4. If the problem persists, it may be an issue with the water inlet valve or the pressure switch, in which case you may need to contact a professional for repair or replacement.
