Possible Causes
Excessive detergent causing foaming, faulty foam detection via pressure sensor, blocked pressure hose, control board misinterpretation
How to Fix / Troubleshooting
Safety first: Unplug if you need to open panels.
- Reduce detergent: Use high-efficiency detergent and follow the dosage recommended for Bauknecht washers. Overdosing is a common cause.

- Clean pressure system: As in F04, ensure the pressure hose and chamber are clean.
