Users may notice foam present during the cycle, and the error typically occurs shortly after starting or during detergent dispensing.
Common Symptoms:
- Dishwasher display shows F52 and programme stops
- Foam present or suspected inside dishwasher during cycle
- Occurs shortly after start or during detergent dispensing
Possible Causes
- Over‑dosage of detergent or incompatible detergent combination (high)
