Start the
Rinsing
programme in order to clean the wash
cabinet.
Then reprocess the load again.

tolerance
The wash pressure differs from the reference value.
Possible causes of fluctuations in the wash pressure
include:
- Defective water connections,
- Open adapters,
- Foam build-up.
Identify and resolve the cause of this.
