Start the
Rinsing
programme in order to clean the wash
cabinet.
Then reprocess the load items again.
Wash pressure exceeds tol-
erance
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.
