Problem
Cause and remedy
Spray arm monitoring - upper
spray arm: Spray arm blocked
or excessive foaming
or
Spray arm monitoring - lower
spray arm: Spray arm blocked
or excessive foaming
or
Spray arm monitoring - mobile
unit spray arm 1 - : spray arm
blocked or excessive foaming
The rotation speed set has not been reached.
- Items are obstructing the machine or basket spray arms.

Follow the instructions regarding foam build-up in
“Chemical processes and technology”.
Start the
Rinsing
programme in order to clean the wash
cabinet.
Then reprocess the load again.
Spray pressure exceeds tol-
erance
The wash pressure differs from the reference value.
Possible causes of fluctuations in the wash pressure in-
clude:
- Defective water connections,
- Open adapters,
- Foam build-up.
Identify and resolve the cause of this.
The programme is not interrupted. Nevertheless, you
must reprocess the load.
Excessive spray pressure

A programme was interrupted because of severe fluctu-
ations in the wash pressure.
Possible causes of fluctuations in the wash pressure in-
