Problem
Cause and remedy
Stainless steel items are
showing signs of corro-
sion.
The stainless steel is of insufficient quality for machine
reprocessing.
Only use stainless steel items made of high quality
stainless steel and follow the instructions of the
manufacturer regarding machine reprocessing.
The chloride content in the water is too high.
Have a water analysis check carried out. Connection to
an external water processing unit and the use of
demineralised water may be necessary.
Neutralisation has not taken place during the programme.
Check the level in the supply container and vent the
dispensing system if necessary.
Rust or superficial rust has built up in the wash cabinet,
e.g. due to an excessively high iron content in the water or
rust on other wash load items.
Check the installation.
Discard any rusty items.

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

The set spin speed has not been reached.
– Load items are obstructing the machine or basket spray
arms.
Arrange the load items so that the spray arms can turn

– The relevant spray arm is blocked.
Clean the spray arm.
Check whether the filters in the wash cabinet are clean
and correctly inserted.
Start the programme again.
– Wash pressure is too low due to a heavy build-up of
foam.
Follow the instructions regarding foam build-up in
“Chemical processes and technology”.
Start the
