Problem
Possible cause and solution
Stainless steel items are
showing signs of corro-
sion.
The stainless steel is of insufficient quality for machine re-
processing.
Only use stainless steel items made of high quality stain-
less 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 dem-
ineralized water may be necessary.
Neutralization has not taken place during the program.
Check the level in the supply container and vent the dis-
pensing 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.
