Cause and remedy
The rinsing agent dosage is set too low.
Increase the dosage (see "Further settings, Additional

functions, Dispensing system").
There is no salt in the salt reservoir.
Fill the salt reservoir (see "Filling the salt reservoir").

The water softener is programmed to too low a water hard-
ness level.
Programme the water softener to the correct value (see

"Further settings, Water hardness").
This may be caused by the ingredients of the cleaning
agent.
Switch to another cleaning agent.

The glassware is not dishwasher-proof. The surfaces are
affected.
Purchase glassware which is dishwasher-proof.

The wash temperature of the selected programme was too
low.
Select a programme with a higher main wash

temperature.
The bleaching effect of the cleaning agent used is too low.
Switch to another cleaning agent.

Natural dyes e.g. from carrots or tomatoes may be the
cause. The amount of detergent used or its bleaching ef-
fect was not sufficient to deal with natural dyes.
Use more detergent (see "Operation, Detergent").

Discoloured plastic items will not regain their original col-
our.
The affected items are not corrosion-resistant.
Purchase cutlery that is dishwasher-safe.

The "Cold" programme was not run after dishwasher salt
was added. Traces of salt have got into the normal wash
cycle.
Always run the "Cold" programme without any load

items after refilling the salt.
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 load items.
Discard any rusty load items.
