In order to achieve good cleaning re-
sults, the dishwasher needs to operate
with soft water. Hard water results in the
build-up of calcium deposits on crock-
ery and in the dishwasher.
Mains water with a hardness level
higher than 0.7 mmol/l (4° d – German
scale) needs to be softened. This takes
place automatically in the integrated
water softener.
– The water softener must be filled with
dishwasher salt for reactivation.
– The dishwasher must be pro-
grammed to correspond to the water
hardness in your area.
– Your local water authority will be able
to advise you of the water hardness
level in your area.

Where the water hardness fluctuates
e.g. between 1.4 - 3.1 mmol/l (8 - 17 °d
German scale) always programme the
dishwasher to the higher value
(3.1 mmol/l in this example).
In the case of a fault, it will help the ser-
vice technician if you know the hard-
ness of your local water supply.
