Water softener
In order to achieve good cleaning
results, the dishwasher needs to
operate with soft water. Hard water
results in the build-up of calcium
deposits on crockery 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
softener unit. The softener unit is
suitable for a water hardness level of up
to 12.6 mmol/l (70 °d).
– The water softener requires
reactivation salt.
Depending on the water hardness
level (
ß
21 °d), dishwasher salt is not
required if combination tablets are
being used (see "Detergent").
– The dishwasher must be
programmed for 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 event of a fault, it will help the
service technician if you know the
hardness of your local water supply.

Enter the water hardness:
mmol/l or °d
The dishwasher is set at the factory
for a hardness level of 0.2 mmol/l
(1 °d).
If this setting corresponds to the
hardness of your water, you do not
need to do anything more.
If your water is harder, you will need to
programme the water hardness level.
