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
water softener.
– The water softener requires
dishwasher salt.
– 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 6.7 - 9.0 mmol/l (37 -
50 °d German scale) always
programme the dishwasher to the
higher value (9.0 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 below:
mmol/l or °d
The dishwasher is set at the factory
for a hardness level of
2.2 - 2.7 mmol/l (12 - 15 °d ).
If this setting corresponds to the
hardness of your water you do not need
to do anything more.
If your water is harder or softer, you will
need to programme the water hardness
level. See following section.
