Using for the first time
Water softener
In order to achieve good cleaning
results, the dishwasher needs to
operate with soft (low limescale) water.
Hard water results in the build-up of
calcium deposits on crockery and in the
appliance.
Water with a hardness level higher than
0.9 mmol/l (5 °dH – German scale) must
be softened. This occurs automatically
in the integrated water softener. The
water softener is suitable for a water
hardness level of up to 12.5 mmol/l
(70 °dH - German scale).
In order to be reactivated, the water
softener requires dishwasher salt.
Depending on the water hardness level
(< 3.8 mmol/l, or < 21 °dH – German
scale), dishwasher salt is not required if
combination detergents are being used
(see "Detergents - Types of
detergents").
- The dishwasher needs to be
programmed to the correct water
hardness for 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 1.8 and 2.7 mmol/l (10 -
15 °dH - German scale), always
programme the dishwasher to the
higher value (2.7 mmol/l or 15 °dH in
this example).

If the water hardness in your area is
available in a unit other than °dH, you
can convert the values as follows:
1 °dH = 0.18 mmol/l = 1.78°fH
The dishwasher is programmed at the
factory for a water hardness level of
2.5 mmol/l (14 °dH - German scale).
If your water hardness level
corresponds to this setting, you can
skip to the next section.
However, if you have a different water
hardness level, you must adjust the
water softener to match your water
hardness.
