Water softener
In order to achieve good cleaning
results, the dishwasher needs to
operate with soft water. Hard water
results in a build-up of calcium deposits
on dishware and in the dishwasher.
Domestic 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
12.6 mmol/l (70 °dH – German scale).
In order to be reactivated, the water
softener requires reactivation salt.
Depending on the water hardness level
(< 3.8 mmol/l, or < 21 °dH – German
scale), reactivation salt may not be
required if combination detergents are
being used (see “Active ingredients”
under “Detergents”).
- You should program the dishwasher
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 or
10–15 °dH – German scale), always
program the dishwasher to the higher
value (2.7 mmol/l or 15 °dH – German
scale 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 1 °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.
