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 in
this dishwasher is suitable for a water
hardness level of up to 12.6 mmol/l
(70 °d - German scale).
– The water softener requires
dishwasher salt.
Depending on the water hardness
level (
ß
3.8 mmol/l, or 21 °d German
scale), 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.
Where the water hardness fluctuates,
e.g. between 6.7 - 9.0 mmol/l (27 -
30 °d - German scale), always
programme the dishwasher to the
higher value (9.0 mmol/l in this
example).
The dishwasher is programmed at
the factory for a water hardness level
of 2.7 mmol/l (15 °d - German scale).
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.
