Filling the container for dishwasher salt

Water hardness

In order to achieve excellent cleaning
results, the machine requires a supply of
soft water with a low calcium content. Hard
mains water results in the build-up of
calcium deposits on the load items and on
the wash cabinet walls.
Mains water with a water hardness of
0.7 mmol/l (4 °dH) or more must be
softened. This occurs automatically during a
programme sequence in the built-in water
softener.
The water softener must be set to the exact
hardness of the mains water (see "Setting
the water hardness").
Your local water authority can give you
information about the exact water hardness
in your area.
In the event of a fault, it will help the
service technician if you know the
hardness of your local water supply.
Record the hardness of the mains water
here:
______________________mmol/l or °dH
The water softener must be reactivated at
regular intervals. Special dishwasher salt is
required for this. Reactivation is carried out
automatically during a programme
sequence.
If the hardness level of your water is
consistently less than 0.7 mmol/l (=
4 °dH), salt is not required for the water
softener. However, the water hardness
level must still be set.

fluctuates between, for instance, 1.4 and
3.1 mmol/l (8 and 17 °dH), the water
hardness must be set to 3.1 mmol/l
(17 °dH).
