Water softener
To avoid scale deposits on the dishes and in the dishwasher, the dishes
must be washed with soft water, i.e. water with a low lime content. The
dishwasher therefore has a built-in water softener, in which tap water
with a hardness of 4°d (German degree) and harder is softened with the
aid of special salt.
3 Your water supplier will be able to inform you about the hardness and
hardness range of the water in your area.
The water softener can be set manually using the water hardness
switch; it can also be set electronically using the buttons on the control
panel.
