Water softener
To avoid scale deposits on the dishes and in the dish-
washer, 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.
Your water supplier will be able to inform you
3
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.
