Water softener

Water hardness
In order to achieve good cleaning results, the machine needs to
operate with soft water. Hard water results in the build-up of calcium
deposits on the load and in the machine.
Mains water with a water hardness of 0.7mmol/l (4°dH) must be
softened. This occurs automatically in the built-in water softener.
The water softener must be set to the exact hardness of the mains
water (see “Water softener/Setting the water hardness”).
Your local water authority will be able to tell you the exact degree of
hardness in the mains water supply.
For future servicing it is useful to make a note of your water
hardness level. Enter your water hardness level here:
________________________mmol/l or °dH
The water softener must be reactivated at regular intervals. This
requires special reactivation salt (see “Water softener/Filling the salt
reservoir”). Reactivation is carried out automatically during a
programme sequence.
If the hardness level of your water is constantly less than 0.7mmol/
l (= 4°dH), salt is not required for the water softener. The water
hardness level must, however, still be set.
