5.5 Water hardness
The built-in water softener removes limescale from the water, enabling prob-
lem-free cleaning. Automatic regeneration occurs at regular intervals, thus
guaranteeing its effectiveness.
Your appliance is equipped with an automatic limescale sensor. Configuring
the level of water hardness is therefore not necessary. The appliance automat-
ically starts the regeneration process at the right time.
After regeneration, the next programme starts by rinsing out the water softener
by pumping water through it and draining simultaneously.
For hygiene reasons, regeneration salt is also recommended for use with low
water hardness and detergents.
For information on the level of water hardness in your area, contact
your local water authority.
The unit of water hardness can be set to the
French degree of water hardness (°fH) or the
German degree of water hardness (°dH).
Setting the water hardness unit (see page 20)
The water hardness setting can be changed to
suit local conditions.
Setting the water hardness (see page 20)
The water softener is deactivated at level 0‑5 °fH or 0‑3 °dH.
