The water softener
The dishwasher is equipped with a water softener designed to
remove minerals and salts from the water supply, which would
have a detrimental or adverse effect on the operation of the
appliance.
The higher the content of these minerals and salts, the harder
your water is.
Water hardness is measured in equivalent scales, Clarke degrees,
French degrees (°TH) and mmol/l (millimol per litre -
international unit for the hardness of water).
The softener should be adjusted according to the hardness of the
water in your area.Your local Water Authority can advise you on
the hardness of the water in your area.
The water softener must be set in both ways: manually, using the
water hardness dial and electronically, using the function buttons
on the control panel.
a) Setting manually
1. Open the dishwasher door.
2. Remove the lower basket from the dishwasher.
3. Turn the water hardness dial to position 1 or 2 (see table).
