The 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 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 de-
grees 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, us-
ing the water hardness dial and electronically, using the
function buttons on the control panel.
