– Adjust the rinse aid dosage
Set 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 det-
rimental 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, German de-
grees (°dH), 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.
