Water Softener - Miele G 663 Plus Operating Instructions Manual

Before using for the first time

Water softener

To achieve good cleaning results, the
dishwasher needs soft water. Hard
water results in calcium deposits on
dishware and in the dishwasher.
If your tap water hardness is above
8 gr/gal (140 ppm), the water should be
softened. This takes place
automatically in the unit's integrated
water softener.
– Your local water authority will be able
to advise you of the water hardness
level in your area.
– The water softener must be filled with
dishwasher salt for reactivation.
If your water hardness is lower than
8 gr/gal (140 ppm), you do not need
to add dishwasher salt.
If there is a fault, it will help the service
technician to know the hardness of your
local water supply.
