Water Softener - Miele G 681 Operating Instructions Manual

Water softener

To achieve good cleaning results, the
dishwasher needs soft water. Hard wa-
ter results in the build up of calcium de-
posits on tableware and in the dish-
washer. If your tap water hardness is
above 8 gr/gal (140 ppm), the water
should be softened. This takes place
automatically in the integrated water
softener.
– The water softener must be filled with
dishwasher salt for reactivation.
– The dishwasher must be pro-
grammed to correspond to the water
hardness in your area.
– Your local water authority will be able
to advise you of the water hardness
level in your area.
If the hardness of your tap water is con-
stantly lower than 8 gr/gal (140 ppm),
do not add dishwasher salt. However,
the dishwasher must still be pro-
grammed to correspond to the water
hardness level in your area.
Where the water hardness fluctuates
e.g. between 9 - 17 gr/gal
(160 - 310 ppm), always program the
machine to the higher value (17 gr/gal,
310 ppm in this example).
If there is a fault, it will help the service
technician to know the hardness of your
tap water.
