Water Softener - Miele G 658 Plus Operating Instructions Manual

To achieve good cleaning results, the
dishwasher needs soft water. Hard wa-
ter results in calcium deposits on
dishware and in the dishwasher.
If your tap water hardness is above
8 gr/gal (values are in US gallons)
(140 ppm), the water should be soft-
ened. 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 dishwasher must be pro-
grammed to correspond to the water
hardness in your area.
– The water softener must be filled with
dishwasher salt for reactivation.

If your water hardness is consistently
lower than 8 gr/gal (140 ppm), you do
not need to add dishwasher salt. How-
ever, the dishwasher must still be pro-
grammed to correspond to the local
water hardness.
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
local water supply.
