Miele G 891 - Water Hardness Settings and Table

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 dishware 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 your water hardness is consistently
lower than 84 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 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
local water supply.
