Water Softener; Programming The Water Softener - Miele G 7881 Operating Instructions Manual

In order to achieve good cleaning
results, the washer-disinfector needs to
operate with soft water. Hard water
results in the build-up of calcium
deposits on instruments etc. and in the
washer-disinfector.
Mains water with a hardness level
higher than 0.7 mmol/l (4° d – German
scale) needs to be softened. This takes
place automatically in the integrated

water softener.

– The water softener requires
reactivation salt.
– The washer-disinfector must be
programmed to correspond to the
water hardness in your area.
– Your local water authority will be able
to advise you on the water hardness
in your area.
Where the water hardness fluctuates
e.g. between 1.4 - 3.1 mmol/l (8 - 17 °d
German scale) always programme the
washer-disinfector to the higher value
(3.1 mmol/l in this example).
The built-in water softener has
settings from 1 °d - 60 °d (0.2 -
10.8 mmol/l).
In the event of a fault, it will help the
service technician if you know the
hardness of your local water supply.
Enter the water hardness below:
°d / mmol/l
