Miele G 7804, Operating Instructions Manual

Page: 15 / 76

In order to achieve good cleaning
results, the machine needs to operate
with soft water. Hard water results in the
build-up of calcium deposits on the
load and inside the wash cabinet.
Mains water with a hardness level
higher than 0.7 mmol/l (4° dH – German
scale) needs to be softened. This takes
place automatically in the integrated
water softener.
– The water softener requires
reactivation salt.
– The machine 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 °dH German scale), always
programme the washer-disinfector to
the higher value (17 °dH or 3.1 mmol/l
in this example).
The built-in water softener has
settings from 1 °dH - 60 °dH (0.2 -
10.8 mmol/l).
For future servicing it is useful to make
a note of your water hardness level.
