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 °dH – 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 °dH 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 °dH -35 °dH (0.2 -
6.3 mmol/l).
If the water hardness level exceeds
35 °dH or 6.3 mmol/l then a water
softening system, e.g. the Miele
"Aqua-Soft system G 7897", should be
considered.
In the event of a fault, it will help the
service technician if you know the
hardness of your local water supply.
