Miele G 7836 CD, Operating Instructions Manual

Page: 15 / 64

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.
The water softener is set ex-works for a
hardness level of 3.4 mmol/l or 19°d.
If your water hardness differs from
this (even if it is below 0.7 mmol/l or
4°d) you will need to programme the
level into your machine.
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).
For future servicing it is useful to make
a note of your water hardness level.

°d or mmol/l
Setting the water softener
When the machine is first
commissioned the Miele service
technician has to set the machine for
your local water hardness level (see
Programme manual,
Operation/Reactivation).
Reactivation display
After a certain number of cycles the
message REACTIVATION will appear in
the display to warn you that the water
softener is depleted and cannot supply
any more softened water.
As soon as
the programme has finished
reactivation salt will need to be
replenished.
If this cannot be done immediately, and
further cleaning cycles have been
carried out, the reactivation process will
need to be carried out twice in
succession.
