Water hardness
In order to achieve excellent cleaning re-
sults, the machine requires a supply of soft
water with a low calcium content. Hard tap
water results in the build-up of calcium de-
posits on wash items and on the wash cabi-
net walls.
Tap water with a water hardness of 4gpg
(4°dH) or more must be softened. This oc-
curs automatically during a program se-
quence in the built-in water softener.
The water softener must be set to the exact
hardness of the tap water (see “Setting the
water hardness”).
Your local water authority can give you in-
formation about the water hardness level in
your area.
It is useful to know your water hardness so
that you can provide the service technician
with this information in the event of any
subsequent service calls. Record the hard-
ness of the tap water here:
______________________gpg or °dH
The water softener must be reactivated at
regular intervals. Special reactivation salt is
required for this. Reactivation is carried out
automatically during a program sequence.
If the water hardness level of your water is
consistently less than 4gpg (= 4°dH), salt
is not required for the water softener. The
water hardness level must, however, still
be set.
Setting the water hardness
Water hardness can be set between 0 and
70gpg (0–70°dH).
The water hardness is preset to 14gpg
(14°dH) at the factory.
With varying water hardness, always set the
highest level. If the water hardness fluctu-
ates between, for instance, 8.3 and
17.7gpg (8 and 17°dH), the water hardness
must be set to 17.7gpg (17°dH).
Water hardness setting values can be found
in the chart on the next page.
