23
Before using the machine for

ers,
– rinse aid for commercial dishwash-
ers.

Miele Professional.
Every dishwasher is tested at the fact-
ory. There will be residual water in the
machine from this test. It is not an in-
dication that the dishwasher has been
used previously.
Dishwasher salt
In order to achieve good cleaning res-
ults, the dishwasher needs to operate
with soft water. Hard water results in
the build-up of calcium deposits on
crockery and on the inner surfaces of
the machine.
Mains water with a hardness level
higher than 0.7 mmol/l (4 °d - German
scale) must be softened. This occurs
automatically in the integrated water
softener. The water softener is suitable
for a water hardness level of up to
6.5 mmol/l (36 °d - German scale).
The water softener requires reactivation
salt.
If the water in your area is very soft
and constantly
lower than 0.9 mmol/l
(5 °d - German scale) you do not
need to add dishwasher salt. The wa-
ter softener is automatically reactiv-
ated.

Dishwasher detergent will dam-
age the water softener.
Do not fill the salt reservoir with
powder or liquid detergent.

Only use special coarse grained
dishwasher salt for reactivation.
Other salts may contain insoluble ad-
ditives which can impair the func-
tioning of the water softener.
