Before using for the first time
24
Before using the appliance for
the first time, you require:
– approx. 1 kg dishwasher salt,
– domestic dishwasher detergent,
– rinse aid formulated for domestic
dishwashers.
Every dishwasher is tested at the fac‐
tory. There will be residual water in the
appliance from this test. It is not an in‐
dication that it has been used previ‐
ously.
Dishwasher salt
In order to achieve good cleaning re‐
sults, the dishwasher needs to operate
with soft water. Hard water results in a
build-up of calcium deposits on crock‐
ery and in the dishwasher.
Mains water with a hardness level high‐
er 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 in
the dishwasher is suitable for a water
hardness level of up to 12.6 mmol/l
(70 °d - German scale).
The water softener requires dishwasher
salt.
Depending on the water hardness level
(< 3.8 mmol/l, or 21 °d - German scale),
dishwasher salt is not required if combi‐
nation tablets are being used (see "Op‐
eration - Detergent").
If the water hardness in your area is
constantly lower than 0.9 mmol/l
(5 °d) , you do not need to add dish‐
washer salt. The prompt to add dish‐
washer salt will be switched off auto‐
matically. The water softener must,
however, still be programmed to cor‐
respond to the water hardness level in
your area.

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,
as other salts (e.g. cooking salt, agri‐
cultural grade or gritting salt) may
contain insoluble additives which
can impair the functioning of the wa‐
ter softener.
