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 wash cabinet walls.
Mains water with a water hardness level
higher than 0.9 mmol/l (5 °dH – 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
12.6 mmol/l (70 °dH – German scale).
In order to maintain the functions of
the water softener, it must be reactiv-
ated regularly. Reactivation occurs
automatically every ninth programme
sequence. At the start of the next pro-
gramme, an additional 4.4 l of water is
required for this process. Energy con-
sumption increases by 0.015 kWh and
the programme is extended by approx.
3 minutes.
The above only applies to the ECO
programme at a water hardness of
2.5 mmol/l (14 °dH – German scale).
For other programmes and water
hardness levels, the frequency of re-
activation will differ.
In order to be reactivated, the water
softener requires dishwasher salt.
Depending on the water hardness level
(< 3.8 mmol/l, or < 21 °dH – German
scale), dishwasher salt is not required if
combination detergents are being used
(see “Detergent – Powder detergent and
detergent tabs”).
If the water in your area is very soft
and constantly
lower than 0.9 mmol/l
(5 °dH – German scale) , you do not
need to add dishwasher salt. The salt
refill indicator will automatically switch
off after the water hardness has been
set accordingly (see “Settings – Water
hardness”).

Damage to the water softener
from detergent.
Detergent will damage the water
softener.
Do not fill the salt reservoir with
powder or liquid detergent.

Damage caused by using unsuit-
able salts.
Some types of salt may contain in-
soluble components which can
cause the water softener to malfunc-
tion.
Only use special coarse-grained
dishwasher salt or other pure kitchen
salt for reactivation.
If you only ever use combination de-
tergent products in your dishwasher,
you can turn off both refill reminders if
you wish (see “Settings – Refill re-
minders”).
Please make sure that if you stop us-
ing combination detergent products,
you refill the dishwasher salt and
rinse aid. Switch the refill reminders
back on if required.
