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 appliance.
Mains water with a hardness level
higher than 0.9 mmol/l (5 °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
12.6 mmol/l (70 °d – German scale).
In order to maintain the water softener’s
functions, the water softener must be
reactivated regularly. Reactivation oc-
curs automatically every ninth pro-
gramme sequence. At the start of the
next programme, an additional 4.4 l of
water is required for this process. En-
ergy consumption increases by
0.015 kWh and the programme is ex-
tended by 3 minutes.
The above only applies to the ECO pro-
gramme at a water hardness of
2.5 mmol/l (14 °d – German scale). For
other programmes and water hardness
levels, the frequency of reactivation 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 °d – German
scale), dishwasher salt is not required if
combination detergents are being used
(see the “Detergent” chapter, “Active in-
gredients” section).
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 salt
refill indicator will automatically switch
off after the water hardness has been
set accordingly (see the “Settings”
chapter, “Water hardness” section).
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 kinds of salts may contain in-
soluble additives that can impair the
functioning of the water softener.
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 switch off both refill reminders
if you wish (see “Settings” chapter,
“Refill reminders” section).
Please make sure that if you stop us-
ing combination detergents, you refill
the dishwasher salt and rinse aid.
Switch the refill reminders back on if
required.
