Water softener
In order to achieve good cleaning res-
ults, 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
higher 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 dish-
washer salt.
Depending on the water hardness
level (< 3.8 mmol/l, or 21 °d - German
scale), dishwasher salt is not required
if combination tablets are being used
(see "Operation, Detergent").
– The dishwasher must be pro-
grammed to the correct water hard-
ness for your area.
– Your local water authority will be able
to advise you of the water hardness
level in your area.
– Where the water hardness fluctuates
e.g. between 1.8 and 2.7 mmol/l (10 -
15 °d - German scale) always pro-
gramme the dishwasher to the higher
value (2.7 mmol/l or 15 °d in this ex-
ample).
In the event of a fault, it will help the
service technician if you know the hard-
ness of your local water supply.
Enter the water hardness below:
____________mmol/l or °d
The dishwasher is programmed at the
factory for a water hardness level of 2.7
mmol/l (15 °d - German scale).
If this setting corresponds to the hard-
ness of your water you do not need to
do anything more.
However, if you have a different water
hardness you must adjust the water
softener to match your water hardness.
