Water softener
In order to achieve good cleaning re‐
sults, the dishwasher needs t
o 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 dish‐
washer salt.
Dependin
g on the water hardness
level (< 3.8 mmol/l, or 21 °d - Ger‐
man scale), dishwasher salt is not re‐
quired if combination tablets are be‐
ing used (see "Operation, Deter‐
gent").
The dishwasher must be program‐
med t
o the correct water hardness
for your area.
Your local water authority will be able
t
o 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 pr
o‐
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
ser
vice 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
fact
ory 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
har
dness you must adjust the water
softener to match your water hardness.
