Water softener
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 dish‐
ware and in the dishwasher.
Water supplies with a hardness level
higher than 4 gr/gal (4 °d) needs to be
softened. This takes place automatical‐
ly in the integrated water softener. The
water softener in the dishwasher is suit‐
able for a water hardness level of up to
73 gr/gal (70 °d).
– The water softener requires dish‐
washer salt.
Depending on the water hardness
level (< 22 gr/gal, or 21 °d), dish‐
washer salt is not required if combi‐
nation tablets are being used (see
"Operation - Detergent").
– The dishwasher must be program‐
med for the water hardness in your
area.
– Your local water supplier can tell you
the water hardness level in your area.
– Where the water hardness fluctuates
e.g. between 10 - 16 gr/gal (10 - 15
°d), always program the dishwasher
to the higher value (16 gr/gal or 15 °d
in this example).
It is useful to know your water hardness
so that you can provide the service
technician with this information in the
event of any service calls.
Enter the water hardness below:
____________ gr/gal (°d)
The dishwasher is programmed at the
factory for a water hardness level of 1
gr/gal (1 °d).
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.
