Water softener
In order to achieve good cleaning re-
sults, the dishwasher needs to operate
with soft water. Hard water results in
the build-up of calcium deposits on
crockery and in the dishwasher. Hence
if mains water hardness is above 4 °d
(0.7 mmol/l), the water should be soft-
ened. This takes place automatically in
the integrated water softener.
– The water softener must be filled
with dishwasher salt for reactivation.
– The dishwasher must be pro-
grammed to correspond to the water
hardness in your area.
– Your local water authority will advise
you on the highest level of water
hardness in your area.
If the hardness of your local supply is
constantly lower than 4 °d (0.7 mmol/l),
you do not need to add dishwasher
salt. The dishwasher must, however,
still be programmed to correspond to
the water hardness level in your area.
Where the water hardness fluctuates
e.g. between 8 - 17 °d (1.4 - 3.1 mmol/l),
always programme the machine to the
higher value (17 °d/3.1 mmol/l in this
example).
In the case of a fault, it will help the ser-
vice technician if you know the hard-
ness of your local water supply.
