Water hardness
In order to achieve good cleaning results, the dishwasher needs to
operat
e with soft (low in calcium deposits) water. Hard water results
in a build-up of calcium deposits on cookware and in the dishwasher.
Water with a hardness level higher than 4 °dH 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 70 °dH (12.6 mmol/l).
The water softener in the dishwasher has to be set to the hardness
level
of your water supply.
Your local water supplier can tell you the water hardness level in
yo
ur area.
Where the water hardness fluctuates (e.g. 16-28 gpg / 15-27°d),
a
lways program the dishwasher to the higher value (in this example,
28 gpg / 27°d).
If the hardness of your water constantly lies under 4 gpg (4 °dH), no
salt
must be filled in the water softener.
It is useful to know your water hardness so that you can provide the
ser
vice
technician with this information in the event of any service
calls.
