Setting the water hardness

If the adjacent display lights up in the service mode, the water hardness can
be set.
Setting the water hardness regulates how frequently you are requested to
descale the appliance. The harder the water, the more frequently the appli-
ance has to be descaled.
Information
The water hardness cannot be set if you use a water filter (see section 7.6
Using a water filter on page 91). If a water filter is used, the water hardness
is set to soft.
Determine the water hardness with the enclosed test strip. Observe the
instructions on the test strip packaging and in the table Water hardness
range on page 97.
