4. Adjusting the water hardness

Water is heated in the IMPRESSA. As a result, calcification oc-
curs during normal use and is indicated auto matically. Before
using the IMPRESSA for the first time the hardness of the water
used must be adjusted. Use the supplied test sticks for this.
1° German hardness is equivalent to 1.79° French hardness.
If the filter is activated, the program step Water Hardness no
longer appears.
The IMPRESSA has 5 hardness degrees which can be used and
are displayed while you are adjusting the water hardness.
The displayed information means the following:
