4. Adjusting the water hardness
Water is heated in the IMPRESSA F50/F5. As a result, cal-
cification occurs during normal use and is indicated auto-
matically. Before using the IMPRESSA F50/F5 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 F50/F5 has 5 hardness degrees which can
be used and are displayed while you are adjusting the water
hardness.
The displayed information means the following:
LEVEL –– Water hardness function switched off
LEVEL 1
German water hardness degree 1 to 7°
French Water hardness degree 1.79 – 12.53°
LEVEL 2
German water hardness degree 8 to 15°
French Water hardness degree 14.32 – 26.85°
LEVEL 3

French Water hardness degree 28.64 – 41.14°
LEVEL 4
