4. Adjusting the water hardness

Water is heated in the IMPRESSA. As a result, calcification occurs during normal use and is indicated automatically. 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:

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 4 German water hardness degree 24 to 30° French Water hardness degree 42.96 – 53.7°
