E 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.
E If the filter is activated, the program step Water Hardness no
longer appears.
E The IMPRESSA has 5 hardness degrees which can be used and
are displayed while you are adjusting the water hardness
