3.7 Adjusting for water hardness

The water is heated inside the machine. With use, this leads to
calcium deposits (furring) forming on the machine. This is automa-
tically indicated in the display. For this reason, it is necessary to
adjust the machine to the hardness of your local water before you
use it for the first time. Use the enclosed test-sticks for this purpose.
1° water hardness on the German scale represents 1.79° on
the French scale.
The machine has got 5 hardness settings to choose from. The
chosen grade is shown on the display
