coffee, but we recommend replacing the filter within one week!
Attention: The filter should be changed every 2 months if you
use less than 50 liters of water. In this case, no message will
appear in the display.

ties, calcium will build-up inside the machine. Since the Water
Hardness Selector is off, the machine will not remind you when
to decalcify. This could clog and ruin your machine.
