If you are using the CLEARYL Blue filter cartridge and have
activated it in programming mode, you will not be able to
adjust the water hardness.
The harder the water is, the more frequently the IMPRESSA needs to
be descaled. It is therefore important to adjust the water hardness.
The water hardness can be adjusted on a continuous scale between
1° dH and 30° dH. It can also be deactivated, which means that the
IMPRESSA will not let you know when it has to be descaled.
