Filter rinsing stops automatically after approx. 500 ml. HEATING appears on the display, then READY is dis- played. The filter is now activated.

EHowever, if you are using the CLARIS filter cartridge and have activated it, you will not be able to adjust the water hard- ness.

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. This can also be deactivated, which means that the IMPRESSA will not let you know when it has to be descaled.

You can find out what the water hardness is by using the Aquadur® test strip supplied as standard.

THold the test strip briefly (for one second) under flowing water. Shake off the water.

TWait for about one minute.

TYou will then be able to read the degree of water hardness from the discolouration of the Aquadur® test strip and the description on the packaging.

You can now adjust the water hardness.

Example: To change the water hardness from 16°dH to 25°dH, proceed as follows:

Precondition: READY is displayed.

TOpen the cover of the Rotary Switch.

kT Keep the Rotary Switch pressed until RINSE appears.
