2 Preparing and using your IMPRESSA for the first time
oThe water hardness can be adjusted between 1° dH and 30° dH. This can also be deactivated, which means that the IMPRESSA won’t let you know when it has to be descaled.
You can find out what the water hardness is by using the Aquadur® test strips enclosed in the Welcome Pack.
l Hold the test strip briefly (for one second) under flowing mains water. Shake off the water.
l Wait for about 1 minute.
l You 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:
