4.2 Water hardness

Depending on the water hardness in your region, the appliance will have to be
descaled sooner or later. In order for the system to be able to indicate in good time
when descaling is necessary, you must enter the correct water hardness before using
the coffee machine for the first time.
You should first test the water with the enclosed test strips:
• Briefly dip the strips into the water and shake off excess water.
• You can read off the result after approx. one minute by counting the red dots
• The different levels are divided as follows:
– 1 red dot
– 2 red dots =
– 3 red dots = 15–21° dH / 25.3–37.8° fH = Level 3
– 4 red dots =
☛ If no dots are red, set Level 1.
The basic factory setting is Level 3.
