Using for the first time
Measuring water hardness
You can measure the water hardness
yourself using the enclosed test strip.
Alternatively, your local water authority
will be able to tell you the hardness of
water in your area.
^ Dip the strip in your drinking water for
approximately one second, then
shake off any excess water. The
result will be evident after about a
minute.
Now you can set the water hardness for
your coffee machine.
Setting the water hardness level
^ Touch "Settings" %.
^ Swipe across the screen until "Water
hardness" appears, then touch it to
select it.
^ Touch the required water hardness
level and confirm with OK.
The setting is now saved.
