4.2 Water hardness
According to the water hardness in
your region, or if you have not
inserted a filter (see chapter 4.1),
sooner or later the machine needs
descaling. So that the system can
indicate accurately when desca-
ling is necessary, you must enter
the correct water hardness set-
tings before first use.
The default setting is level 3.
First, test your water with the test
strips provided:
➔ Dip the strip into the water and
then shake it lightly off.
➔ After about a minute you can
read the result by counting the red
dots on the test strip.
➔ The settings corresponding to
the different levels of hardness are
as follows:
Note: If none of the dots turn red
on the test strip, please set to
level 1.
➔ Switch your machine to Stand-
by mode.
➔ Press the steam warm-up button
(fig. 1/M) for about 4 seconds.
➔ The water hardness is indicated
by the number of buttons lit up as
detailed below.
➔ Press the steam warm-up button
repeatedly until the buttons which
indicate your level of water hard-
ness light up.
➔ Press the Stand-by button to
confirm.
➔ To confirm your settings, the
buttons which indicate the level
selected flash twice consecutively.
➔ The programming operation is
then complete and the system is
restored to coffee-brewing mode.
Note: If you interrupt your pro-
gramming operation for more than

automatically back into coffee-
brewing mode.
