FILLING BOILER
MANUALLY
All models are equipped with a
level gauge to keep the water level inside the
boiler constant.
When using the machine for the first time, it is
advisable to fill the boiler by hand to avoid
damaging the electrical resistor and turning on
the electronic protection.
If this should happen, just turn the machine off
and then start it up again to complete its loa-
ding procedure (see chapter "MACHINE
FUNCTIONS MESSAGE – LEVEL ERROR").
To fill the boiler manually for the first time, pro-
ceed as follows:
• remove the worktop grid;

• turn the manual "A" level tap so that water
will enter the boiler;
• once the maximum level has been reached,
as indicated by the optical level, turn tap "A"
off;

• switch the machine on by placing the gene
ral switch on "I"; this will activate the level
gauge which will automatically maintain the
water level inside the boiler.
