9.2.2.1 PLUS Model maintenance warning
system, consumption resetting
The word Servizio on the display
means that the value set in TE-
CHNICAL LEVEL programming of

To reset this signal simply feed the
machine by keeping A and B pres-
sed contemporaneously.
The display will now indicate the
reset operations.

9.2.1.3. Setting litres to zero, filter replacement

When the display shows (Fig.I°) it means that the
value set in TECHNICAL PROGRAMMING of the
litres that can be purified by the filter has been
exceeded.
To set this signalling to zero just supply the machine
by keeping buttons C and D pressed at the same
time (group 1)
Now the display will show the Reset operations (Fig.

Wait for dosing to go back to idle-on.
Then the display will go back to the initial setting
(Fig.III°).
This procedure will set the litre reading to zero and
"eliminate" the "Change H2O Filter" indication.
