8.6 Scheduled maintenance
If enabled, this function displays a message to alert the user
when it is necessary to perform scheduled maintenance.
The first request for assistance appears when the number of
coffee, tea, heating unit filling cycles, or the number of days
elapsed since installation of the machine, is close to the pro-
grammed threshold value.
After reaching the programmed threshold value, the display
shows a window with messages:
Press the
icon to read the message:
This message continues to be displayed until maintenance is
performed.
If enabled, the display may show various scheduled mainte-
nance thresholds.
The threshold reached/exceeded warnings do not prevent the
machine from operating.
The messages on the display can be reset at any time (also
before the warning is triggered) and can be performed by the
technician.
When the machine is in operation, the system increases both
the cycle counter and time since installation counter.
Contact the Technician to programme this func-
tion.

Keep the heating unit pressure between 0.08 and 0.14 MPa (0.8 and 1.4 bar).

cated on the gauge, which must be between 0.8 and 0.9 MPa (8 and 9 bar).
Check the condition of the filters. Check for any damage on the edge of the filters
FILTERS AND FILTER
and check whether any coffee grounds settle in the coffee cup, and replace the
HOLDERS
filters and/or filter holders, as required.
Check the ground coffee dose (between 6 and 7 grams per time) and check the
degree of grinding. Grinders must always have sharp cutting edges. Too much pow-
der in the grounds is an indication that the coffee is deteriorating. We recommend
GRINDER-DISPENSER
contacting a Technician to replace the flat burrs after every 400/500 kg of coffee,
or after every 800/900 kg for conical burrs.
If the automatic grinder wear warning is enabled, follow the instructions in para.
8.7 on page 59.
Replace the water filter cartridge or regenerate the water softener at the frequency
WATER FILTER
indicated by the manufacturer or whenever the automatic regeneration warning is

months to replace the water in the heating unit.
