GAUGE
Keep the boiler pressure between 0,08 and 0,14 MPa (0,8 and 1,4 bar).
X
GAUGE
Periodically check the water pressure when coffee is being dispensed: check
the pressure indicated on the gauge, which must be in the range of
0,8 and
0,9 MPa (8 and 9 bar)
.
X
FILTERS AND FILTER
HOLDERS
Check the condition of the filters. Check for any damage on the edge of
the filters and check whether any coffee grounds settle in the coffee cup
and replace the filters and/or filter holders, as required.
X
GRINDER-DISPENSER
Check the ground coffee dose (between 6 and 7 grams per time); check
the degree of grinding. The grinders must always have sharp cutting
edges. Their deterioration is indicated by the presence of too much pow-
der in the grounds. We recommend calling the Maintenance Technician
to replace the flat grinders after every 400/500 kg of coffee. For conical
grinders, replace every 800/900 kg.
X
WATER SOFTENER
FILTER
Replace the water filter cartridge or replenish the water softener as often
as specified by the manufacturer.
If the "Filter completely worn" warning appears on the display, contact the
Technical Assistance in order to replace the filter and reset the warning.
X
GAS SYSTEM
Check for any gas leaks in the system by passing a soapy solution through
the pipes.
X
BOILER
Request the intervention of the Maintenance Technician at least every
three months to carry out the replacement of the water in the boiler.
X
Problems to the components highlighted in grey require shutting
down the machine and the intervention of the Maintenance
Technician.
8.3
Maintenance after a short period of
machine inactivity
"Short period of inactivity" refers to a period of time
exceeding one working week.
If the machine is reactivated after this period, the
Maintenance Technician must replace all the water con-
tained in the hydraulic circuits as indicated in para. "8.2
Periodic Maintenance" on page 75.
Furthermore, all periodic maintenance operations
must be carried out, see the previous paragraph.
