MAINTENANCE AND CLEANING
Safety precautions
9.1
Carefully read the instructions provided in chapter "2. SAFETY
PRECAUTIONS" on page 50 .
Periodic Maintenance
9.2
Besides carrying out maintenance activities according
to the frequency specified in the table, a general inspec-
tion must be carried out on the machine at least once a
year by a Qualified Technician.
Component Type of intervention
GAUGE Keep the boiler pressure between 0.8 and 1.4 bar.
Periodically check the water pressure when coffee is being dispensed: check
GAUGE
the pressure indicated on the gauge, which must be in the range of 8 to 9 bar.
Check the condition of the filters. Check for any damage on the edge of
FILTERS AND FILTER HOLD-
the filters and check whether any coffee grounds settle in the coffee cup
ERS
and replace the 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. The grinders must always have sharp cut-
ting edges. Their deterioration is indicated by the presence of too much
GRINDER-DISPENSER
powder in the grounds. We recommend calling the Qualified Technician
to replace the flat grinders after every 400/500 kg of coffee. For conical
grinders, replace them after every 800/900 kg.
Replace the water filter cartridge or replenish the water softener as often
WATER SOFTENER as specified by the manufacturer.
FILTER If the "Filter completely worn" warning appears on the display, contact the
Technical Assistance in order to replace the filter and reset the warning.
Check for any gas leaks in the system by passing a soapy solution through
GAS SYSTEM
the pipes.
We recommend that you call out the Technical Assistance at least once
BOILER
every three months to replace the water in the boiler.
Component problems highlighted in grey require the machine to
be switched off and one of the Qualified Technicians to be called
out.

If the machine is switched back on after this period,
a Qualified Technician must replace all the water inside
the hydraulic circuits as indicated in para. "9.2 Periodic
Maintenance" on page 82.
Furthermore, all periodic maintenance operations
