Periodic Maintenance

7.3
Besides carrying out the following Maintenance ac-
tivities with the specified frequency, ask the Qualified
Technician to perform a general check of the machine
at least once a year.
Component Type of intervention
GAUGE Keep the boiler pressure between 0.8 and 1.4 bar.
Periodically check water pressure during coffee delivery: check the pres-
GAUGE
sure indicated on the gauge, which must be in the range 8 to 9 bar.
Check the condition of the filters. Check for any damage on the edge of
FILTERS and PORTAFILTERS the filters and check whether any coffee grounds settle in the coffee cup
and replace filters and/or filter holders, as required.
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
GRINDER-DOSER
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 every 800/900 kg.
WATER FILTER Replace the water filter or softener regeneration cartridge with the fre-
SOFTENER quency specified by the manufacturer.
Check for any gas leaks in the system passing a soapy solution on the
GAS SYSTEM
pipes.
Request the intervention of the Technical Assistance at least every three
BOILER
months to carry out the replacement of the water in the boiler.
Problems to the components highlighted in grey require shutting
down the machine and the intervention of the Qualified Technician.
Maintenance after a brief machine
7.4
inactivity
"Short machine downtime" refers to a period of time
exceeding one working week.
When reactivating the machine after this period, the
Qualified Technician must change completely the water
contained in the hydraulic system, as specified in paragr.
"6.6 Water replacement" on page 35.
Furthermore, all operations envisaged for the pe-
riodic Maintenance must be carried out, see previous
paragraph.
