Keep checking the heating unit pressure which must be between 0.08 and 0.14 MPa
(0.8 and 1.4 bar).
Periodically check the water pressure when coffee is being dispensed: check the pres-
sure indicated on the gauge, which must be in the range of 0.8 - 0.9 MPa (8 and 9 bar).
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.
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 powder in the
grounds is an indication that the coffee is deteriorating. We recommend calling out
the Technician to replace the flat burrs after every 400/500 kg of coffee, or after every
800/900 kg for conical burrs.
Replace the water filter cartridge or regenerate 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.
Check for any gas leaks in the system by passing a soapy solution through the pipes.
We recommend calling out the Technician at least once every three months to replace
the water in the heating unit.
