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 - 0.9 MPa (8
and 9 bar).

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.

GRINDER-DISPENSER
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
contacting the Technician to replace the flat burrs after every 400/500 kg of coffee,
or after every 800/900 kg for conical burrs.
