FILTERS AND FILTER HOLDERS
Check the condition of the lters. Check for any damage on the edge of the lters
and check whether any coffee grounds settle in the coffee cup, and replace the
lters and/or lter 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
calling out the Technician to replace the at burrs after every 400/500 kg of coffee,
or after every 800/900 kg for conical burrs.
