FILTER HOLDERS
filters and/or filter holders, as required.
Check the ground coffee dose (between 6 and 7 grams per time) and check the de-
gree of grinding. Burrs must always have sharp cutting edges; too much powder in
the grounds is an indication that they are deteriorating. We recommend contacting
GRINDER-DISPENSER
the Technician to replace the flat burrs after every 400/500 kg of coffee, or after
every 800/900 kg for conical burrs.
If the automatic burr wear warning is enabled, follow the instructions in para. 8.6
on page 55.
Replace the water filter cartridge or regenerate the water softener at the frequency

indicated by the manufacturer or whenever the automatic regeneration alert is

replace the water in the heating unit.
