Tips for a good cup of coffee
Wash the filters and filter holders on a daily basis, as indicated in para. 8.7.3 on page 73. The failure to perform
this cleaning operation will negatively affect the quality of the dispensed coffee.
To obtain high-quality coffee, it is important that water hardness does not exceed 6-7°f (French degrees). If the
water hardness exceeds these values, it is advisable to use a water filter or softener. Avoid using a water softener if
the water hardness is less than 4°f.
If the taste of chlorine in the water is particularly strong, install a special filter.
Do not to keep large amounts of coffee beans on hand. If you change type of coffee, it is advisable to contact
the Manufacturer's Qualified Technicians to adjust water temperature and coffee grinder.
If the machine has not been used for a certain period of time (2-3 hours), perform some cycles on empty. Make
sure that the machine is constantly cleaned and periodic maintenance is carried out.

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 powder in the grounds is an indicated that the coffee is
deteriorating. We recommend contacting a Qualified Technician to replace
the grinder blades every 400/500 kg of coffee, or after every 800/900 kg
for conical grinders.
If the grinder automatic wear warning is enabled, follow the instructions
in para. 8.4 on page 71 .
