6.15 Tips for a good cup of coffee

Wash the filters and filter holders on a daily basis, as indi-
cated in para. 7.7.3 on page 55. 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 the 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, in-
stall a special filter.
Do not to keep large amounts of coffee beans on hand. If
you change the type of coffee, we recommend calling out
the Technician to adjust the water temperature and coffee
grinder.
If the machine has not been used for a certain period of time
(2-3 hours), carry out a few dry runs. Make sure that the ma-
chine is constantly cleaned and periodic maintenance is car-
ried out.
