Checks and maintenance

To ensure perfect safety and efficiency of the
machine over time, it is necessary to carry out main-
tenance. In particular, it is advisable to ask the
Technical Service to carry out an overall check
of the machine at least once a year.
Checks
MACHINE
Using the machine display, check that the indicated pump
pressure is around 8-9 bar.
Check that the boiler pressure indicated on the display is
consistent with a programming value.
In case of anomalies, contact the Technical Support
Service.
FILTER HOLDER FILTERS
Check the wear of the filters, if there is damage to
the edges, and if coffee grounds are getting into the
cup. If necessary, replace the filters.
GRINDER-DOSER
Check the dose of the ground coffee, which should
be about 6-7 gr. at a time, and adjust the amount
as necessary.
Check the degree of grinding and modify as required.
Check the grinders for wear: they should be replaced
if there is too much powder in the ground coffee.
SOFTENER
Carry out regeneration of the softener (for the
manual softener).
Check that there is salt in the container (for the
softener in the automatic version).
All maintenance operations must be carried out
after unplugging the machine from the power
!
supply, closing the water and completely cooling
off the machine.
We recommend the use of suitable protective
gloves.

If the problem cannot be resolved, turn the machine
off and contact Technical Service. Do not attempt any
!
sort of repairs. The descaling of the machine must be
carried out by professional technicians to ensure that
such operation does not lead to release of hazardous
materials for food use.
