- remove the front and back slides and the capsule ejector
levers;
- remove the 4 fastening screws with a screwdriver and
remove the piercing filter;
- disassemble the upper piston;
- remove the filter and the piston seal.
Soak all components removed from the unit in a solution
of boiling hot water and coffee machine detergent for
approx. 20 minutes.
Thoroughly rinse and dry all parts, then reinstall them in
the reverse order of disassembly, taking particular care
that:
- the two reference notches match and that the coffee unit
is inserted;
- check the efficiency of the seals, lubricating them with
food safe grease.
The piercing filter must be replaced in any case.
Important notice!!!
During reassembly, check that the handle pin of the
ratiomotor is correctly engaged in its seat.
The integrity of the machine and compliance with the
standards of the relevant systems must be checked at
least once a year by qualified personnel.
Before starting any maintenance operations requiring
parts of the unit to be removed, the machine must
always be switched off.
The operations described below must be carried out
only by personnel who have the specific knowledge of
the machine functioning from a point of view of elec-
trical safety and health regulations.
INTRODUCTION
To ensure correct operation for a long period, the machine
must be subjected to regular maintenance.
The following sections contain the procedures and the
maintenance schedule, which are only a general indica-
tion, as they greatly depend on the operating conditions
(e.g. water hardness, environmental humidity and tem-
perature, type of product used, etc.).
The procedures described in this chapter are not exhaus-
tive of all maintenance operations to be carried out.
More complex operations (e.g. boiler descaling) should be
carried out by qualified technicians only having specific
knowledge of the machine.
To prevent oxidation or the action of chemical agents, the
stainless steel and varnished surfaces should be kept
clean by using mild detergents (solvents must not be
used).
Under no circumstances should water jets be used to
clean the machine.
ESPRESSO UNIT MAINTENANCE
The piercing filter must be replaced every 5,000 selec-
tions. In any case it will be necessary to disassemble and
sanitise the upper filter, the piercing filter and the brewing
chamber at least every 6 months. After 5,000 selections,
when accessing the “Filler” menu the message “Check
filter” is displayed with the number of selections made
since the last replacement. After replacing, the counter is
reset with button “ ”.
Maintenance is carried out as follows:
- remove the Teflon hose from the upper piston, connected
to the boiler and to the tube for hydraulic control of the
piston, undoing the colour rings (see Fig. 24);
- unscrew the knob securing the unit to the bracket and
remove the coffee unit;
- remove the stop rings and take the rod out;
- remove the ring and take the ejector piston out;
