basket.

NOTE:

If the filling of the boiler is not successful, the
machine cannot be set into service. The
'installation failed' message on the display will
be shown. Should it be the case, eliminate the
trouble and repeat the automatic installation,
after repairing the trouble (Section 8 - SERVICE,
failure repair).
After carrying out the DIAGNOSIS phase, the
machine fills the water circuit of the float tank
and the brew group boiler in a fully automatic
mode. In this phase, the heating resistances of
the boilers are automatically switched off. When
the machine detects that boilers are loaded, it
automatically proceeds to the HEATING phase.

The sequence of operations will be:

- insert the special key in the door switch

- at machine start-up, the water tank with float
automatically starts to fill up, while the
machine carries out the automatic diagnosis.

During the diagnosis, the following components
are engaged:

- the brew group, to ensure the right initial
position.

- the cup basket to load the first column of
cups in the release device.

Then, during the initialisation phase:

- the water tank and the instant product boiler,
if any, fill up

- 2 complete brewings of very long coffee are
performed automatically in order to fill the
brew group boiler.

- once the water circuit filling is completed, the
heating phase starts and the boiler heating
resistances automatically switch on.

E16-CAPACITY alarm is just a simple warning,
which does not block the machine, and indicates
that the pump – solenoid valve circuit has
detected a progressive decrease in water
capacity. It can also indicate that the volumetric
counter (fan) is defective or the existence of
calcareous deposits on the solenoid valves. This
condition means that a E04-PUMP failure is
going to occur.

Other warnings that do not block the machine
are also foreseen and have the purpose of
advising the user that the regeneration of resins
of water softener, the grinders and filters is
necessary.
The number of counts beyond which the
regeneration is deemed necessary is set in the
