6.7.2 Water circuit filling
The machine automatically activates the pump
and starts filling the espresso coffee boiler.
IMPORTANT:
Before powering the machine, thus starting the
automatic installation:
1. Make sure that the water softener is filled with
water and the air bubbles removed.
2. Load the reachable columns of the cup holder.
NOTE:
If the filling of the boiler is not successful, the
machine cannot be set into service. A failure
message will be shown on the display. Should it
be the case, eliminate the cause and reset the
error recorded (section 8 Programming and
maintenance menu), then repeat the automatic
installation, switching the machine on once again.
After a testing phase on start-up, the machine
automatically fills the water circuit of the tray
equipped with a float and of the brew group boiler.
During this stage, the heating element of the
boiler remains automatically off. If the machine
detects that the boiler is already filled, it passes
to the heating stage.
The sequence of operations will be:
- insert the special key in the machine cover
switch
- on start-up of the machine, the filling of the
tray equipped with a float starts automatically,
while the machine carries out the automatic
testing phase.
During testing, the following components start
up in the given order:
- the brew group, so as to reach the correct
start-up position
- the cup holder, so as to load the first cup
column into the releasing device.
During the setting-up phase:
- the coffee boiler and the water tank are filled
up
- once the water circuit is filled, the heating
phase starts up, thus switching on
automatically the boiler heating element.
Recommended solutions
When the boiler is completely filled, wash the
mixer repeatedly in order to remove possible
residues from the hydraulic circuits. NB: see
section 8 - Programming and Maintenance
menu, in order to start test or cleaning brewing.
- After performing these operations, wait a few
minutes for the machine to reach service
temperature and make beverages available.
