NOTE
If any alarm appears on the group
display, the machine recognizes that
there is a problem. Refer to chapter 10
to know how to proceed.
WARNING
If the boiler is not completely filled with
water, this could damage the coffee
boiler heating element.
WARNING
To repeat the filling of the coffee boiler
(e.g., after a coffee boiler or group main-
tenance), it is needed to enter again
the FILLING procedure, as described in
chapter 9.
Once the coffee boiler filling procedure
ends, the machine will automatically pro-
ceed with the auto-fill function of the steam
boiler, hence it will start the pump to reach
the correct water level.
If after 90 seconds the water level has not
been reached, alarm A2 appears on the
group display because the motor protec-
tion starts to function.
Furthermore, this system that protects the
motor is also utilised to stop the pump from
working if there is no water available (e.g.,
the upstream tap is closed).
Check the inlet water flowing (e.g., the tank
is correctly filled and placed) and then turn
the machine OFF and ON to continue the
flow of water to the steam boiler.
