the CPU board controls the machine operation. It is the core of
machine programmes and it is secured to the frame by means of
four supports; the display cable transmits the exchange of signals
with the keyboard and the display arranged in the door (see 05.02.
and 05.04.); the temperature probe cable is separated from the
machine wiring so as not to hamper any removal of the probe;
the boiler heating element led turns on whenever the boiler heating
element is activated; the two fuses protect the + 5 V and + 24 V
board power supply;
the display board secured inside the door will accommodate the
signals of the selection keyboard and display the messages; a flat
cable will connect it with the CPU (see 05.04.);
the expansion board, in E machines only, is necessary to control
the coffee brewer motor and the grinder;
some versions can heat the brewing chamber of the coffee unit;
this board, which is protected by a fuse, controls the operation of
the heating element;
