The infusion element has moving parts that are activated by a 24 Vdc motor that moves a
crank which moves the coffee from the dosage element to the piston. At the same time it also
moves a lever that activates a micro switch; this indicates the position of the infusion element
to the control board.
At rest, the infusion element cannot move from its position as it is held by the piston. Before
extracting the piston the black extraction button (C7) should be pressed (with the machine
switched on). On pressing the extraction button the infusion element will position itself in the
coffee loading position. After this the two levers that hold it can be turned and it can be
removed with ease.
In the infusion element support there is another micro switch that deactivates when the
infusion element is removed. This way, the control board knows whether the infusion element
is correctly positioned or not.
To replace the infusion element into the machine it may be in any position and it does not
matter if it moves while out of the machine. It only needs to be replaced and the two holding
levers fixed. When the presence micro switch is activated, the infusion element motor will
position it correctly.
