2 - Possible problems due to failure to provide maintenance
2.1 - Pod holder setting (Only for model 510)
Using the machine normally leads to wear of the sealing washers in the closure of the pod
holder unit. This leads to coffee coming out from the side when it is delivered.
To restore the sealing of the lining, proceed as follows:
1 – Lift the side command lever of the pod holder unit so you
can introduce the 2.5 mm Allen wrench into the screw
fastening seat (12A)(see fig.4).
fig.4
2 – Loosen the screw.
3 – Turn the hexagonal adjusting ring nut clockwise (12) in
order to close the unit tighter, or counterclockwise in order to
make the closing looser.
4 – Again carry out some closing tests using the side lever
and deliver some coffee in order to make sure that it is
properly adjusted and that the washer seals.
5 – Tighten the fastening screw again
This adjustment can be carried out several times.
When the O-Ring liner becomes too flat or is worn out, replace it as shown on figure 5a-
5b.
