If the capacity of the chamber will not be increased for the cases described in this man-
ual, the espresso group can malfunction (displaying errors “Opening group”, “Closing
group” and blockage of coffee bean based drinks), as well as mechanical failures.
The espresso group allows you to regulate the space in the chamber for intake of
ground coffee from the dosing mechanism. In case of setting the dosing mechanism
into positions 5 or 6 it is necessary to increase the capacity of the chamber by setting
thestopperringinpositionB(seeg.5.14).
