• Check, by activating the components individually
on the manual control panel, that the level signal
does not show any anomalies (%).
• wash the group
•
clean/replace the coffee filter
• use a coarser grind
•
calibrate the machine correctly on the basis of
the coffee/recipe.
• check that there are no external elements in the
grinders
• check that the measure grinder is working (pick-
up current and fuses)
•
use a finer grind
