Lack of steam distri-
bution from the pipe
Leakage from the
portafilter
Too little coffee

too quickly
Diagnostics/solution
The steam pipe nozzle is obstructed,
clear it using a pin.
This problem is caused by immersing
the spout into the milk.
Possible causes:
1- The lower bowl sealing is worn or
encrusted.
2- The portafilter is positioned
incorrectly on the group.
3- The filter in the portafilter is
damaged.
The coffee dispenses drop by drop,
the dispensing time is too long, the
quality of the coffee is not good and
presents a dark cream.
Possible causes:
1- The coffee grind is too fine.
2- The coffee in the portafilter is
packed too tightly.
3- The small nozzle of the group is
obstructed.
4- The filter into the portafilter is

(0.9 Mpa)], or the pump is not
working (volumetric pump ver-
sion).

Possible causes:
1- The grind of the coffee is too
coarse.
2- The coffee in the portafilter is
packed too tightly.
3- The coffee portion in the porta-
filter is insufficient.
