filter holder on the at-
tachment ring
Abnormal position of
filter holder once placed
on the unit.
Coffee flow is less than

Diagnostics/Solution
The steam tube nozzle is blocked; unblock
it using a pin. This problem is linked to
the fact that the tip of the nozzle enters
the milk.
Possible causes:
1 - The seal under the cup is worn or en-
crusted.

on the unit.
The problem may be caused by the exces-
sive dose of coffee in the filter holder.
Once locked onto the unit, the filter hold-
er handle is further to the right than usual.
The seal under the cup is worn.
Coffee comes out in drops, distribution
time is too long and the quality of the cof-
fee is not good, it has a dark cream.
Possible causes:
1 - The coffee has been ground too fine-
ly.
2 - The coffee in the filter holder is pressed
down too hard.
3 - Too much coffee has been placed in
the filter holder.
4 - The unit shower is blocked.
5 - The filter in the filter holder is
blocked.

low (< 9 bar – 0.9 MPa) or null.
