Problem
No distribution of steam
from specific tube
Leaks from filter holder
Difficulty in placing the
filter holder on the at-
tachment ring
Abnormal position of
filter holder once placed
on the unit.
Coffee flow is less than
usual
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.
2 - The filter holder is placed incorrectly
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.
6 – The pressure supplied by the pump is
low (< 9 bar – 0.9 MPa) or null.

Advices
Clean the steam spout after
each use.
Clean with the brush pro-
vided.
If the problem should arise
again, call a specialised
technician.
Reduce the amount of coffee
in the filter holder. (Stand-
ard doses for filters are ~ 6
grams per dose).
Call a specialised technician
to replace the seal under the

In cases 1-2-3, the problem
can be solved by adjusting
the grinding and/or dosage
of the coffee.
In cases 4-6, a technician
must be called.

replace it.
