7 - TROUBLE SHOOTING
Problem
No distribution of steam from
specific tube
Leaks from filter holder
Difficulty in placing the filter
holder on the attachment 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 prob-
lem 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 encrusted.
2 - The filter holder is placed in-
correctly on the unit.
The problem may be caused by
the excessive dose of coffee in
the filter holder.
Once locked onto the unit, the
filter holder handle is further to
the right than usual. The seal un-
der the cup is worn.
Coffee comes out in drops, dis-
tribution time is too long and the
quality of the coffee is not good,
it has a dark cream.
Possible causes:
1 - The coffee has been ground
too finely.
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.
