Diagnostics/Solution
Possible causes:
1 - The filter holders are cold.
2 - The coffee has been ground too finely.
3 - The machine's water circuit is dirty
(limescale).
4 - The boiler pressure is below 0.8 bar
(0.08 MPa).
The coffee distributed is tepid, even if the
pressure is found to be normal, between
1 and 1.2 bar (0.1 - 0.12 MPa). In this
case, pressure monitoring is fictitious.
Possible causes:
1- The boiler pressure is more than 1.3
bar (0.13 MPa).
2- The machine is covered by something
that prevents it from cooling down.
3- The machine has been installed in a
position that does not allow air to
circulate.
Possible causes:

the filter is damaged.

Advice
In case 1, keep the filter
holder assembled on the
unit.
In case 2, alter the coffee
grinding.
In cases 3 - 4, call a
specialised technician.
Call a specialised technician
to check the airhole valve.
In the meantime, however,
in order to use the machine,
open the steam tap (Fig. 1 -
pos. 9), the boiler pressure
will go down to zero, and
this will cause the resistance
to step in and increase the
temperature. Carry out this
operation daily when turning
on the machine.
In case 1, call a specialised
technician.
In cases 2-3,
the machine's
conditions.
Case 1 can be solved by
correctly adjusting the coffee
mill.
In case 2, clean the filter
holder or replace the filter.
In case 3, a technician must
be called.
