Problem
The flow of coffee is excessive
The coffee dispensed is too cold Possible causes:
The coffee dispensed is tepid
The coffee dispensed is too hot
Troubleshooting/Solution
The coffee is dispensed too
quickly and the cream is lighter
than usual.
Possible causes:
1 - The coffee is ground too
coarsely.
2 - The coffee in the filter holder
has not been pressed firmly
enough.
3 - The dose in the filter holder
is too small.
4 - The pressure released by the
pump is too high (> 10 bar
- 1 MPa).
1 - The cups are cold.
2 - The filter holders are cold.
3 - The coffee is ground too
finely.
4 - The machine water circuit is
dirty (limescale).
5 - The boiler pressure is lower
than 0.8 bar (0.08 MPa).
6 - The group is cold.
The coffee dispensed is tepid
even if the pressure is normal,
between 1 and 1.2 bar (0.1
– 0.12 MPa). In this case, the
pressure detected is false.
Possible causes:
1 - The boiler pressure is higher
than 1.3 bar (0.13 MPa).
2 - The machine is covered by
something that prevents it
from cooling.
3 - The machine was installed in
a position that does not al-
low air circulation.

MOD.
In cases 1-2-3, adjust the grind-
ing and/or dosing of coffee.
In case 4, contact a technician.
In case 1, use the cup warmers.
In case 2, keep the filter holder
mounted on the group.
In case 3, adjust the grinding of
the coffee.
In cases 4-5-6, call a special-
ised technician.
Call a specialised technician to
check the bleed valve. Mean-
while, to use the machine, open
the steam tap (Fig. 01; pos. 1);
the boiler's pressure will drop to
zero, thus activating the resistor
and increasing the temperature.
Perform this operation daily
when turning on the machine.
In case 1, call a specialised
technician.
In the cases 2-3, reset the ma-
chine cooling conditions.
