coarse.
2 – The coffee in the filter hold- The coffee in the filter hold- The coffee in the filter hold-
er has not been pressed
enough.
3 – The dose in the filter holder
is scarce.
4 – The pressure supplied by the
pump is high (> 10 bar – 1
MPa).
Possible causes:
1 – The cups are cold.
2 – The filter holders are cold.
3 – The grinding of the coffee is
too thin.
4 – The machine's water circuit
is dirty (limestone).
5 – The boiler's pressure is low- The boiler's pressure is low- The boiler's pressure is low-
er than 0.8 bar (0.08 MPa)
6 – The group is cold.
The coffee supplied is warm if
the pressure is normal, between
1 and 1.2 bar (0.1 – 0.12 MPa).
In this case, the pressure value
is not correct.
Possible causes:
1 – The boiler's pressure is
higher than 1.3 bar (0.13
MPa).
2 – The machine is covered by
something that
cooling.
3 – The machine was installed

Advices
In cases 1-2-3 adjust grinding
and/or dosing of coffee.
In the 4th case, a technician
must be consulted.
In the 1st case, use the cup
warmers.
In the 2nd case, keep the fil-
ter holder assembled on the
group.
In the 3rd case, adjust the grind-
ing of the coffee.
In cases 4-5-6, call a special-
ized technician.
Call a specialized technician to
check the exhaust valve. Mean-
while, to use the machine, open
the steam tap (Fig. 01; pos 1);
the boiler's pressure will drop to
zero, thus causing the enabling
of the resistor and the increase
of temperature. Perform this op-
eration daily when turning on
the machine.
In the 1st case, call a special-
ized technician.
In cases 2-3 reset the machine's
cooling conditions.
