er has not been pressed
enough.

pump is high (> 10 bar – 1
MPa).
In cases 1-2-3 adjust grinding
and/or dosing of coffee.

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.
The coffee supplied is too hot Possible causes:
1 – The boiler’s pressure is
higher than 1.3 bar (0.13
MPa).
2 – The machine is covered by
