Problem
The flow of coffee is
excessive
The coffee dispensed is
too cold
The coffee dispensed is
warm
The coffee dispensed is
too hot
Coffee deposits on the
bottom of the cup
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 delivered by the pump is
too high (>10 bar - 1 MPa).
Possible causes:
1 - The filter holders are cold.
2 - The coffee is ground too finely.
3 - The machine water circuit is dirty (lime-
scale).
4 - The boiler pressure is lower than 0.8
bar (0.08 MPa).
The coffee dispensed is warm 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 allow air circulation.
Possible causes:
1 - the coffee is ground too finely.
2 - the filter holder is dirty inside or the fil-
ter is damaged.
3 - The grinding discs are worn.
4 - High pump pressure (> 10bar - 1
MPa).

Advice
In cases 1-2-3, adjust the
grinding and/or dosing of
coffee.
In case 4, contact a techni-
cian.
In the 1st case, keep the filter
holder inserted on the group.
In the 2nd case, adjust the
coffee grinding.
In cases 3-4, call a speciali-
sed technician.
Call a specialised technician
to check the bleed valve. Me-
anwhile, to use the machine,
open the steam tap (Fig. 01;
pos. 9); the boiler's pres-
sure will drop to zero, thus
activating the resistor and
increasing the temperature.
Perform this operation daily
when turning on the machi-
ne.
In the 1st case, call a specia-
lised technician.
In the cases 2-3, reset the
machine cooling conditions.
Case 1 can be solved by
adjusting the grinder cor-
rectly.
In case 2, clean the filter hol-
der or replace the filter.
In cases 3-4, contact a tech-
nician.
