MOD. LIVIA G4
3 - MACHINE DESCRIPTION
3.1 Description of working cycle
The water coming from the tank on the back of the machine, via a vibration pump, passes through a excess
pressure valve regulated to 12 bar (1.2 MPa) and allows the boiler and the exchanger to be loaded. The
boiler water, heated by a resistance, heats the water in the exchanger in turn, from where it is sent to the
unit via an electrically-controlled valve, using a weight, that allows the water to pass through to produce
coffee.

7 - TROUBLE SHOOTING
Problem Diagnostics/Solution Advice
No distribution of steam
from specific tube
The steam tube nozzle is blocked; unblock
it using a pin. This problem is linked to
the fact that the tip of the nozzle enters
the milk.
Clean the steam nozzle after
each use.
Leaks from filter holder Possible causes:
1 -The seal under the cup is worn or en-
crusted.
2 -The filter holder is placed incorrectly
on the unit.
Clean with the brush pro-
vided.
If the problem should arise
again, call a specialised
technician.
Difficulty in placing the
filter holder on the at-
tachment ring
The problem may be caused by the ex-
cessive dose of coffee in the filter holder.
Reduce the amount of coffee
in the filter holder. (Standard
doses for filters are 6 grams
per dose).
Abnormal position of
filter holder once placed
on the unit.
Once locked onto the unit, the filter hold-
er handle is further to the right than usual.
The seal under the cup is worn.
Call a specialised technician
to replace the seal under the
cup.
Coffee flow is less than
usual
Coffee comes out in drops, distribution
time is too long and the quality of the cof-
fee is not good, it has a dark cream.
Possible causes:
1 -The coffee has been ground too fine-
ly.
2 -The coffee in the filter holder is pressed
down too hard.
3 -Too much coffee has been placed in
the filter holder.
4 -The unit shower is blocked.
5 -The filter in the filter holder is blocked.
In cases 1-2-3, the problem
can be solved by adjusting
the grinding and/or dosage
of the coffee.
In case 4, a technician must
be called.
In case 5, clean the filter or
replace it.
Coffee flow is excessive The coffee is distributed too quickly and the
cream is lighter than usual.
Possible causes:
1 -The coffee has been ground too coarse-
ly.
2 -The coffee in the filter holder is not
pressed down enough.
3 -There is too little coffee in the filter hold-
er.
Alter the coffee grinding and/
or dosage.

17
MOD. LIVIA G4
Problem Diagnostics/Solution Advice
The coffee distributed is
too cold
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).
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.
The coffee distributed is
tepid.
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.
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.
The coffee distributed is
too hot
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.
In case 1, call a specialised
technician.
In cases 2-3, restore
the machine's cooling
conditions.
Coffee deposits on the
bottom of the cup
Possible causes:
1- Coffee is ground too finely.
2- The filter holder is dirty on the inside or
the filter is damaged.
3- The coffee mill's grinders are worn.
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.
