GALATEA DOMUS
MOD.
Problem
The coffee dispenses too
abundantly
The coffee is too cold
The coffee is tepid
The coffee is too hot
Diagnostics/Solution
The coffee dispenses too quickly and the
cream is clearer than usual.
Possible causes:
1- The grind of the coffee is too coarse.
2- The coffee into the filter holder is not
pressed enough.
3- The coffee dose into the filter holder is
insufficient.
4- The pressure of the pump is too high
[>10 bar (1 Mpa)] (volumetric pump
version).
Possible causes:
1- The filter holders are cold.
2- The coffee grind is too fine.
3- The water circuit of the machine is dirty
(milestone).
4- The boiler pressure is lower than 0,8
bar (0,08 Mpa).
The coffee is tepid, although the pressure
is normal between 1 and 1,2 bar (0,12
Mpa).
In this case, the pressure measurement is
dummy.
Possible causes:
1- The boiler pressure is higher than 1,3
bar (0,13 Mpa).
2- The machine is covered with something
that prevents its cooling.
3- The machine has been installed in a
position that prevents air circulation.

Suggestions
In cases 1-2-3, it is necessary
to adjust the grinder correct-
ly. In case 4, it is necessary to
call a technician.
In case 1, keep the filter hold-
er mounted on the group.
In case 2 change the coffee
grind.
In cases 3 - 4 call a skilled
technician.
Call a skilled technician to
check the relief valve. Mean-
while, in order to use the ma-
chine, open the steam valve,
(Fig. 01; pos. 9) the boiler
pressure will drop to zero: in
this way, the heat elements
will be connected and the
temperature will increase.
Carry on this operation every
day when turning on the ma-
chine.
In case 1 call a skilled tech-
nician
In cases 2-3 reset the ma-
chine cooling conditions.
