boiler filling has been exceeded.
2 = Time-out boiler pressure set-point: the time
limit to reach boiler pressure set-point has been
exceeded
3 = Electronic board E06 12Vdc short: short circuit
in the electronic board E06
4 = Capacity level sensor 12Vdc short: capacity level
sensor supply has short-circuited. (*).
5 = Pressure transducer 12Vdc short: pressure tran-
sducer supply has short-circuited.

the supply of volumetric counters.
7 = 5Vdc push-button panel short: the push-button
panel has short-circuited.
8 = Transducer/probe short on output signal: short
circuit on output signal from the pressure tempe-
rature probe / transducer.

from the temperature probe/transducer has been
interrupted.
A = Absence of volumetric counter impulses group
1: the volumetric counter of the first group is not
transmitting impulses to the electronic board.
B = Absence of volumetric counter impulses group 2:
the volumetric counter of the second group is not
transmitting impulses to the electronic board (*).
C = Absence of volumetric counter impulses group
3: the volumetric counter of the third group is not
transmitting impulses to the electronic board (*).
(*) Only for predisposed machines.
The failures identified by numbers 1 to 9 block
machine operation. Apart from the failure being in-
dicated on the display, the push-button panel LED
will flash simultaneously informing the user of the
malfunction.
After having identified and resolved the failure,
switch the machine off and then on again for normal
operation
NOTE: The problems identified with the letters A, B
and C do not interrupt the functions of the machine.
They are identified on the display and during dispen-

abrasive devices, such as steel wool, metal
brushes, needles, etc. or general detergents
(alcohol, solvents, etc.)
When necessary, use special detergents
for coffee machines that can be bought in
