TROUBLESHOOTING GUIDE
The machine is provided with a program of self-diagnosis, that allows to visualize
on the display the messages of breakdown or machine stopped :
Message
Description
Probable cause
ERR. CUP-RELEAS.
during the cup-releasing, the board has not
received the change of state of the cup-releaser
micro switch.
Fuses, cup-releaser motor, cup-releaser micro
switch, electronic board.
ERROR ARM 0
The electronic board has not received the “sugar
position” of the cup -arm signal by the relative
sensor on the cup-station board.
Fuses, cup blocked in the cup-arm, cup-arm
motor, position sensor, electronic board.
ERROR ARM 1
The electronic board has not received the “cup
position” of the cup -arm signal by the relative
sensor on the cup-station board.
Fuses, cup blocked in the cup-arm, cup-arm
motor, position sensor, electronic board.
ERROR ARM 2
The electronic board has not received the
“supply position” of the cup -arm signal by the
relative sensor on the cup-station board.
Fuses, cup blocked in the cup-arm, cup-arm
motor, position sensor, electronic board.
ERROR GROUP 1
the coffee-group has not reached the “supply
position” given by its right micro switch.
Fuses, group right micro switch, group motor,
electronic board.
ERROR GROUP 0
the coffee-group has not reached the “normal
position” given by its left micro switch.
Fuses, group left micro switch, group motor,
electronic board.
ERR. COFFEE FLOW
During espresso supplying, the board has not
received signals from the flowmeter.
Fuses, too finer coffee, coffee pump, coffee
electro valve, flowmeter, electronic board.
ERR. SOLUB.FLOW
During soluble supplying, the board has not
received signals from the flowmeter.
Fuses, solubile pump, solubile electro valve,
flowmeter, electronic board.
ERROR GRINDER 1
During the coffee grinding, the board has not
received the signal given by the doser-switch in
the maximum time of 25 seconds.
Too fine coffee, fuses, doser micro-switch,
grinder motor, grinder blocked by something
hard, electronic board.
LACK OF CUPS
The board doesn’t receive the signal from the
cups sensor.
Lack of cups, cups sensor, electronic board.
LACK OF WATER
The board doesn’t receive the signal from the
float.
Lack of water, float, water container micro
switch, electronic board.
ERROR BOILER 1
The board has not received the programmed
value temperature from the boiler probe in the
maximum time of 15 minutes.
Safety thermostat, boiler heating element,
electronic board.
EMPTY GROUNDS!
The coffee grounds decounter has reached the
programmed value.
Empty the grounds and execute the quick
function nr.5.
ERROR EXECUTIVE
At the power-on, the board has not received
signals by the payment payment, Executive or
MDB, programmed.
Payement system, cables, electronic board..

HYDRAULIC CONNECTION
INSIDE TANK
The machine is already set for the inside tank working.
WATER SYSTEM CONNECTION (OPTIONAL)
• disconnect the silicon pipe, which comes from the tank, from the limestone
filter.
• connect the silicon pipe coming from the water resevoir to the filter.
• connect the connector with the two grey wires coming from the water reser-
voir to the connector with two grey wires of the machine.
• disconnect the wires of the float and connect the black and green wires com-
ing from the water reservoir to the black and green wires into the machine.
• check that the net-system pressure doesn't overcome the 2 bars, otherwise it is
necessary to install a pressure reductor.
• Connect the water inlet tube to the inlet electrovalve with a ¾ " fitting.
