MANUAL INSTALLATION (direct function)

Press the installation button “3” to fill the hydraulic system,
even with the air-break full.

RESETTING FAILURES (direct function)

Press the failure reset button “8”; the message “Running”
is displayed for a few seconds and all present failures are
reset.

DISPLAYING THE CURRENT FAILURES

When the “Present failure” function from the “program-
ming” menu is displayed, press the confirm button “ ” to
display the error code of the current failure;
then each time button “ ” is pressed the error code of the
next failure is displayed (if present). If no failures are
present, when pressing the confirm button “ ” the mes-
sage “No Failure” is displayed.
The possible failures are indicated in the following cases:

AIR-BREAK

The machine will lock if after dispensing water correspond-
ing to 150 pulses of the volumetric counter the micro-
switch has not signalled the lack of water.

BOILER

The machine will lock if after 10 minutes of heating from the
machine start, or from the last selection, the boiler fails to
reach the operating temperature.

COIN MECHANISM

The machine will lock if it receives an impulse longer than
2 seconds on a validator line or there is no communication
with the serial coin mechanism for more than 30 seconds.

RAM DATA

The data in the EEprom (i.e. the chip that stores the setting
variations) contains errors and must be retrieved from the
Eprom, thus losing all statistics information.
The message “INITIALISE” will be shown on the display.

WATER FAILURE

Models with water supply from the mains

The machine locks if the air-break micro-switch is closed
for more than 10 seconds. When pressing a selection
button the water inlet solenoid valve is triggered to check
the water flow from the mains.

Models with water supply from the tank

The machine locks if the water level in the tank falls to
below approximately 300 cc.

CUP FAILURE (for automatic models only)

When the empty cup column micro-switch opens, the
column shift motor is activated. If after one full turn, the
micro-switch is not closed the message “Cup failure” is
displayed and the machine locks.

WATER LEAK

If water is requested by the air-break without having been
used (selections, washing, etc.) the machine will block
further water requests.

IMPELLER FAILURE

Failed computation of the volumetric counter within a max.
given time.

COFFEE UNIT FAILURE

Due to mechanical blocking of the unit.
The machine is not locked, but all coffee-based selections
are disabled.

COFFEE FAILURE

If after a period of 15 seconds of grinding coffee a dose is
not obtained, all coffee-based selections are disabled.

WASTE CONTAINER FAILURE

If the machine is equipped with a liquid waste container
(housed in the base cabinet) and the overflow warning
device is triggered, the machine locks.

COFFEE RELEASE FAILURE

If after releasing the ground coffee dose the micro-switch
of the coffee doser unit indicates the presence of coffee in
the dosing chamber, all coffee-based selections are disa-
bled.

CUP RELEASE FAILURE (for automatic models only)

If after releasing one cup the positioning micro-switch is
not triggered the control software disconnects the power
from the release motor and the machine locks.

WATER FAILURE

The machine locks if the air-break micro-switch is closed
for more than 10 seconds.
When pressing a selection button the water inlet solenoid
valve is triggered to check the water flow from the mains.
If the failure is not reset automatically, it will be necessary
to restart the machine to be able to reset the failure again
by pressing a selection button.

CHANGER FAILURE (MDB only)

The change-giver coin mechanism is not working or does
not communicate.

BILL VALIDATOR FAILURE (MDB only)

The bill accepter is not working or does not communicate.

CASHLESS FAILURE (MDB only)

The key or magnetic card reader is not working or does not
communicate.
