Reset failures
The buttons preceded by the symbol allow scrolling
through the menu or changing of data; the other buttons
are used directly for that function.
DISPLAYING THE EXISTING FAILURES
When the “Present failures” function from the “program-
ming” menu is displayed, press the confirm button “ ” to
display the error code of the current failure; then keep
pressing button “ ” to display the error code of the next
present failure.
If no failures are present, when pressing the confirm
button “ ” the message “No Failure” is displayed.
The possible failures are indicated in the following cases:
Failures regarding water supply can vary according to the
type and presence or not of the waste overflow warning
device inside the cabinet. The possible cases are:
AIR-BREAK FAILURE
The machine will lock if after dispensing water corre-
sponding to 150 pulses of the volumetric counter the
microswitch has not signalled the lack of water.
BOILER FAILURE
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 FAILURE
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 FAILURE
The data contained in the EEprom (i.e. the chip that stores
the setting variations) is wrong and must be retrieved from
the Eprom, thus losing all statistics information.
The message “INITIALISE” will start blinking on the display.
WATER EMPTY FAILURE
Models with water supply from the mains
The machine locks if the air-break microswitch 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 machine is equipped with a liquid waste container
(housed in the cabinet) fitted with an overflow warning
device, the solenoid valve will stay triggered until water
from the mains is resumed.
Models with water supply from a tank/with support
cabinet
The machine locks if the water level in the tank falls to less
than approximately 300 cc. The tank’s pump starts for 60
seconds to attempt correcting the failure.
WATER LEAK FAILURE
Models with water supply from a tank/without support
cabinet
If water is requested by the air-break without having been
used (selections, cleaning etc.) and the configuration
does not include the liquid waste container (housed in the
cabinet) fitted with an overflow warning device, the ma-
chine will block further water requests.
IMPELLER FAILURE
Failed computation of the volumetric counter within a max.
given time.
COFFEE UNIT FAILURE
This failure is due to a mechanical lock of the unit or when
the unit is not present. The machine is not locked, but all
coffee-based selections are disabled.
COFFEE EMPTY FAILURE
If after a period of 15 seconds of grinding coffee a dose is
not obtained, all coffee-based selections are disabled.
COFFEE DOSE RELEASE FAILURE
If after releasing the ground coffee dose the microswitch
of the coffee doser unit indicates the presence of coffee
in the dosing chamber, all coffee-based selections are
disabled.
