THE FOLLOWING OPERATIONS SHOULD BE PERFORMED EXCLUSIVELY BY QUALIFIED AND
AUTHORISED PERSONNEL.
Alarm Machine status Solution
(AL03) Alarm: no water
(if sensor present) Machine stopped or waiting for an auto-
matic start-up attempt
Check water supply, check for water leaks in the
circuit, check operation of water inlet valve and
clean water filter, check position of sensor.
(AL04) Alarm: ice bin
probe faulty Machine stopped Check probe-board connection, check probe in-
tegrity, check that the ohm value read is correct,
replace probe - By checking beforehand that
there is space in the bin, 30 consecutive min-
utes of ice production can be started by press-
ing the button.
(AL05) Routine mainte-
nance request Machine continues to work Call technical assistance for periodic main-
tenance (reset the message by pressing the
button for 10 seconds)
(AL06) High temperature
at condenser outlet Machine stops, condenser fan remains
on to lower the condenser temperature,
or water valve remains open in case of
water condensation. (once it has cooled
down, the machine restarts making a
few attempts to see if the alarm is no
longer present, then it stops permanent-
ly)
Check cleanliness and ventilation of condenser,
check that the condenser fan is turning, check
position of condenser probe; in water-cooled
versions, check the water supply and operation
of the water inlet valve.
(AL07) Condenser probe
alarm Condenser probe faulty or outside
allowed value range, the machine works
with continuous ventilation or water inlet
always activated.
Check condenser probe-board connection,
check that the ohm value read is correct, re-
place probe.
(AL08) Evaporator probe
(if present) Evaporator probe faulty or outside al-
lowed value range, the machine stops.
Check evaporator probe-board connection,
check that the ohm value read is correct, re-
place probe.
(AL09) Blackout - No
power supply The machine will resume operation in
the state before the power failure.
Check the electrical connections and power
source. (To remove the alarm message, press
once to silence the buzzer, press again to
remove the message if within the first minute,
second press only if the minute has already
passed).
"
(AL10) High pressure
alarm The machine stops, the condenser
fan remains on to lower the condenser
temperature, or the water valve remains
open in case of water condensation.
(once it has cooled down, the machine
restarts making a few attempts to see
if the alarm is no longer present, then it
stops permanently)
Check cleanliness and ventilation of condenser,
check that the condenser fan is turning, check
position of condenser probe; in water-cooled
versions, check the water supply and opera-
tion of the water inlet valve, replace maximum
pressure switch.
(AL11) Discharge pump
alarm Machine stops and periodically attempts
to drain water, for a limited number of
times
Check that the water drainage line is not
clogged, check operation of drainage pump,
check cleanliness of level sensor, check dis-
charge tray outlets.
