14.0 ALARMS
ALARM LIST POSSIBLE CAUSE SOLUTION
Faulty cell probe Possible fault of the cell probe Contact the authorized technical service centre. The
machine will run with a temporary temperature
value calculated as the average of the needle probe
and the evaporator probe.
Faulty core probe Possible core probe fault.
Core probe not connected. Check the probe plug is inserted correctly, in case
disconnect the probe and gently clean the contacts.
Do not force the connector during the insertion to
avoid damaging the contacts. If the problem
persists, contact the authorized technical service
centre.
Faulty humidity probe Anomaly or failure in the detection of humidity.
The alarm may appear if a program with humidity
is started after a blast chilling or freezing cycle. With the alarm active, Levtronic will not use the
humidifier to manage humidity. Warm Levtronic up
with a manual cycle at 40° without humidity to dry
the probe. If the problem persists, contact the
authorized technical service centre.
Faulty evaporator probe Possible fault of the evaporator probe Contact the authorized technical service centre. It is
possible to continue using Levtronic, defrosting and
fan management will not be optimized.
Faulty condenser probe Possible fault of the condenser probe (Levtronic) Contact the authorized technical service centre. It is
possible to continue using the appliance,
performance will not be optimal.
Faulty electronic valve probe Possible failure of the refrigerant gas
management electronic valve. Contact the authorized technical service centre.
Faulty LP transducer Possible failure of the low pressure transducer. Contact the authorized technical service centre.
Faulty HP transducer Possible failure of the high pressure transducer. Contact the authorized technical service centre.
Cell high temperature protection The cell temperature exceeds 100°C. The compressor is activated in cooling mode, if the
temperature does not drop, disconnect Levtronic or
Modi Active from the power supply and contact the
authorized technical service centre.
Cell high temperature It activates if the setpoint is not reached after 4
hours of continuous compressor operation Check that there has been no excessive load of hot
product, check that the condenser of the machine is
clean, check the ventilation in the technical
compartment is correct.
Core probe high temperature The core probe temperature is too high. If the product it is in is too hot, remove it and let
the product cool for a few minutes.
Power board high temperature. The power board is operating beyond the
maximum temperature limits.
Check the ventilation in the technical compartment
is correct. Stop the cycle and let the appliance cool
down.
Door open The door is open
Close the door, if the alarm persists, contact the
technical service centre.
Communication with power board
interrupted The control board cannot communicate with the
power board. Disconnect the appliance from the mains and
contact the authorized technical service centre.
Water filter replacement The cartridge of the water filter upstream from
the humidifier has reached the end of its life
(Levtronic) Cartridge replacement. Do not use programs with
humidity or steam when the cartridge is empty: risk
of failure of the steam generation system.!
Clean the condenser The condenser is dirty and does not guarantee
the correct cooling of the cooling system. See par. 15 Cleaning the condenser
Faulty humidifier water load Faulty humidifier water load (Levtronic) Contact the authorized technical service centre and
close the water stop-cock.
Faulty heating humidifier Faulty heating humidifier (Levtronic) Contact the authorized technical service centre.
High pressure
HP switch intervention Excessive pressure detected by the high pressure
transducer. Check that the condenser is clean, the appliance
has enough space to evacuate the heat from the
condenser and/or that the product inserted is not
too hot. For water-cooled appliances, check the
correct water supply. If the problem persists,
contact the authorized technical service centre.
Interrupted communication with
electronic valve Programs are interrupted due to the inability to
control the electronic valve. Disconnect the appliance from the power line for 10
seconds, if the problem persists, contact the
authorized technical service centre.
