DIVAPROJECT C24
4.4 Troubleshooting
Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault, the 3 LEDS will indicate the fault code.
There are faults that cause permanent shutdown: to restore operation, press the RESET button for 1 second (ref. 5 - fig. 1) or RESET on the optional remote timer control if installed;
if the boiler fails to start, it is necessary to firstly eliminate the fault indicated in the operation LEDs.
Other faults cause temporary shutdowns which are automatically reset as soon as the value returns within the boiler's normal working range.
Table. 3 - List of faults (Legend - LEDs
Fault
No burner ignition
Overtemperature protection activation
Flame present signal with burner off
Fume thermostat activation (boiler operation is prevented for 20
minutes after fume thermostat intervention)
Low system pressure
Delivery sensor fault
DHW sensor fault
Exchanger protection activation.
(The LEDs flash alternately)
Faulty card
Card not electrically powered

Cure
Check the regular gas flow to the boiler and that the air has been elimi-
nated from the pipes
Check the wiring of the electrode and that it is correctly positioned and
free of any deposits
Check the gas valve and replace it if necessary

Check the correct positioning and operation of the heating sensor
Check the circulating pump
Vent the system
Check the ionisation electrode wiring
Check the card
Check the thermostat
Check the wiring
Change the flue
Fill the system
Check the sensor
Check the wiring or replace the sensor
Check the wiring or replace the sensor
Check the circulating pump
Vent the system
Replace the card
Check the power supply
Replace fuses
