DIVAPROJECT F24
4.4 Troubleshooting
Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler anomaly, the 3 LEDS will indicate the fault code.
There are faults that cause shutdown: in order to restore operation it suffices to press RESET for 1 second (ref. 5 - fig. 1) or perform a RESET on the optional remote timer control if
this is installed. If the boiler fails to start, you must first resolve the fault indicated on the display.
Other faults cause temporary shutdowns which are automatically reset as soon as the value returns within the boiler's normal working range.
Table. 9 - List of faults (Legend Leds
Fault

Air pressure switch (fails to close contacts
within 20 sec. of fan activation)
Low system pressure
Delivery sensor fault
DHW sensor fault
Exchanger protection activation.
(The LEDs flash alternately)
Faulty card
Card not electrically powered
