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. 8 - Fault list (Key LEDs = Off / = On / = Fast flashing)
Indications on boiler panel
Indications on Remote Control Fault Possible cause Cure
Green Yellow Red
A01 No burner ignition
No gas
Check the regular gas flow to the boiler and that the air has
been eliminated from the pipes
Ignition/detection electrode fault
Check the wiring of the electrode and that it is correctly
positioned and free of any deposits
