3.4 Troubleshooting
Diagnostics
The boiler has an advanced self-diagnosis system. In case of a boiler fault, the display will flash together with the fault
symbol (detail 11 - fig. 1) indicating the fault code.
There are faults that cause permanent shutdowns (marked with the letter "A"): to restore operation, press the RESET
button (detail 6 - fig. 1) for 1 second or RESET on the optional remote timer control if installed. At this point the display
will show "d4" for about 30 seconds or "d5" for about 5 minutes which indicates the waiting time after which the boiler
will resume normal operation. if the boiler fails to restart, it is necessary to eliminate the fault.
Other faults cause temporary shutdowns (marked with the letter "F") which are automatically reset as soon as the value
returns within the boiler's normal working range.

Cure
Check the regular gas flow to the boiler and
that the air has been eliminated 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 neces-
sary
Check the wiring
Adjust the ignition power
Check the ionization electrode wiring
Check the card
Check the correct positioning and operation
of the heating sensor
Check the circulating pump
Vent the system
Check the card parameter and modify it if
necessary
Check the card parameter and modify it if
necessary
