3.4 Troubleshooting
Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault, the display will flash together
with the fault symbol (detail 20 - 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 8 - fig. 1) for 1 second or use the RESET on the optional remote timer control if installed; if the boiler fails
to start, it is necessary to first eliminate the fault.
Other faults (marked with the letter “F”) cause temporary shutdowns that are automatically reset as soon as the value
returns within the boiler's normal working range.
