3.5 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 11 - fig. 1) indicating the fault code.
Certain faults cause permanent boiler shutdowns (marked with the letter “

”): to restore operation, press the RESET

button (detail 6 - fig. 1) for 1 second or RESET on the optional remote timer control if installed; if the boiler fails to start,
it is necessary to firstly eliminate the fault.
other faults (indicated with the letter “

”) cause temporary shutdowns that are automatically reset as soon as the value

returns within the boiler's normal working range.
