3.4 Troubleshooting
Diagnostics
The generator is equipped with an advanced self-diagnosis system. In case of operation problems or
anomalies, the control unit of the single boiler shell activates flashing of the corresponding display (with
fault identification code) and a 230Vac output (to which a visual or acoustic signalling device can be con-
nected. See the electrical connections section).
Faults marked with the letter “A” cause permanent generator shutdown. To restore operation, press the
“R” (reset) key on the generator.
Faults marked with the letter “F” cause temporary shutdowns that are automatically reset as soon as the
value comes back within the generator’s normal working range.
The following table gives details for solving problems signalled by the generator. Interventions on the
unit must only be carried out by Qualified Personnel such as those of the FERROLI Customer Technical
Assistance Service. For interventions on the unit that involve opening the generator, always request the
assistance centre.
Burner does not light
