3.4 Troubleshooting
Diagnostics
The boiler features an advanced self-diagnostic system. In the case of an fault in operation, the display flashes
and the code identifying the fault appears. The faults marked with the letter
“A”
cause the permanent shut-
down of the boiler. To reset operation the boiler must be restarted manually, pressing the
“R”
(reset) button.
The faults marked by the letter
“F”
cause temporary shut-down and are reset automatically as soon as the
value returns within the boiler’s normal operating range.
The following table lists a number of indications for resolving the faults signalled by the boiler. Adjustmens
on the appliance must only be carried out by Qualified Personnel, such as the personnel from the FERROLI
Customer Technical Service Centre. For any operations on the appliance or which require the opening of the
boiler, always request the assistance of the service centre.
