Fault E041
Should the pressure value fall below the safety value of 0.3 bar, the boiler
displays the fault code E041 for a transitory time of 10 min.
E040 is displayed.

With a boiler in fault E040:
check that the pressure value reaches 1-1.5 bar by means of a hy-

Once operation is restored, the boiler performs an automatic vent cycle as
described in paragraph "4.10 Filling the heating system and removing air".

If the drop in pressure is very frequent, request the intervention of
the Technical Assistance Centre.
Fault E060
The boiler is working normally, but does not guarantee the stability of the
DHW temperature that is, however, supplied at a temperature of around
50°C. Intervention of the Technical Assistance Centre is required.
Fault E091
The boiler has an auto-diagnostic system which, based on the total num-
ber of hours in certain operating conditions, can signal the need to clean
the primary exchanger (alarm code E091).
Once the cleaning operation has been completed, reset to zero the total
hour meter with special kit supplied as an accessory following procedure
indicated below:
