Reset function
In order to reset the boiler's operation in the event of a fault, it is necessary
WRSUHVVWKH5(6(7EXWWRQ
At this point, if the correct operating conditions have been restored, the
boiler will restart automatically.
There are a maximum of 3 consecutive attempts at interface, when used
up it is possible to unlock the boiler by cutting off and reconnecting the
electrical supply.

If the reset attempts do not activate the boiler, contact the Technical
Assistance Centre.
For fault E041
If the pressure drops below the safety threshold of 0.3 bar the boiler displays

If the drop in pressure is very frequent, contact the Technical Assistance
Centre.
For fault E060
The boiler is working normally, but does not provide any stability of the
domestic hot water temperature that, in any event, is supplied at a
temperature of around 50°C. The intervention of the Technical Assistance
Service is required.
For fault E091
The boiler has an auto-diagnostic system which, based on the total number
of hours in certain operating conditions, can signal the need to clean the
primary exchanger (alarm code E091).
Once the cleaning operation (made with special kit supplied as an
accessory) it is necessary to reset to zero the total hour meter following
procedure indicated below
