Reset function
To restore boiler operation, press “
ENTER
” from the error message screen. 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 a release by the REC10CH. In case of
all the attempts are exhausted the definitive fault E099 occurs on the display. The boiler will
need to be unlock 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
the fault code “E041 - WATER TRANSDUCER FILL THE SYSTEM” for a transitional time
of 30 seconds during which it is possible to open the external filling tap until the pressure is
between 1 and 1.5 bar.

If the drop in pressure is very frequent, contact the Technical Assistance Centre.
For fault E060:
the appearance of this error, on only heating models with water tank with
probe connected, prevents DHW operation.
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 has been completed, reset to zero the total
hour meter with special kit supplied as an accessory following procedure indicated below:
