It is not possible to release the alarm before the end of the post-purging unless the boiler's power supply is
displayed and is followed by a post-purging of 5 minutes at the fan's maximum speed. It is not possible to release
the alarm before the end of the post-purging unless the boiler's power supply is switched off.

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 tempera-
ture 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.
The intervention of the Technical Assistance Service is required.
