error message will be displayed. The faults description screen
is automatically displayed once the display illumination time
has elapsed without any button being pressed.
For fault E041:
if the pressure drops below the safety threshold
of 0.3 bar the boiler displays the fault code “E041 - WATER
TRANSDUCER LOAD THE SYSTEM” for a transitional time
of 30 sec
during which it is possible to open the external filling
tap until the pressure is between 1 and 1.5 bar.

If the pressure drops frequently, 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 heat
exchanger. The intervention of the Technical Assistance
Centre is necessary.

DESCRIPTION OF TYPE OF ALARM
E021
iono alarm
These are temporary alarms that if they occur several times in an hour they become definitive;
the alarm E097 is displayed and is followed by post-purging for 45 seconds at the fan’s maximum
speed.
It is always possible to release the alarm before the end of the post-purging.

E085
combustion fault/high CO
These are temporary alarms that if they occur several times in an hour they become definitive; the
last error to occur is displayed and is followed by a post-purging of 2 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.
E094
combustion fault/high CO
E095
combustion fault/high CO
E058
mains voltage fault
These are temporary faults that restrict the ignition cycle.
E065
current modulation alarm
E086
obstruction fumes alarm
Temporary fault reported during the post ventilation. It is maintained a post ventilation of 5 min at
maximum fan speed
3. HOW TO...
3.1 HOW TO TOP-UP THE SYSTEM
PRESSURE
The system pressure must be checked periodically to ensure
the correct operation of the boiler. The system pressure is
shown at the top of the LCD display or can be read on the
gauge located on the underside of the appliance. When the
boiler is at room temperature, the system pressure should be
approximately 1.0 bar.
If the pressure requires ‘topping-up’ use the following instructions
as a guide.
- Locate the filling valve connections (usually beneath the
boiler, see fig. 2).
- Attach the filling loop to both connections.
- Open the filling valve slowly until you hear water entering the
system.
- Close the filling valve when the pressure gauge (on the boiler)
reads between 1 and 1.5 BAR.
- Remove the filling loop from the connections.
