Another possible notification occurs when the
DHW exchanger is not able to exchange all the
power delivered by the boiler.
E.g. DHW exchanger blocked by lime scale.
This occurs only when domestic hot water is
requested from the boiler.
Code L1 appears on the LCD display. The back-
ground of the display will flash (Figure 3.8).

To restore correct boiler operation,
contact a technician from an au-
thorised service centre.
Air bubble noises
Check the pressure of the heating circuit and
fill it if necessary, see section "Filling the heat-
ing circuit" on page 16.
Low system pressure
Add more water to the heating system.
To do this, refer to section "Filling the heating
circuit" on page 16.
The user is responsible for periodically check-
ing the pressure of the heating system.
If water needs to be added too often, have the
technical support centre check if there are any
leaks in the heating system or the boiler itself.

USEFUL TIPS
Water leaks from the safety valve
Check if the filling cock is closed tightly (see
"Filling the heating circuit" on page 16).
Check on the pressure gauge that the heating
circuit pressure is not close to 3 bar. Should
this be the case, drain a part of the water from
the system through the air relief valves in the
radiators in order to reduce the pressure to a
normal value.
