(1) If the shutdown or fault persists, contact an authorised company (e.g. Authorised Service Centre)
(2) The anomaly can only be verified in the list of errors in the "Information" menu
Cause
In the event of request of room central heating or domestic
hot water production, the boiler does not switch on within
the preset time. Upon appliance commissioning or after
extended downtime, it may be necessary to eliminate the
block.
During normal operation, if a fault causes excessive over-
heating internally, the boiler goes into overheating block.
During normal operation, if a fault causes excessive flue gas
overheating, the boiler blocks
The P.C.B. detects a fault on the gas valve supply. Check its
connection. (The fault is detected and displayed only in the
presence of a request). Upon confirming that the fault does
not concern the gas valve, you must replace the P.C.B. if the
fault does not disappear after pressing the Reset button.
The board detects an anomaly on the flow NTC probe.
The board detects an anomaly on the domestic hot water
NTC probe. In this case the antifreeze function is also in-
hibited
Water pressure inside the central heating circuit that is suf-
ficient to guarantee the correct operation of the boiler is not
detected.
Boiler status / Solution
Press the Reset button (1)
Press the Reset button (1)
Press the Reset button (1)
Press the Reset button (1)
The boiler does not start (1)
In this case the boiler continues to
produce domestic hot water but not
with optimal performance (1)
The anomaly can be reset 5 times
consecutively, after which the
function is inhibited for at least one
hour. One attempt is gained every
hour for a maximum of 5 attempts. By
switching the appliance on and off
again, the 5 attempts are re-acquired.
Check on the boiler pressure gauge
that the system pressure is between
1÷1.2 bar and restore the correct
pressure if necessary.
