2.5 FAULT AND ANOMALY SIGNALS
The boiler signals any anomalies using a code shown on the boiler
display (11) according to the following table:
Error
Code
Anomaly signalled Cause Boiler status / Solution
01 No ignition block
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. Clogged condensate drain.
Press the Reset button (1)
02
Safety thermostat
block
During normal operation, if a fault causes excessive over-
heating internally, the boiler goes into overheating block. Press the Reset button (1)
03
Flue safety thermostat
block
During normal operation, if a fault causes excessive flue gas
overheating, the boiler blocks
Press the Reset button (1)
04
Contacts resistance
block
The P.C.B. detects a fault on the gas valve supply. Check its
connection. (the anomaly is detected and displayed only in
the event of a request).
Press the Reset button (1)
05
Delivery probe fault
The board detects an anomaly on the flow NTC probe. The boiler does not start (1)
06 DHW probe fault
The board detects an anomaly on the domestic hot water
NTC probe. In this case only the antifreeze function is in-
hibited
In this case the boiler continues to
produce domestic hot water but not
with optimal performance and with
possible scalding risk(1)
08 Maximum N° of resets Number of allowed resets already performed.
The anomaly can be reset 5 consecu-
tive times, after which the function is
inhibited for at least one hour and it is
possible to try once every hour, for a
maximum of 5 attempts. By switching
the appliance on and off again, the 5
attempts are re-acquired
10
Insufficient system
pressure
Water pressure inside the central heating circuit that is suf-
ficient to guarantee the correct operation of the boiler is not
detected.
Check on the boiler pressure gauge
that the system pressure is between
1-1.2 bar and restore the correct
pressure if necessary (1)
16
Fan failure (flue gas
pressure switch)
It occurs in the event of failure of the flue gas pressure
switch (electrical contact closed) or fan speed sensor.
NOTE: the flue gas pressure switch contact is checked only
when the burner is ignited.
If normal conditions are restored the
boiler restarts without having to be
reset (1)
20 Parasite flame block
This occurs in the event of a leak on the detection circuit or
anomaly in the flame control unit.
Press the Reset button (1)
23
Return probe
anomaly
The board detects an anomaly on the return NTC probe The boiler does not start (1)
24
Push button control
panel anomaly
The board detects an anomaly on the pushbutton panel.
If normal conditions are restored the
boiler restarts without having to be
reset (1)
(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
