2.6 TROUBLESHOOTING.
The boiler will let you know of any anomalies by
the flashing screen and code. There are different
types of codes that can be divided up as follows:
- “0Axx” for resettable anomalies (fig. 2-9).
(Before resetting the anomaly you will need to
wait for the boiler to finish its post-ventilation
function, which lasts approximately 60 sec-
onds).
- “0Exx” and “FExx” for non-resettable anoma-
lies.
The “xx” suffix stands for the error code de-
scribed in the following tables.
Error
Code
Anomaly signalled Cause Boiler status /Solution
0A1 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.
Press the Reset button (1)
0A2
Parasite flame block
This occurs during the power-on phase in the event of a leak on the
detection circuit or anomaly in the flame control unit.
Press the Reset button (1)
0A3 Overheating block
During normal operation, if a fault causes excessive overheating inter-
nally, the boiler goes into overheating block.
Press the Reset button (1)
0A5 Fan signal anomaly This occurs if the fan speed is incorrect. Press the Reset button (1)
0A7
Flue temperature
anomaly
If the boiler fails, the flue circuit will provide an excessively high
temperature reading and the boiler will switch off.
Press the Reset button (1)
0A9
Gas valve electric
circuit anomaly
The board detects an anomaly in the gas valve circuit Press the Reset button (1)
0A15
Flow and return NTC
probe temperature
detection incorrect (in
stand-by)
With the boiler in stand-by, the board detects an anomalous difference
between the NTC probe flow and return temperatures. The error may
be caused by a failure in one of the two probes
Press the Reset button (1)
0A16
Poor thermal flow
NTC probe contact
During boiler operation the board does not detect a change in the flow
NTC probe temperature. The error may be caused by a poor thermal
probe contact or a system with excessive thermal inertia.
Press the Reset button (1)
0A17
Poor thermal return
NTC probe contact
During boiler operation the board does not detect a change in the return
NTC probe temperature. The error may be caused by a poor thermal
probe contact or a system with excessive thermal inertia.
Press the Reset button (1)
0A18
Flow and return NTC
probe temperature
detection incorrect
If the board detects a sudden drop in temperature on one of the two
NTC probes (flow and return), it will report an anomaly. This may be
caused by the failure of one of the two probes
Press the Reset button (1)
0A21 P.C.B. error An error is detected on the P.C.B. and the boiler does not start up Press the Reset button (1)
0A30
Flow NTC probe in
short circuit
The board detects a short circuit on the flow NTC probe. Press the Reset button (1)
0A31
Flow NTC probe
outside the operating
range
The board detects an open contact on the flow NTC probe. Press the Reset button (1)
0A37
Insufficient system
flow
If the system flow is too low for a certain period, the boiler will detect
the anomaly.
Check the flow meter, check the system.
Press the Reset button (1)
0A43
Return NTC probe in
short circuit
The board detects a short circuit on the return NTC probe Press the Reset button (1)
0A44
Return NTC probe
outside the operating
range
The board detects an open contact on the return NTC probe. Press the Reset button (1)
0A80
Flow and return NTC
probe connection error
If the electrical connection between the two NTC probes is switched
around, the board will detect the anomaly (it may be necessary to wait
3 minutes for the error to be detected).
Press the Reset button (1)
(1) If the block or anomaly persists, contact an authorised company (e.g. Immergas Technical After-Sales Service).
Simple cascade: in case of simple cascade,
anomalies will be displayed on the master boiler
(without the “0” suffix on the Slave boiler) and
slave boiler anomalies are displayed on the mas-
ter boiler with suffix “1”.

xample: “0A1” anomaly
Anomaly on Master boiler = 0A1
Anomaly on Slave boiler = A1
Slave boiler anomaly displayed on Master boiler
= 1A1
