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)
0A4 Air pressure switch
During the heat request phase, the board detects the stuck/open contacts
of the air/flue pressure switch or a fan malfunction.
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)
0A8
Flame circuit anomaly
During the ignition phase an anomaly was detected on the electronic
flame control circuit and the boiler switches off.
Press the Reset button (1)
0A9
Gas valve electric
circuit anomaly
The board detects an anomaly in the gas valve circuit. Before replacing
the board, verify the absence of short circuits on gas valve and related
connector.
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)
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)
0A37
Insufficient system
pressure
If the system pressure is too low the boiler switches off.
Check on the boiler pressure gauge (1)
that the system pressure is between 1÷1.2
bar and restore the correct pressure if
necessary.
(2) (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).
(2) If normal operating conditions are restored, the boiler re-starts without having to be reset.
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.
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”.
Example: “0A1” anomaly
Anomaly on Master boiler = 0A1
Anomaly on Slave boiler = A1
Slave boiler anomaly displayed on Master boiler
= 1A1
