Cause

Boiler status / Solution

0E2

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.

(2) (1)

0E13

Maximum N° of reset

Number of allowed resets that have already performed.

Attention: 

it is possible to reset the anom-

aly up to 5 consecutive times within 15 

minutes. (1) By switching the appliance 

on and off the 5 attempts are re-acquired.

0E25

P.C.B. error

An error is detected on the P.C.B. and the boiler does not start up

(2) (1)

0E30

Flow NTC probe in 

short circuit

The board detects a short circuit on the flow NTC probe.

(2) (1)

0E31

Flow NTC probe 

outside the operating 

range

The board detects an open contact on the flow NTC probe.

(2) (1)

0E32

DHW NTC probe in 

short circuit

The board detects a short circuit on the DHW NTC probe

(2) (1)

0E33

DHW NTC probe 

outside the operating 

range

The board detects an open contact on the DHW NTC probe.

(2) (1)

0E34

Low power supply 

voltage

This occurs when the power supply voltage is lower than the allowed 

limits for the correct boiler operation. 

(2) (1)

0E37

Insufficient system 

pressure or flow

If the system flow rate 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. Make sure that the boiler input 

is suitable for the installed circuit. (2) (1)

0E43

Return NTC probe in 

short circuit

The board detects a short circuit on the return NTC probe

(2) (1)

0E44

Return NTC probe 

outside the operating 

range

The board detects an open contact on the return NTC probe.

(2) (1)

0E45

Flue NTC probe in 

short circuit

The board detects a short circuit on the flue NTC probe.

(2) (1)

0E46

Flue NTC probe outside 

the operating range

The board detects an open contact on the flue NTC probe.

(2) (1)

0E81

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

(2) (1)

0E98

Simple cascade com-

munication anomaly

Occurs if the communication between the display boards breaks down

Check the bus’ electric connection.

Perform the Auto detection.

Check whether the software versions 

match. (2) (1)

0E99

Internal communica-

tion anomaly

In the event of simple cascade, even in the case of a communication 

error between the display boards.

Check the boiler’s wiring.

Check the bus’ electric connection.

Perform the Auto detection in the event 

of simple cascade installation.

(2) (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.

FE94

Display board anomaly

An error is detected on the display's P.C.B..

(2) (1)

FE95

Shared common flow 

probe short-circuited 

or out of range

The board detects an incorrect value on the flow NTC probe or “P38” 

parameter not set correctly.

(2) (1)

FE96

External probe 

anomaly

An anomaly is detected on the external probe.

Check the boiler configuration, check 

the external probe (2) (1)

FE97

Configuration error

P.C.B. configuration error.
It may occur also in the event of replacement of the electronic boards 

with an incorrect model.

Check the configuration parameters.

Perform the Auto detection.  (2) (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.
