Repeated Error Code E01 on Immergas Nike Star 23KW: Ignition Sensor and Control Board Issues

Hello.
I have read a few similar topics regarding immergas ovens. I have recently had a similar problem, because it is the error code "E01". Only that the case for me is as follows.
This error appeared at the beginning of the year, but it was enough to reset it and that's it. After a few days the problem reappeared, but the reset did not help anymore. The stove starts, but gives a spark all the time, then turns off after a while. Reset and the same. A service technician came and replaced the ignition sensor. The stove worked for a few days without any problems and the problem returned. The service technician found the sensor defective and replaced it with a new one. And now, after a few days of trouble-free operation, the problem has reappeared. The stove fires for a few seconds and then goes out. The service technician came to the conclusion that it was the fault of the control board - to be replaced, but the cost is quite high. Anyone can advise something? Thanks in advance.
Greetings.

When you write "ignition sensor", do you have in mind the ionization electrode? If so, measure the current which should be around 5 ?A.

Well, but the service technician does not delete you every time? It should fix the problem first, then delete it. I would also check the voltage in the socket, if something is going crazy, or if there is no voltage on the protective pin.

yes, I mean the ionization electrode. One is for ignition, the other for measuring, so it's about the other. I will try to check the current.

Also check the contacts, they can be too much resistance. I clean this electrode from sediment twice a year. Error 01, for me it appears sporadically at first, then more and more often, until the boiler cannot be turned on.

If someone will need it ...

Lockout - no ignition. The boiler switches on automatically with each demand for heating or domestic hot water production. if
the burner does not ignite within 10 seconds, the boiler starts "blocking - no ignition" (code 01). To delete
"Ignition lock" it is necessary to press the Reset button (1). When it is turned on for the first time or after a long time
period of inactivity of the device, it may be necessary to remove the "ignition lockout". If the situation
repeatedly, call a qualified technician (e.g. Immergas Technical Service).
Overtemperature thermostat lockout . If during normal operation due to
abnormalities, the internal heating of the boiler "becomes" excessive, the boiler is put into a lockout state
overtemperature (code 02). After adequate cooling, remove the "overtemperature block"
by pressing the Reset button (1). If the situation repeats itself frequently, call a qualified technician (e.g.
Immergas Technical Service).
Interference by the smoke thermostat. During operation, if the smoke exhaust duct is not working
properly, the smoke thermostat intervenes, blocking the boiler (code 03 - Yellow). The boiler restarts automatically after 30
minutes when normal conditions are restored without needing to be reset. In the event of three
intervention of the smoke thermostat in less than 2 hours, the boiler after the blockade (code 03 - Red) requires
manual arming by pressing Reset (1). When the malfunction continues, call a qualified technician
technician (e.g. from Immergas Technical Service).
Electromechanical contacts. Appears when the safety thermostat is not working properly,
flue gas pressure switch or system pressure switch (code 04) the boiler does not start; try to reset
boiler, if the irregularity persists, it is necessary to call a qualified technician (e.g. from the Service Center)
Technical Immergas).
Abnormality - installation output probe . If the card detects an abnormality on the output probe
installation (code 05), the boiler does not start; please call a qualified technician (e.g. after sales service)
Technical Immergas).
Abnormality - wu probe If the control unit detects an anomaly on the hot water probe (code 05), the boiler will not
produces domestic hot water; a qualified technician must be called (e.g. from Immergas Technical Service).

System pressure insufficient. The water pressure inside the heating circuit has not been read
(code 10) sufficient to guarantee the correct functioning of the boiler. Check that the system pressure
is between 1 + 1.2 bar.
Unwanted flame. Appears when the reading circuit is dispersed or there is an abnormality in control
flame (code 20); try to reset the boiler; if the irregularity continues, a summon is necessary
a qualified technician (e.g. from Immergas Technical Service).
Insufficient water circulation. Appears when the boiler overheats due to low circulation
primary water (code 27); the reasons may be:
- low circulation in the installation; check that there is no open circuit in the heating circuit and that the installation is OK
completely free of air (deaerated);
- circulation pump blocked; the circulation pump must be unblocked.
If the situation repeats itself frequently, call a qualified technician (e.g. Technical Service)
Immergas) .. With each request for heating or domestic hot water production, the boiler switches on automatically. if
the burner does not ignite within 10 seconds, the boiler starts "blocking - no ignition" (code 01). To delete
"Ignition lock" it is necessary to press the Reset button (1). When it is turned on for the first time or after a long time
period of inactivity of the device, it may be necessary to remove the "ignition lockout". If the situation
repeatedly, call a qualified technician (e.g. Immergas Technical Service).
Wu circuit leakage If an increase in water temperature occurs during heating operation, the boiler
indicates an anomaly (code 28) and reduces the heating temperature to reduce the formation of deposits
limescale in the exchanger. Check that all water system cocks are closed and not
leaking, and in general, whether there are leaks in the system. The boiler resumes normal operation after
system conditions have been restored to optimal conditions. When the malfunction continues, make a call
after a qualified technician (e.g. from Immergas Technical Service).
Lost Communication With Digital Remote Control. Appears after 1 minute of communication loss between
boiler and ZSC (code 31). To reset the error code, remove and restore voltage to the boiler. If the situation repeats
frequently, call a qualified technician (e.g. Immergas Technical Service).

I have removed an inactive link

They apply to a different IMMERGAS stove model, but the codes mean the same.

I had an error 01. It was enough to swap the cables in the plug. Phase with zero swapped and it works.!

Most inquiries about Immergas on OLX or Allegro concern error 01.
This error is no gas, but actually no voltage from the ionization electrode.
The fault may be the electrode itself, which may be dirty (less frequently) the electrode connection (infrequently), the ground polarity in the connection socket and, most often, the MOISTURE in the combustion chamber.
There is no need to waste time and money on replacing the ionization electrode. It is also a pity to measure the currents on the electronic control board.
It is worth unscrewing the burner and checking if there is any leakage from the coil in the combustion chamber.
This is the most common cause.
Unfortunately. The immergas company congratulates itself on the new PLN 3,000. The new furnace costs PLN 4,000.
Congratulations to you Immergas.
I wish you bankruptcy soon!
