[Solved] Is the appearance of the A01 error in the Beretta QUADRA II cooker the fault of the control board?

Hello, I have a problem with my Beretta brand gas boiler. It is displaying error A01 which is a flame problem. I have the closed combustion chamber version. I would like to add that I have a second boiler, with a leaking exchanger as a parts donor, unfortunately it is not the closed chamber version. The problem, to my non-professional eye, is the fan not working. As soon as the cooker is switched on, an A01 error pops up. After entering the chamber and creating the vacuum that the fan should generate, the cooker does not give the error, but also does not provide a spark and does not open the gas valve. I have swapped all the probes, and generally everything that matched, from the other cooker, with no results. The fan itself is functional, when voltage is applied it starts. I am betting on damage to the control board. I also swapped it, but on this cooker it does not switch on, only the power light flashes faster. Is it possible that the control board from the open chamber version does not fit the closed chamber version?

Hey. I don't have this cooker, but I do have an older Beretta and, like you, it didn't light the flame because the fan didn't switch on. The culprit was a faulty relay on the control board responsible for switching on the fan, simply the contacts were burnt out. Several cookers have had the same problem, maybe it is the same for you? Also check the pressure switch (vacuum switch).
Best regards.

. I was also thinking about this. If I sent you a picture of this board would you be able to tell which relay it is? As I said, I have a second board from which I can re-solder, but I don't know much about electronics, and to re-solder all of them is probably pointless?

I replaced all of them (3 pieces in total, I think, on the PCB) for peace of mind. No problem available at e.g. Farnell.
Have a nice day.

Lest I leave the post unfinished. It was exactly as Marcin described. The cooker is running like crazy, the relays changed from the plate I had. I will buy 2 new sets in the spring and replace them both. The topic is closed
