On the SAMSUNG's site it says that is is related to the excessive fluctuation of the power supply voltage. I turned it off and now it doesn't turn on anymore.

Analyzing the main board, I've checked low voltage power supply and it seems to work, it outputs 37V (or something like that, I don't remember the exact value). On some connectors I've measured 5V and 12V.

In the same board there is also a relay connected to the input that, when active, powers other components (like the door lock) and the main rectifier circuit that powers the inverter.
If I bypass that, the machine turns on and after a couple of seconds I can hear the relay activating. At this point I can remove the bypass and the machine stays on. (I haven't tried to run a cycle)

At this point I'm not sure on what is the problem. The description of the error code makes me think that it has something that measures some kind of voltage? (I don't know what it checks and where), so maybe that is faulty? Or I'm missing something else?

I've attached a simplified schematic  that I've drawn while trying to understand how it works.

Moreover, I've found a service manual online that have some details on the wirings: https://www.manualslib.com/manual/279727...

Do you have any suggestions? Thanks.
