... Sometimes the wire connection plugs become dirty or contaminated due to moisture, corrosion, etc. So just to be sure, find a suitable solvent, electrical contact cleaner would be best, and try to insure that there is efficient, clean electrical contact between the wire end connectors. Inspect both ends of any connecting wires to see if something has come loose.
... all I can think of at the moment.

... Found a reference, something about the drain hose being positioned properly in the back of the washer. ... also door must be correctly closed. ... Another option is to replace the electronic control panel.

Hello there. A belated welcome to AAC! :)

There is a transformer on your control board that is not shown in the photograph It supplies the 220(RMS) voltage your washing machine needs to lock the door. It should be attached to the plastic housing of the control board can't miss it be safe and unplug it. Before measuring the transformer and or replacing the unit!

Yeah the transformer wrapped in green tape there is your problem you confirmed it by your measurement! :)
Let me clear my mind.One of the points of my tester got to touch the metal of the machine and the other one of the pins?? Or both points of the tester have to touch those pins in the red conector in the board??

I don't think there will be a memory card on the circuit board. I think all the required memory will be in the microcontroller.
(The TMPM376FDFG according to the link to information I posted.) I have only briefly looked at this information and it seems there are two signals from the control board to the door lock. One to open it and one to close it. Do you know if the door lock is working ? Did you replace the door lock or just the door lock switch ?
