Whirlpool DWF 405 does not start washing ⇐ Whirlpool

[smokxx]

Good afternoon
The symptoms are: when I turn it on, it seems to drain water, then it starts to fill up with new water, but at some point it switches to a strange mode - it makes noise for a second, then something clicks and makes a sound, as if it is draining a little water, is silent for a second (even less) and then again - it makes noise, clicks, drains.
Before it all started, the car suddenly fell silent in the middle of the wash, I opened the door - there was the water level. I restarted it, and to be honest, I don’t remember how that wash ended, but then the car no longer wanted to start, it blinked twice, signaling water in the pan. There really was water there, they drained it, but it’s not clear where it came from.
Two masters looked and independently said that the "control unit", "brains" was faulty.
The control unit (which is below) is visually in order, I checked all the resistances - they are in order. What else to check, triacs, zener diodes? How to check them in general?
Maybe it’s not this control unit at all? Doubts gnaw at me.
I can make a video in principle, it’s just that now it’s all disassembled, the control unit is separated.

The service center offers a new motherboard for 4400 plus firmware for 500 rubles, and after two months with prepayment o_O
