Washer Beko WTV8744XW Door lock cycling

[bc546kkkk]

Hi Beko washing machine is in working order, while it has one defect, when turned on its cycling door lock, opens and closes it repeatedly and after a few cycles it stops in the closed position. The washing cycle goes normally. Replacing the lock did not help. Wires to the lock are ok. Controller, no damaged components visually and after measuring resistors, triacs, transistors and diodes. Voltages ok, once E29 appeared. Other than that, it works normally. After the wash cycle, the same thing happens opens and closes several times and finally does not open. Maybe someone has an idea?

So assumed missing energy to solenoid.
You must measure how far back it goes.

Voltage checks must also be as close to the end as possible.
There can always be a bad contact somewhere in between.
