Leaking from hydraulic valve vent. ⇐ Beko

[fa11er]

Hello. Machine Beko DFN05310W. Worked great for 2 years. Now, when drawing water, water flows from the upper ventilation of the hydraulic distributor. You can get rid of this only if you reduce the water supply pressure by closing the valve on the cold water inlet pipe. But the dishwasher takes a very long time to fill with water. Before this, everything worked with the tap as open as possible. I checked the inlet hose for blockages - everything is fine, the filter at the inlet to the dishwasher is clean. The hydraulic distributor itself was removed, blown, and washed. Everything seems to be ok there. What could it be? I tried to search on the Internet. There is absolutely nothing leaking in this part. I am attaching a video:
