tchibo cafissimo - no water is flowing from the nozzle into the capsules

Hello, as in the topic there is no water from the nozzle from the capsules, it flies through the return hose to the bottom, probably through the safety valve, the rest works ok, my question is where to look for the fault and what is the solenoid valve for, which is with the return hose, there is voltage on it then when I press the coffee brewing button, what does it open when voltage is applied?

As you can see, it opens when it heats up to release the pressure back down .. It closes when you want to make coffee .. And you say that while making coffee, water escapes through it through the hose?
If I understood correctly, this solenoid valve is to blame ...
At the outset, I suggest taking it out, disassembling it and cleaning it ..

No buddy, the voltage on the solenoid valve appears only when it gives coffee brewing, he opens something in this main heater to which it is screwed on the side for two hexagonal screws, from it comes a hose at the top, return (for excess water) down, which is connected to it on the way a tee and one more tee from the pump with a safety pressure valve and probably the water goes through this safety valve, not up and onto the heater, and then to the tee and down, and poured through a special pouring hole along with damage

Well .. I think you answered yourself - You say that during brewing the water flows to the drip tray through the safety valve. If this is the case, the valve has released and needs to be replaced.

rather, something else is blocking because if the setting is that the water flows through the nozzles for frothing milk, it flows through the hose normally up to the heater and to the right to the nozzle and the nozzle flows out.

The green line, the water to the milk frothing nozzle goes normally, i.e. up and to the left, while it goes up to the coffee brewing nozzle and something blocks it and then releases the safety valve.
I have marked a connection to this solenoid valve for such a dark pink color

Hello, I found a fault, i.e. the culprit was a blocked passage to the coffee brewing nozzle, I pulled out the entire heater from the coffee machine from the side of the brewing water outlet, I put a copper wire and started drilling after connecting the compressor with the blowing nozzle and blowing all the muck outside, greetings
