Problem in water circuit

I have a deLonghi ECAM 23.460S and for some days now something is not going right.
- when I turn the machine on, the rinse starts but only a few trickles come out
- when I try to make coffee after that, it grinds nicely but then no coffee comes out.

I already checked the pump and it gives water just fine. But after the outgoing hose from the pump, I don't know exactly how to follow the water circuit in both situations. I have already blown through as many hoses as possible, but that has not yet led to a breakthrough. A youtube video explaining how to solve this kind of problem didn't quite fit, because the machine shown didn't have exactly the same components.

I have pictures available from the side, so if someone can point out how the sequence is based on the pictures then I can move on again.

Greetings,

I feel for you. I'm afraid I'm now in exactly the same position, trying to diagnose which part (or parts) may need replacing. The video I looked at dealt with a calcified hose, yet mine seem clear (I descale regularly). I'll post back if I get anywhere. My machine will sometimes start working again... But if not, it ejects dry ground coffee into the hopper and rinses direct to the drip tray, rather than through the nozzles. I'm guessing a valve needs replacing!
