Problem with aeg caffee perffeto

Hello, dear.
I have the following problems with my aeg caffee perffeto.
First the thermoblock broke which I let change now but I have a new problem with making coffee comes the water from the steam nozzle but not a drop from the coffee spout. But also no water is drawn out of the water tank and if only very little. The pump is also quite quiet during the brewing process. I am grateful for your help because I am now completely helpless. Unfortunately I already had some problems with this machine. Love greetings

There could be damage to the valve for hot water... It seems like it's always open.

Hello
maybe I made a mistake during assembly...
which valve could it be? I first suspected the BG of leaking somewhere. Greetings
