Water circuit of caffeo bistro 960-105

Hello TogetherThis
group I had already saved my Melitta from the bulky waste over 4 years ago. Now it is limping again.
No more coffee came out, instead it ran into the drip tray.
I took the unit apart and put in a new drain valve.
Now I feel like I connected the water hoses wrong ????
When I turn the unit on, the powder compartment light flashes. No water comes down when it heats up. There is just nothing that can be done. But when I turn the unit off it rinses normally, the water runs normally.

Can anyone help me with this? Or is there a drawing of the hoses so I can correct it?

Am grateful for any help ????

Forgotten to connect the plug for the powder compartment? It is in the upper part of the machine.

I did. But I really have the feeling that it's the water hoses. Normally, water should also come out as soon as the machine heats up.

If the message for the powder compartment lights up when switching on, then it can almost only be due to the plug or perhaps a missing magnet in the powder lid
.

It was the cable after all ????
I was so sure I had everything plugged in.
Thanks for your help Schlawi. You are my salvation ????????
Drink now after a long time a real ☕ and hope that esso remainsVgSevgi
