Change Krups EA 9010 brewing group

I
have a Krups coffee maker (EA 9010) for 3 years. Recently it started to show that the coffee was getting thinner, less coffee ran into the cup, and that the pomace was getting wet. When I opened the machine, I noticed that coffee powder and water were distributed throughout the machine. I checked in various forums, cleaned the inside of the machine, replaced all the seals and cleaned the drainage valve and condenser. After assembly, the machine is tight inside, but now the brewed water no longer runs into the coffee spout, but into the cleaning container for the milk frother. From there into the overflow basin. The ground coffee powder bleeds dry in the brewing group
.

Despite markings it is possible that I have immersed the water hoses. The brewing group has 3 water connections, 1x above and 2x below! Can anyone tell me whether the hose from the drain valve to the brewing group has to be connected to the lower or the upper of the two connections below? Maybe there is even a picture

of it.

Thank you very much in

advance.
