Saeco Primea touch Plus cappuccinatore

Hey everyone, I got my hands on a very beaten up Saeco Primea touch plus that I decided to fix myself. Long story short everything seems to work now but the cappuccinatore.
For some reason it doesn't dispense milk and I am not sure why. Everything has been cleaned up(manually and also using the cleaning procedures).
What happens when I try to dispense milk is that I get a lot of steam and nothing more, meanwhile I can hear the stepper working during the process but no joy. Anyone that has experienced this issue and can help?

The problem is certainly already solved. Nevertheless, an answer. If the lid of the water tank is wet afterwards, it is due to the lip seal of the steam inlet. This small seal is very sensitive and is also often installed the wrong way round by the service department. The lip opening must face outward.

Must still specify this. When the milk tank is removed, there are 2 nozzles on the wall behind it. The upper nozzle is meant. The seal must be changed correctly there.
