Thanks for the reply. Meanwhile, I disassembled all the solonoids and did a deep clean, and that solved the issue. It was some internal blockage in the system, nothing to do with the pin hole or the cappuccinatore.

Hello!
I have the same issue, and I have tried even cleaning the air pin assembly. Took it all apart and deep cleaned everything. Still no foam. Do you think it could be the cappuccinatore? It makes a funny sound when dispensing milk.
Thanks
