Very clear, thank you.

On the white plastic part that you can see from 1:25 onwards there are two small pins which hold the spring. The spring curls around the right pin and one end of the spwing wire pushes against the left pin. That left pin in my portafilter is loose but I can not tell whether it is a small seperate part or whether it used to be part of the bigger white plastic and has broken off. Do you know whether this is an integral part of the entire white plastic unit?

How to re-assemble it please ?

Can you use none pressurised portafilter with this machine?
