Slow flow rate from Gaggia Classic group head (pawb.social)

I've had a Gaggia Classic for a few years and over the last few months I've been having issues with the flow from the group head.

I think it might be an issue with the solenoid valve. There was some guidance I saw online about flicking rapidly from the group head to the steam wand, as this forces water through and clears any blockages. And yes this does seem to work - if I rapidly flick the switches the water suddenly flows a lot faster from the group head. But it's not a permanent fix.

I've descaled it several times. Is there something else I can do, or does the valve need replacing?

Yeah it might be a good idea to take it apart. I don't think the head or screen is the issue, as once the water starts flowing (after using the switching trick) everything flows well through the head. I'll have a look into puck screens though!
