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?

In my experience, this is a sign that the solenoid has something inside it. Your best bet is to take it apart and do a full descale.

This video takes you through the whole process. https://www.youtube.com/watch?v=N9i-EH7qXOc

It's not as big a task as it might seem, and it will definitely get everything flowing again
