Hi,
I need to clean the group head on my old gaggia coffee deluxe machine, but the damn thing seems to be near welded in. I've tried twisting it with some pliers into the two near central holes and scraping around the edge where it sits against the gasket, but with no success.
Can anyone suggest a way to shift this before I beat it to death with something and probably damage it in the process?
Thanks,
dolcevita
