I am newbie to espresso world and I bought a used ECM Giotto 2005 (my second machine after a Gaggia Coffee). I would like change the group gasket and screen to make it clean and rinse it with a detergent.
Can someone give me an advice to how do it ? I see a small Allen screw on the top of the E61 group but I don't know if I need unscrew this to remove the gasket and screen. Can someone explain or post 1-2 pictures to show me this?
Thanks in advance.
