I’ve had the Gaggia Classic for 5 years. I replaced the gasket and seal a few years back. I back flush 1-2 times per year. I know I should be doing it more often but I get lazy.
I just took apart the gasket and noticed a lot of build up on this doohickey part. Soaked it in cafiza for half hour but couldn’t get most of the gunk off. Anybody with knowledge on espresso machines have any advice on whether this is normal wear and tear or if I need to replace or soak overnight? Appreciate any feedback.
