Help LFGSS coffee-geek hivemind! I've recently changed coffee supplier for my espresso and it's creating weirdness. I don't think I've changed my grind setting but it now seems to be flowing very fast, while also creating enough back-pressure to defeat the grouphead seal and force plain water round the portafilter and into my coffee. What's going on?
