Howdy gang,
I think that I ground too fine and tamped too hard!
When I locked the portafilter into place and pulled down the lever to preinfuse, all seemed ok, until the lever was stalled and locked pointing at about 60 degrees from horizontal. After a moment the portafilter blew off and the lever sprang back. Unfortunately one of the shower screens and an o-ring blew out, into the drip tray!
From an infogram I found I think it's the bottom o-ring that's come out.
What should I do? Has anybody experienced one of these "blowouts" of sorts?
Can the old o-rings be popped back into place? I figure It's best to replace the screens but should I replace the o-rings too?
Your advice is much appreciated.
