Hi all.
I recently cleaned my gaggia coffee deluxe group head by removing the shower screen, brew head and seal, gave it a good clean and put it all back together.
However now when the portafilter is full of coffee (properly tamped to correct height) it wont lock in. It cant even get started As the coffee is pressed against the shower screen before the ears can get up into the head.
Does anyone know whats wrong?
