Hi, I just changed all the brew group o-rings in my Saeco Magic Deluxe and now am having a problem with it ejecting unused pucks. Every used pucks breaks in half with one half staying on top of the brew group. It seems that some of the old puck falls back into the chamber, so that when it goes to press a new one, you can hear it struggling and then it just ejects it. I've tried playing with the grind and doser, but something is still off. Any suggestions?
