Hi, yes still having issues on every shot. Thats s small leak that if like mine will turn into a gusher. @Paolo_Cortese was going to bring back to base, but despite a recent chase no actual movement on that front.
Happens during pre-infusion when water being pumped into the chamber. After a lot of experiments I was able to improve things for a week or so at a time by adding significant grease to the upper (black/rubber) band on the piston. what @Paolo_Cortese wrote its a big job to replace the entire front mechanism, and needs machine back to his to investigate exact cause which is a right pain hence not happened yet (guessing).
So no real fix currently but will send another email drekly..
That said …. If you ignore the water dribbling everywhere and can angle so doesn’t go in the cup then the coffee is still good ;-)
