Hi everyone! I’ve been owning a Vostok machine for over an year now and I enjoy everything about it except the safety sleeve which has been giving me headaches since the beginning…
My current issue with the safety sleeve is the fact that it seems to spritz water with a lot of force through the screw whole no matter what I try, which ends up digging a whole the coffee puck, as shown in the picture below…
I’d appreciate any ideas to mitigate this from one of you with more experience than me with this machine… Paolo even sent me a second safety sleeve but it’s behaving the same way…

I also have a puck screen which seems to help in this regard but I would still like to figure out a solution to get rid of this altogether, since flushing the group head causes a mess at the moment since a lot of water ends up on the touchscreen due to this spritzing…
