which seals / o-rings usually cause coffee leaks during brewing?
My Saeco Sirius has been faithfully cleaned, had a few pro servicing sessions & lubrication. It still produces water-filled grounds - not dry pucks, and leaks coffee liquid all over the bottom / table top. I am trying to narrow down what O-rings or seals likely cause this messy leak. Not easy to observe with the machine in operation. Could be large o-ring at Piston. I clean but still get leaks. Will screw adjustments on the BrewGroup part matter on this issue?
