I have recently replaced the group seal in my em6900r. Now if the portafilter isnt all the way over to the right and the dosing isnt perfect the portafilter leaks, not a great deal but enough to be annoying.
Has anyone else had this problem?
Is it possible that the new group seal is slightly thinner than the origanl fittment?
Both the old and new seals were of the blue variety, the origanl seal had a chank blow out hence the need for a replacement.
