Hi, I'm a bit helpless, I got a Krups F889 from a colleague for fun with the words it doesn't work anymore.
The brewing unit jams after about 3 centimeters and is very difficult to turn, after reading a bit I suspected that it was not maintained.
So everything screwed on and the brewing unit revised (
) with the seals of Komtra.
So far the test run ran so well by hand, but I noticed that the piston jams as soon as you force the movement with more force and then cants in one position. At the
uppermost position the piston
cants and you can only move it again if you move it back a little bit. I once made a small video which illustrates the problem:

Automat presses of course with full force to the top position and then this always gets stuck, I tested after a full dismantling. Did
I do something wrong with the revision?
Is this a known bug or who can give me a hint to fix it?
Maybe I should use the normal gaskets instead of the smooth-running gaskets, but that's not the problem.
