Glückwunsch! ;-)

You did not disassemble the brewgroup? If so, the issue must be the screws. It' s no problem, if you opened the blue marked screw, it just holds both parts of the gear sledge together. I would remove the brew group again and control the sledge, the blue screw and the three remaining screws: one in the left below the blue one, and two in the lowest(!) holes on the right side. There are empty holes remaining! Turn the big wheel of the brewgroup and proof the function: does it move smoothie and easy? If you opened the brew group, my guess is a broken seal or some other issue.

The main purpose of this guide is serving as prerequisite for other guides.

Au ja. Du kannst so was selbst ausbessern. Einfach auf “Übersetzen" gehen und loslegen.

Thank You!! The spring came out and I looked for a way to reinsert it. So I led a thread through its opening (so it couldn´t jump away), and compressed it with pliers. So it was easy to put it in.

I think those 5,5 mm mean the length (!) of the screws. The heads are normal little Philipps, perhaps #00 or #000.

I did this fix many times: the balls are on top oft the springs! They do fit into the corresponding holes in the underside of the cone, as you can clearly see in the picture. If the cone is stopped by e.g. a little stone, the balls come out of the holes saving the motors life.

Open it and have a look!

This guide is used by many other guides as first step! Don´t laugh about it.

This means the length oft the screws. The screwhead is Phillips.
