How to remove stucked brewing unit

Why does it stuck? Try to move the unit using the test mode, until the arrows on the yellow main axis match. This is the position to pull out the unit. If this doesnt work you have to use a somewhat rustic method: about two cm left from the yellow axis is a hole. Insert a Torx T10 screwdriver and loosen the screw on the opposite side. Hopefully you now can pull (pulling rather strong) out the unit. The inlet nozzle on the opposite side should now be stuck in the unit. Remove it. Good luck, hope it works - but there ist no guarantee.
