Starbucks Saeco Italia sup021 coffee dispenser stuck problem

Hi
Open the front door. Remove the driptray. On the left back side of the brew group, there is a single screw. Remove the screw. Grab the handle and pull carefully, but firmly. The brew group should come out. There is a piece that remains in the machine. Slide the piece down and to the right and it will come off. Insert the piece into the hole on the backside of the brew group with the clip up. Tighten the screw and move brew group back into position. If your brew group did not come out call a service center.
To return the brew group to the centered position, you first need to drop the funnel. To do this look on the opposite side of the brew group from the handle. At the top you will see an object that looks like a sharks fin. Push the "Press" button and the shark fin moves up and down. If you follow this piece down you will see 2 horizontal bars on the brew group body. Push your finger between. these 2 bars and the funnel will drop. Now you can push the puck slide on the left side down and to the center. If you look down through the funnel you should see a piston. This should be centered in the funnel. If not just push the slide to the right until it does. Push the press button and you are now ready to reinsert the brew group in to the machine. First
you must close the door and turn on the machine without having the brew group in. You will hear the motor turn on and when it stops completely, open the door and insert the brew group.
Done
