Remove the dredge drawer. Open the door. On the left side of the brewing unit, and towards the back of the brew group, there is a single screw. Remove the screw. Grab the handle and pull carefully, but firmly with a quick ****. The brew group should come out. There is a piece that remains in the machine. Slide that 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.
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. 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. (You can insert your key into the hole in the front and twist the key to return the brew unit to the center. Line up the 2 diamonds and it centered) If you look down through the funnel you should see a piston. This should be centered in the funnel. If not, locate the slide on the left side of the brew unit,(it should be hanging down, a flat rectangular piece attached to the cylinder) and 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, but you must have your drip tray and dredge drawer in. Turn the machine on. You will hear the motor turn on and when it stops completely, open the door and remove the tray, now insert the brew group and replace the tray.
