Yo remove the back you need to undo 10 screw bolts 2 of theese have an unusual head theese two are at the back of the lid. When you remove those two the lid slides back and can be removed, There are 4 more screws on the exterior of the machine two on the bottom of the back and two at the side. The two at the side are in the midle of the machine and are hidden by hole plugs, these can be removed by inserting a nail or similar into them. you then need to remove 4 more screws in the midle of the interior top of the machine when you see them you will know them, Once theese are removed tou will have to deal with the piece that holds the pipes in place there is an insert on either side squeese the two pins together and lift uo the back of the machine will now slide off. Good luck hope you get there
