unscrew screws at rear to slide off the top cover. check if there is a seam running down each side panel. pop small round circular plastic covers at the bottom, should reveal fixing screws. when removed machine splits in two. manufacturers are now using torx type screws to try to keep people out of the machines. you may need to buy a set of torx screwdriver bits to get the screws removed.
