We'd like to assist with your dishwasher's upper rack falling off of the rail. It's extremely important not to overload the upper rack with dishes. Overloaded racks will prevent the rack from gliding smoothly and cause the rack to come off the rail. Our dishwasher upper racks are life-tested to handle a 30 lb. load; Lower racks are tested to handle a 50 lb. load. If the issue continues, we recommend scheduling service with our Bodewell team by calling 1-833-426-3393 or online here: https://www.geappliances.com/ge/service-and-support/service.htm.
