Darlyne When the upper rack falls off the roller on one side and won't go back on the rollers, is it necessary to unscrew the round things screwed into the side of the dishwasher?
Answer Darlyne, No, you would not need to remove the 5304507405 Roller, Tub. You will need to remove the two(2) front 5300809927 Dishrack Stop, roll the upper dishrack out of the 154597801 Rack Slide(s) and check and repair or replace the 154522902 Wheel & Bearing. Make sure the "clip" on the wheel bearing/ axle are snapped and locked in place on the wall tines on the side of the rack. Read More...
