This procedure assumes that the DW water connection and drain are flexible. Remove Phillips head screws (2) mounting top front of DW to underside of counter. Grasp door and gently coax DW outwards approximately 1 foot. WEAR SAFETY GOGGLES. On RHS check lower end of door spring and note in which notch the spring sits. On RHS, grasp white plastic connector ("hinge bushing", with spring looped around one end), stretch the spring while carefully lifting other end of connector up, out of slot in door hinge lever. Pry door hinge lever 1/8" away from DW body while sliding friction sleeve over its end. Work friction sleeve past hinge hook, past wider section, into narrower slot (about 2" from end of hinge hook). Raise door to closed position. Insert and hold lower (90 degree) end of spring into the same notch that it was originally in (mine was in the 5th from the front). Loop the door end of the spring into one end of the white plastic hinge bushing, then insert the other end of the bushing into the door hinge lever's hook while stretching the spring. It does not require much strength. CAUTION: If the lower end of the spring is not properly inserted and held in the notch, it can pop out and possibly injure you! Repeat for the LHS. Push the DW back in place, and reinstall the two mounting screws.
