This part is an upper dishrack assembly for dishwashers. The purpose of this part is to hold dishes and cookware during the washing process. There are two dish racks per unit, and this particular dishrack goes on the top of the unit. The lower dishrack assembly is sold separately. Over time, the upper dishrack assembly may rust due to the coating breaking down and water corroding the metal. If this happens, the dishrack assembly will become brittle and less structurally sound and will need to be replaced. If the attached rails have broken and will not attach to the sides of the dishwasher and slide appropriately, this part may need to be replaced.This upper dishrack assembly is compatible with dishwashers that are manufactured by the GE and Whirlpool brands. This particular component is an OEM part that is sourced directly from the manufacturer and is sold individually.Part Number WD28X10410 (AP5780496) replaces WD28X10266, WD28X10326, WD28X10330, WD28X10409, 2935038, PS8690633, WD28X10130, WD28X10136, WD28X10144, WD28X10155, WD28X10156, WD28X10160, WD28X10172, WD28X10187, WD28X10188, WD28X10199, WD28X10222, WD28X10224, WD28X10225, WD28X10258, WD28X10262, WD28X10265, WD28X10272, WD28X10275, WD28X10325, WD28X10329.
