Mario L Gilbertsville , PA June 12, 2015 Both the upper and lower dish racks were rusting in spots where the plastic coating had worn off I replaced both racks. The upper rack took about 5 minutes longer than the bottom due to removal of the rotating spray arm which had to be installed on the new rack. Very easily done. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
