Marie A Columbia , SC February 13, 2016 One of the rollers for the dishwasher upper rack cracked causing the upper rack to move with difficulty I found the diagrams for dishwasher parts on AppliancePartsPros.com and located the needed part. The video about how to replace the part was helpful. The part arrived in 3 days and I installed it the same day. Everything works well now.
