Steve for Model Number PDW788ON20SS MY GE dishwasher lower spray arm stop spinning and when I inspected I realized that a circlular plastic bushing ring at the base of the assembly was cracked and thus not allowing the base of the spinning arm to seat onto the spot where the arm attaches to the dishwasher. When looking at the pictures for my model the arm looks different and the replacement part does not appear to be avialable. Please advise.
Answer Steve, the lower spray arm WD22X10047 is the original part used on your model. This is installed with the hub nut WD12X10061 onto the main conduit WD12X10057. Thanks. Read More... Answered by AppliancePartsPros.com | Monday, October 15, 2012
