Margie for Model Number PDW8280N00SS It appears from your diagram that part 450 only comes with with the center part (venturi?) and arm attached. I think I need to replace the center part - not the arm. I am OK with buying both if I have to. But . . I have tried to remove the center part and I can't. I saw a video where it turned counter clockwise and screwed out. Then I saw one of your repair posts where you said it didn't need to unscrew, that it just lifted out. I can't get the dang thing out either way. Can you help me out. I twisted the part (very, very difficult) about 10 times counterclockwise and it never showed any signs of coming lose. I think I must have broken something. I was trying to fix a drainage problem. I fixed that but now I am not getting enough pressure to rotate the 2 upper arms, hence dishes on top rack are not getting clean. I am female and old by the way. But I think I should be able to do this unless I have to completely remove the dishwasher and turn it over.
Answer Hello Margie. For this model you will need to order the conduit assembly to repair the issue your having with your unit. Read More... Answered by AppliancePartsPros.com | Friday, March 4, 2016
