I can move the wash arm to any position in the dishwasher, shut the door, letting the cycle continue to wash and when I open the door, it will always be perpendicular to the door. Once it gets there, it will not move anymore, but moves manually. Also I don’t think there is very much water coming out of it (not enough to spray). So i tried a solution of CLR for cleaning out the dishwasher. It didnt resolve the problem, so I purchased and installed another middle arm and middle spray arm seal. It still does not work.
Any other suggestions you have to fix this problem would be most appreciated.
