I am trying to re-attach the upper spray arm to the bottom of the top rack and snapped the tabs off. How was I to do it properly?
Answer Heather, It's easier if you remove the rack assembly 3369903 from the dishwasher. Remove the track stops 300845 from the rails and slide the rack out and set it on it's side. You'll need to work from the bottom side of the rack, you can twist the assembly, to release the tabs from the rack rungs, or use a pair of pliers or flat blade screwdriver to carefully push in on the tabs to release them from the rack rungs. But you do have to be careful.
How to reconnect upper arm (3) to the tower (5).
The upper spray arm does not attach to the tower. The tower comes up through the lower rack and it will shoot water up through the upper spray arm. If they were attached then the racks would not be able to come out.
