The gasket on the back of the upper spray arm was falling apart and no water was getting out to the wash arm. The Grommet at the back was melted away.
Replacing both of these items was easy, one scew and it was fixed, the grommet went in easy.
The upper delivery tube was all I needed, but it came in a kit so I replaced everything.
Now it works great again. The videos were a great help. Thanks
