Lower Spray Arm WD22X135

I first assumed that the leak was from the door gaskets getting old (unit is near 25 years old). Therefore I replaced the door gasket and two bottom corner gaskets first (no tools needed, took about 15 minutes). All gaskets remove easily and the new door gasket "snaps" back into a groove. Pay attention to how the bottom corners of the door gasket are installed. The bottom corner gaskets simply fit back into their openings. But, leak continued. Further investigation revealed the lower offset spray arm had worn out and had a big hole in the bottom of it, which was spraying water up through the bottom lip of the door. It took about 15 minutes to replace the arm, by simply unscrewing the spray tower (reversed threads - using only my hands). Problem solved, unit cleans much better. I hope to use it a few more years until a major kitchen remodel fits my budget.

Removed old lower spray arm, and replaced it with the new one.
