How do I, take the lower spray arm off and replace with a new one? How does it disassemble?
This spray arm just snaps into place so you will want to just grab ahold of it and pull up and it should release.
How do I disasemble spray arm Item Number: AP4453743 so that I can clean it?
Answer Hello Ken. There is no way of taking the spray arm apart to clean the inside of it. You can run water through the spray arm and clean out the holes in it that way.
