I found a piece of the spray arm ( part no. AP2039850) , the central plastic cylinder piece, which is tapered near the top, and which has a central hole at the top and 3 side holes near the top, loose in the dishwasher. The dishwasher no longer cleans the dishes. I would like to replace the spray arm and am ready to order the part, but I cannot figure out how I would remove the present one and install the new one. Does the part come with directions or can you supply me with some directions? I don’t see any set screw or other means to work with.
Thank you for your assistance!
