The "spinner, 3rd level wash" kept falling off. Ordered new part, no instructions with it.
I had the same problem, the 3rd level spinner falling off. Without getting into my saga story, save yourself some $$$.
-You will need a screw & washer to replace the plastic thumbtack. The screw will have to be able to screw into the female part of the spinner; the washer will keep the screw from falling out of the hole in the flat hose on the ceiling of the dishwasher.
-If you look closely at the spinner(the part that keeps falling off), you will notice it comes apart. With a flat head screwdriver, separate the 2 parts. (there are 3 parts all together; Keep the round center piece sticking out of the top peice)
--Remove the top drawer of the dishwasher to give you some room to work
-Remove the screw on the "ceiling" of the dishwasher(it is located further back from where the spinner goes) to allow the flat pastic tube to come down low enough for you to get in behind it.(set that screw aside in a safe place; you will put it back later)
-Remove the pastic thumbtack from the hole in the flat plastic tube if it is there & replace with a washer and screw.
-Take the top 2 peices of the spinner, together as assembled & screw the screw into the female portion of the spinner.
-snap on the 3rd piece of the spinner
-replace the screw you took out earlier, securing the flat plastic tube.
-place top drawer
Voila, you are done!! You just saved yourself $20+
