3rd Level Wash Spinner

I have a Whirlpool Quiet Partner III. With each cycle, I find a small spinner in the tray that has fallen out from the top of the unit. I put it back in and it stays in place…until the next use. I’m not sure if I just need to order the spinner itself (whirlpool part 8557720) or an assembly or whatever holds it in place in the top of the unit. I’ve found the follow, which appears to be the spinner and some mounting bracket. Is this what I need? Thanks a bunch!

What is the complete model number of the dishwasher?

Whirlpool Quiet Partner III, Model GU2400XTPS1.

You have to remove the upper dish rack and the top part of the feed tube (#1 on the [B]diagram[/B]). The spinner should be attached to the feed tube using a pin included in the kit.
