I think I got too aggressive in disassembling my vacuum to clean the bin & filter. Now I can’t remember where two of the parts go. Is there an exploded diagram of our vacuum available?

The two parts are what looks to be a rubber gasket and a plastic ring. The gasket looks like it goes on the motor providing the seal around the base of the bin. But I cannot figure out where the plastic ring goes. I’ve tried putting the ring above and below the gasket, and I’ve flipped it over in both places, but to no avail. The plastic ring prevents the bin from snapping into place. I’m obviously missing something.

Thanks!
