EDIT: WE FIGURED IT OUT!
This gasket looking bit came out of the dishwasher. Been scouring parts pages and see nothing like this for our model. Itβs a Kenmore 66515872000.
Itβs not the door seal, and there doesnβt appear to be anything missing where it might fit in the floor of the washer. It was a circle (broke while dish rack was being pulled out) and is 9 inches in diameter, 1/4 inch high and 1/8 inch thick.
Any ideas?
