Mice have come through (!!) the vent on the left side of the tub! It is now all chewed up and won't stay on.
It is a round vent that fits on the left wall; not a float of any kind.
I cannot find this part on any of the diagrams for this model.
ANSWER Betty, Based on the post information, the mice have damaged the air/water inlet assembly. The best guess will be you'll need to repalce :
99002948, Cover, 99002646 Seal, 99002645 Air/Water Inlet, 99002852 Inlet Hose. You will also need to remove the dishwasher from the cabinet to access, check and replace these parts.
