Replaced the vent and gasket with new ones. A word of warning. The electrical connections are different on the new one and wouldn't fit. I was able to use the old switch on the new one but also took the rubber boot off the new one to replace the old one. (A little tricky) If I didn't do this I would have had to wait on a new electric harness as well but already had the dishwasher apart. Tested and all seem to work fine.
