Yesterday it was time to look at the rinse aid dispenser on my whirpool dishwasher. It has been leaking for months now. Since the dispenser was empty i figured it was a good time to see what could be done. I took the plug out for filling and went to home depo and picked up a box of #18 O rings. 10 in a package for $1.29. Came home remove the old O ring replace with one of the new ones and no more leaks. It seals real nice and how it goes back into the door is snug. No more leaks.
