I don't think there is a clog. I just ran a cycle, and there was only the normal two teaspoon's worth in the bleach part of the tray this time. Two loads in a row left the tray full of water, a third load worked normally. A fourth load had the dispenser full of water at the end, and now the fifth load worked normally. What do you make of that?
Well, I'll keep watching it over the next week and will see what happens.
