Query: Used once in my Scooba/Pump valves dead Coincidence?

Have enjoyed my Scooba and have always used the vinegar option. Had a bottle of this product, so I finally used it since I had a new puppy coming to the house. The next time I used my scooba it wouldn't emit water. Tried all the online suggestions and nada. Online they refer to the pump valves as the source of the no water problem. I don't know what the valves are made of, but I find this to be a very strange coincidence. Now I have a scooba which runs but doesn't emit any water.
