George I am not blaming anyone for anything. The fact is for whatever reason it doesn't work properly. Mine is the larger version of yours and maybe that makes a difference. When it comes on it sucks too much food in too quick and jams the motor. I am out of things to try to get it to work. I have spent thousands of dollars on fish and building the pond. Paying another five hundred dollars after trying to get it to work for two years for me is worth it due to my lack of time. I have tried smaller pellets and they get sucked in too fast larger pellets just jam right away. Putting only one bag of pellets in at a time seems to help as does keeping the battery totally charged. I am open to any suggestions short of throwing it in the lake for structure.lol!
