I hate this thing. I tried to start it up once but it didn't have water in it. Then i put water in it and it was good, but out of the blue it stopped working. The water was still in it, there was nothing stuck, and everything is plugged in. I know this isn't a problem about electricity because my heater works just fine. How do I fix this? EDIT: the filter is not making any noise when i start it. When I didn't put water in the filter, it made a noise. But now it makes no noise at all. Nothing is moving. My stepdad notices the motor was really hot, but i can,t find anything that could be stuck.
