Solar powered Electric water pump, float switch problems? - solar powered water pump

I have a solar system that works well, which fills a tank of 6000 liters. The tank has a float switch in it. A few days ago I realized the tank was empty, and can not pump. It appears that the fuses are good, and I pulled the float switch with a stick trying to get them. If anone has other ideas about how to solve this problem?
