We have a 4 month old sub pump that runs occaisonaly as we live in a rainy area. It runs about 7-8 times a day, at least when I notice it running. But since 3 days agoo, it is not sensing that there is no water in it. It is constantly running, and there is steam coming from it. In order to get it to turn off, I have to poke the arm with a long stick. But then when it fills, and runs again, it stays on... What is the problem!!??
