Mine has no problem. I just take the pump out of my jug and stickit the other one. Even if it is air bound it will eventually get going. Again, same with me, a shake will take care of it. My hose and cord must be straighter or drops down different because mine stands straight up all the time. One the out side of my jug there is a bend in the cord hose so perhaps it holds it there better because of that. OK...then you have a problem. Look is your owners manual. That is what the RED light on the panel is for. The controller is programed so that if the pump runs for 5 minutes and it fails to reach proper sensor level, then an alarm will sound, the RED LED will come on and the pump will shut off. For this very reason, a dry make up bottle. To reset you just have to unplug it and plug it back it, the RED led will clear, the pump will start you will reach level and it will work like normal. .....I had something go wrong with mine. The red light come on, but there was water. So I had to send it to Texas. They fixed it free and it has worked perfect since. Even with that, I would not think twice about buying another one. Great unit and great service.
