My Intex SF80110 pump isn't turning on. I have power to the pump but the display is showing a red period (power saving mode). The power button is hot to touch. I don't know if the pump could be overheated or what. It was running fine and then I shut it off to do a backwash and now I cant get it to turn on. I've tried unplugging it and covering it with something to give it time to cool down but it still won't start up. I get the power save mode slot but it seems to turn on if I cycle the power. This is the first time I haven't been able to get it to turn back on. How do I know if the pump thermal switch is tripped? Does it display the red period if it is?
