I need help! Bought a brand new Intex Krystal clear sand filter. Set everything up per instructions. Let run for 3 hours it was fine. Next day went to turn it on and it didn't work at all. Came home from work and the red dot was there as if in power safe mode turned on and worked for like 3 minutes and Darn off. Can't get anymore power in it now. Won't turn on at all. All of the power cords are getting power and it's not tripping anything. I just need it to work already. Please help what can I do or what can it be. It's three days old
