I drained my tub on friday, cleaned it today and refilled. Turned power back on and ran both pumps on high for 30 minutes. The display was reading fine when I first turned on pumps but when I went back out after 30 minutes the power was still on but the display was blank. So i turned the power back off and on again and the display is back up again. Why did this happen? Can anyone tell me? Four months ago I drained and refilled, started it back up and it ran for about 20 minutes and then tripped the braker. I flipped the braker back on and it tripped again 15 minutes later. I reset it again and it was fine until today. Please help.
