I have a 5017 that recently started acting up. When I plug in the power to the unit lights flash too low too high red at a steady pace then the power turns off completely. After unplugging and replugging to power the unit resets shows the green light for a few seconds starts filling and after about 10-15 seconds does the same flashing thing then off. I am convinced that the pump must work since for the 10 - 15 seconds it pumps water, therefore it must be the controller. Is there anything I can do to remedy this? Why did it start doing this? Is it toast? Any experience with this issue and/or fixes would be appreciated. Thank you.
