I had my ozone check valve leaking yesterday, so my wife turned off the breakers to the hot tub until I came home to fix it. Put in the new check valve and flipped the breakers back on the hot tub won't turn on. There is a click coming from the IQ 2020 control panel. Upon investigating I see the LIM light and the control unplugged light come on and the I hear the click and it shuts off. It continues to do that,both lights come on and click nothing and then repeats? Any ideas what I should be testing? Or do I need a new control panel? A few years ago I changed out the heater relay board and heating element. But never have had any issues with the hottub. Thanks for any advise.
