Hello, I have a keys backyard tub, it has been working fine for years until i drained it to change the water. I flipped the breaker back on and it is not working. I can hear a "click" from the control panel when the breaker is switched back on but nothing will run whatsoever. The breakers are not bad and the fuses are not blown in the control panel. Can someone please give me some advice to what it may be or what else i can try to get it going? Thank you in advance.
