The Seth Man

I have read through everything online, and done every step possible to try and figure out the problem maybe you guys can help me, my spa stopped heating recently and I cleaned the filters and checked the heating element. it was covered in scale build up and had rust on it, also the breaker was tripping from time to time and in my experience that usually means it needs a new heater element. I noticed before replacing the heater element that there was no power going to the heating element. I thought it was safe guarding the spa till it got a heating element that could hold the power and not pop the breaker. replaced the element and there is still no power to the heating element and the tub will not heat up. it's not popping the breaker anymore. but there is no power going to the heating element. as far as i can tell all the fuses are fine. I can hear the relay working but no power to the element. there are no codes popping up. thanks
