Hi, I have a 2004ish used calspa. The gfci tripped and keeps tripping. I cleaned the wire terminals and installed a new gfci breaker, unplugged the spa pack inputs one by one and it still tripped. So I opened the spa pack and removed the heater leads from the terminals and the gfci does NOT trip now and the motors fired up. Do I have a bad heating element that shorted out? What caused this? Where do I take it from here?
Much appreciated!!
