I have a Sundance Hawthorne that is tripping the GFCI breaker as soon as the pumps turn on. During diagnosis, I discovered when pump 1 is disconnected, it does not trip. Disconnecting pump 2 has no effect. Also, when the pressure switch is disconnected, both pumps run, but provides FL1 error. I replaced the pressure switch with a new one, and the trip still occurs. Disconnecting the heater element does not affect the breaker trip. I just replaced that pump last year, so I'd hate to think it's the pump again.
During diagnosis, I have also (none of which helped):
- Performed the "air lock clear" procedure with a water hose.
- Checked electrical connections throughout for corrosion or obvious shorts/loose wiring.
- Checked breaker box for moisture.
- Disconnected the temperature sensor on heater assembly.
- Disconnected the spa light.
- Disconnected the ozonator.
Any help would be appreciated. I've had issues with the tub in the past here and there but have always managed to identify the culprit. Really frustrating.
