How to Fix / Troubleshooting
Safety first: This involves live electrical circuits. If you are not experienced, contact a licensed spa technician or electrician.
- Visual inspection: With power off, inspect the control pack, pumps, and wiring for signs of water, burn marks, or melted insulation.
- Isolate components: Disconnect one component at a time (heater, pumps, blower, ozonator) and attempt to reset the breaker. The component that causes the trip when reconnected is likely faulty.
- Test heater to ground: Measure resistance from each heater terminal to ground. Any continuity indicates a ground fault; replace the heater.
- Dry out moisture: If water intrusion is found, correct the leak source and allow components to dry thoroughly before retesting.
