Possible Causes
How to Fix / Troubleshooting
Safety first: Repeated GFCI tripping indicates a potentially dangerous fault. Do not bypass or replace the GFCI with a non-GFCI breaker. Turn off power and leave it off until the fault is found.
- Inspect for moisture: Open the equipment bay and control pack housing to look for water or condensation. Dry thoroughly and correct any leaks.
- Isolate components (technician recommended): Disconnect heater, then pumps, then other accessories one at a time and restore power to see when the GFCI stops tripping. The last reconnected component is likely faulty.
- Test heater to ground: With power OFF, use a megohmmeter or insulation tester to check for leakage from heater terminals to ground.
Because of shock risk, this diagnosis is best performed by a qualified spa technician or electrician.
