How to Fix / Troubleshooting
Safety first: Repeated breaker or GFCI trips indicate a potentially dangerous fault. Unplug the spa and do not continue to reset.
- Visual inspection: Look for signs of water leakage or burning around the heater housing on the pump/heater unit.
- Isolate heater: If you are qualified and the design allows, disconnect heater leads and test insulation resistance with a megohmmeter. Most users should skip this and proceed to replacement.
- Replace assembly: A heater short typically requires replacement of the heater element or entire pump/heater unit.
Warning: Do not bypass the GFCI or operate the spa with a known ground fault.
