Possible Causes

Water inside electrical compartment, Shorted heater element to ground, Damaged power cord, Internal wiring insulation failure

How to Fix / Troubleshooting

Safety first: Repeated tripping indicates a potentially dangerous fault. Do not repeatedly reset breakers or GFCI without finding the cause.

  • Inspect externally: Check that the control unit is dry and not sitting in water. Inspect the power cord for visible damage.
  • Try another outlet: If safe and permitted, test on a different properly grounded circuit to rule out house wiring issues.
  • Do not open sealed units: Internal shorts in the heater or pump require professional service.

Stop using the spa until it has been inspected and repaired by a qualified electrician or spa technician.
