How to Fix / Troubleshooting

Safety: Do not repeatedly reset a tripping GFCI; this indicates a potentially dangerous fault. Turn off power and leave it off until the issue is identified.

  • Visual inspection: Open the equipment bay and look for obvious water leaks, burnt components, or melted wiring.
  • Isolate components: With power off, disconnect one major component at a time (heater, pumps, ozone) from the Villeroy & Boch control pack. Restore power and see if the breaker still trips. This helps identify the faulty component.
  • Dry moisture: If water is present in the control pack, dry it thoroughly and correct the source of the leak.

Ground faults and shorts should be diagnosed and repaired by a qualified electrician or spa technician.
