How to Fix / Troubleshooting

Safety first: Turn off power immediately if you smell burning. Do not continue to operate the spa.

  • Visual inspection: After allowing components to cool, open the equipment bay and look for discolored, melted, or burnt wiring and connectors.
  • Check heater terminals: Inspect the heater connections on the control pack for signs of overheating.
