Possible Causes

Very low water temperature at startup, Sensor reading below safe heating threshold, Recently winterized spa refilled with cold water

How to Fix / Troubleshooting

Safety first: Ensure all plumbing is thawed before operating the spa.

  • Gradual warm-up: Allow the Everlast heater and pumps to run as programmed. COd should clear as water temperature rises.
  • Insulate: Keep the Everlast cover closed and consider adding a floating thermal blanket to speed heating.
  • Sensor check: If COd persists in moderate temperatures, test the temperature sensor and replace if it reads abnormally low.
