Before you buy — quick checklist

  • Confirm your spa runs a Gecko IN.YT-7 control system — check the label on the control box inside the equipment bay
  • Verify your spa operates on 115V or 230V to ensure this heater matches your electrical supply
  • Note whether the HH or OH fault code persists after a cool-down reset — if it does, the heater assembly is likely the cause
  • Inspect the existing heater for visible corrosion, burned terminals, or a failed pressure/flow sensor before ordering, as sensor faults can mimic heater failures
  • Check that you have a licensed electrician available — heater replacement on a 230V system requires proper electrical disconnection and reconnection

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
