Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

Before you buy — quick checklist

  • Confirm your spa runs on a 230V electrical system — this heater is not compatible with 120V setups
  • Verify your spa uses a Gecko SSPA control system or is an LA Spa model that specifies this assembly
  • Check your existing heater's wattage rating — this is a 4.0KW unit and must match your system's heater specification
  • Inspect the union fittings on your existing heater before ordering to confirm plumbing compatibility
  • Note the error codes your spa is displaying — HH and OH codes point to heater or temperature sensor issues that this part addresses

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