Common symptoms this part fixes

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

  • Spa water not heating
  • Heater error code on control panel (HH or OH fault)
  • Spa heats intermittently or inconsistently
  • Heater element burned out or visibly corroded
  • Spa trips GFCI breaker due to failed heater element
  • Spa takes excessively long to reach set temperature

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your spa runs a Gecko SSPA control system — this heater is designed specifically for that platform
  • Verify your spa is wired for 230V before ordering
  • Check your existing heater tube dimensions — this unit is 2" x 15", measure before purchase
  • Inspect heater unions and union O-rings — replace O-rings at the same time to prevent leaks after reinstall
  • Confirm the cause of failure before replacing — a persistent OH fault may indicate a flow issue, not just a bad heater
  • Check that your circulation pump and filter are functioning properly; a failed heater from restricted flow will fail again if the root cause isn't fixed

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