Common symptoms this part fixes

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

  • Spa not heating or holding temperature
  • Heater error code on IN.YJ control panel
  • OH (overheat) fault that won't clear after reset
  • HH (high heat) error displayed on topside controller
  • Water temperature dropping despite thermostat calling for heat
  • Visible corrosion or calcification on existing heating element

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

Before you buy — quick checklist

  • Confirm your spa uses a Gecko IN.YJ control system — check the topside controller or control box label
  • Verify your existing heater is rated 4kW at 240V before ordering
  • Check whether your spa is wired for 240V service at the breaker panel
  • Inspect the heater manifold union size and thread type before removal to ensure the replacement will mate correctly
  • Note any active fault codes on your controller — some OH/HH errors are caused by sensors or flow issues, not the heater element itself

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