About this heater

Common symptoms this part fixes

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

  • HH (high limit) error code on In.Xe control panel
  • OH (overheat) error code that won't clear
  • Spa not reaching or holding set temperature
  • Heater element failure — water not heating at all
  • Intermittent heating with no apparent cause
  • Control system repeatedly tripping on high-limit fault

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

Before you buy — quick checklist

  • Confirm your spa runs a Gecko In.Xe control system — this heater is not universal
  • Verify your spa is wired for 240V before ordering
  • Check that your existing heater is rated 4.0KW — do not substitute a different wattage without consulting your control system specs
  • Inspect the existing heater unions and plumbing connections before removal so you have the correct fittings on hand
  • Confirm the 5-output, 3-pump configuration matches your current In.Xe board setup
  • If your HH or OH code is recurring, also inspect the high-limit sensor and flow switch before assuming the heater element is the root cause

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