Common symptoms this part fixes

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

  • HH fault code (high heat error) displayed on topside panel
  • OH fault code (overheat error) displayed on topside panel
  • Spa water not heating or taking excessively long to reach set temperature
  • Heater element burned out or visibly corroded
  • Intermittent heating — spa heats briefly then faults out
  • Spa control board shows heater circuit open or heater failure

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

Before you buy — quick checklist

  • Confirm your spa control system is M1, M2, or M3 series — check the label on your control pack or circuit board
  • Verify your existing heater is rated for 230V before ordering — do not install on a 120V system
  • Check whether your fault codes (HH or OH) are genuinely heater-related and not caused by a failed high-limit sensor, pressure switch, or flow switch, as those components would need separate replacement
  • Inspect the existing heater manifold unions and plumbing connections before ordering to confirm this assembly's inlet/outlet configuration matches your installation
  • If your spa is repeatedly throwing OH or HH codes, investigate root cause (low flow, dirty filter, blocked circulation) before replacing the heater — a new element will fault again if the underlying issue is not resolved

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