Common symptoms this part fixes

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

  • Spa water won't heat or holds temperature
  • HH (High Heat) fault code on control panel
  • OH (Overheat) fault code triggered repeatedly
  • Heater element burned out or failed open circuit
  • Spa heats intermittently or takes much longer than normal
  • Visible corrosion or scaling damage on existing heater tube

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

Before you buy — quick checklist

  • Confirm your existing heater is rated 4.0KW at 230V — do not install a mismatched wattage or voltage heater
  • Verify this is a HydroQuip-controlled system — check your control box label for the HydroQuip brand identifier
  • Match the union inlet/outlet size and plumbing configuration to your existing heater before ordering
  • Check whether your current fault codes (HH or OH) are actually caused by the heater vs. a faulty hi-limit sensor or pressure switch — replacing the heater won't resolve sensor failures
  • Inspect your heater housing for signs of water damage or burned wiring on the harness side — address those before installing the new unit

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