Common symptoms this part fixes

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

  • Spa not heating or slow to reach set temperature
  • HH error code displayed on topside control
  • OH (overheat) error code triggered repeatedly
  • Heater element burned out or failed continuity test
  • Spa control shows heater fault
  • Water temperature dropping below set point with pump running

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

Before you buy — quick checklist

  • Confirm your spa control system is a HydroQuip BP7 or TP700 series — this heater is not universal
  • Verify your system is rated for a low flow heater configuration before ordering
  • Check the wattage and voltage ratings on your existing heater label before replacement
  • Test your high-limit sensor and pressure switch first — HH and OH codes are not always caused by a failed heater element
  • Inspect the heater tube for corrosion or scale buildup that may have caused the original failure

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