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 displayed on topside panel
  • OH (overheat) error code that won't clear
  • Spa water not heating or heating very slowly
  • Heater element failure — no heat output despite pump running
  • Nuisance tripping of high limit sensor due to failed heater assembly

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

Before you buy — quick checklist

  • Confirm your spa runs a Balboa BP7 control system — check the control box label or topside controller
  • Verify your spa is wired for 230V before ordering this heater
  • Inspect existing heater unions and plumbing connections for damage or corrosion before reinstalling
  • Check whether your HH or OH error is caused by the heater element vs. a faulty high limit sensor — replacing the wrong part wastes time and money
  • Have your spa's serial number and control board model ready in case you need to confirm fitment with our team

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