Common symptoms this part fixes

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

  • Spa not heating or heating very slowly
  • OH (overheat) fault code on control panel
  • HH (heater high limit) fault code displayed
  • Heater element burned out or failed open circuit
  • Spa water temperature dropping and not recovering
  • Control panel showing heater-related error codes

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

Before you buy — quick checklist

  • Confirm your spa's heater is rated 5.5kW at 230-240V — check the label on your existing heater or your spa's service manual
  • Verify your existing heater uses 3/4 inch slip plumbing connections before ordering
  • Confirm this is a low flow heater application — not all Sundance systems use the low flow configuration
  • Check your control system is compatible with a Smart heater assembly
  • Inspect your high limit sensor and flow switch before replacing the heater — a faulty sensor can cause nuisance trips that mimic heater failure
  • Have your spa's model number and serial number on hand to cross-reference with Sundance's fitment records if you are unsure

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

Install difficulty: Hard — Technician recommendedTypically 60-120 minutes
