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 not clearing after reset
  • Spa water not heating or heating too slowly
  • Heater cycling off prematurely under low flow conditions
  • Spa control system reporting heater fault or open circuit

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

Before you buy — quick checklist

  • Confirm your spa runs on 230V — do not install on a 115V system
  • Verify your existing heater is rated 5.5kW before ordering — mismatched wattage can cause control board issues
  • Check that your spa is a Sundance model with a low flow heater configuration — not all Sundance spas use this heater type
  • Inspect flow switch and circulation pump before replacing heater — HH and OH codes are sometimes caused by a flow fault, not a failed element
  • Confirm the SKU or part number on your existing heater assembly before ordering

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