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
  • DR or FLO error code on topside display
  • Heater element burned out or visibly failed
  • Spa water stays cold despite pump running normally
  • Inconsistent water temperature

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

Before you buy — quick checklist

  • Confirm your spa runs on 240V — do not install on a 120V system
  • Verify the DR or heating fault code is element-related, not a failed sensor or flow switch
  • Check your existing element's kW rating matches 5.5kW before ordering
  • Inspect the heater manifold for corrosion or cracking — a failed element can mask a damaged housing
  • Confirm this is an OEM Sundance part number match for your specific spa model year

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