Common symptoms this part fixes

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

  • No heat — spa water stays cold
  • Spa displays NH (No Heat) error code
  • Spa displays OH (Overheat) error code
  • Heater element failure causing control system fault
  • Intermittent heating — spa loses temperature unexpectedly
  • Corrosion or scale buildup on existing heater element causing failure

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
  • Match the OEM part number C2550-0103TT on your existing heater before ordering
  • Verify this is a flow-through heater configuration, not a pressure-switch or bypass-style assembly
  • Check for any active water leaks at the heater manifold before installing — address leaks first
  • Confirm your existing titanium element failed rather than a relay or high-limit sensor — misdiagnosing the fault is common
  • Have a licensed electrician handle the 230V wiring connections if you are not certified to work on high-voltage spa equipment

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