Common symptoms this part fixes

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

  • Spa not heating or holding temperature
  • HH (high heat) error code on control panel
  • OH (overheat) fault triggering repeatedly
  • Heater element failure or burnout
  • Spa water stays cold despite pump running normally
  • Control system reporting heater fault or open sensor

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

Before you buy — quick checklist

  • Confirm your spa control system is a HydroQuip M7 or M7-compatible unit — check the control box label
  • Verify your spa runs on 230V supply, not 120V
  • Check whether your existing heater uses the same M7 frame/manifold configuration before ordering
  • Inspect pressure switch and high-limit sensor — a failed heater is sometimes caused by a faulty sensor, not the heater itself
  • Note whether your current heater has a pressure switch or flow switch integrated — match the configuration

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

Install difficulty: Medium — Some experience neededTypically 45–90 minutes
