Common symptoms this part fixes

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

  • Spa won't heat or holds temperature poorly
  • OH (overheat) fault code on spa pack display
  • HH (heater high-limit) fault code triggering repeatedly
  • Element visibly corroded, scaled, or physically failed
  • Spa water takes excessively long to reach set temperature
  • GFCI trips when heater activates

Before you buy — quick checklist

  • Confirm your existing element is the M7 double-bend configuration — M7 refers to the physical form factor and must match your heater tube housing
  • Verify your spa pack operates at 230V — do not install a 230V element on a 120V system
  • Confirm your system is rated for 4.5KW — check your spa pack label or control box documentation
  • Locate the existing element SKU or stamp before ordering to ensure an exact match
  • Inspect the heater manifold and tube housing for corrosion or cracking before installing a new element — a damaged housing will ruin a new element quickly
  • Check that your spa's circuit breaker and wiring are rated to handle the 4.5KW load

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