Possible Causes

Partially scaled heater element reducing output, Poor insulation or damaged Lifesmart spa cover, Circulation pump not running continuously, Incorrect voltage supply (wired for 120V instead of 240V where applicable)

How to Fix / Troubleshooting

Safety first: Turn off power before inspecting electrical connections.

  • Check cover condition: Inspect the Lifesmart spa cover for waterlogging, tears, or poor seal. Replace if heavy or damaged.
  • Verify voltage: Have a qualified electrician confirm that the spa is wired for the correct voltage (many Lifesmart models can be 120V plug-and-play or converted to 240V).
  • Inspect heater for scale: Look for white mineral buildup on heater unions and plumbing. Use a spa-safe descaler if needed.
  • Confirm circulation: Ensure the circulation pump runs as programmed and that water is always moving through the heater when heating is called for.
