How to Fix / Troubleshooting

Safety: Turn off power before loosening any unions.

  • Bleed pump: Locate the main jet pump in the QCA Spas equipment bay. Loosen the discharge union until air escapes and water begins to seep out, then retighten.
  • Use garden hose method: With power OFF, remove a jet in the spa and insert a garden hose into the jet body. Run water to push air back through the plumbing into the pump and out the skimmer.
  • Cycle pump: Restore power and cycle the pump on and off a few times to help purge remaining air.
