Possible Causes

Air in jet pump plumbing, Recently refilled spa not properly bled, Jet pump not starting, Blocked suction or closed slice valves

How to Fix / Troubleshooting

Safety first: Ensure all slice valves are open before running pumps.

  • Prime pumps: After a refill, run each jet pump on low and high speed. If a pump hums but does not move water, turn power off and loosen the pump union slightly to release air, then retighten and retry.
  • Check suctions: Make sure suction covers are not blocked by debris or ice.
  • Cycle power: Once strong flow is established, power-cycle the spa to exit priming mode.

If a pump will not start or repeatedly loses prime, the pump or its capacitor may need replacement.
