Freeflow Spas Worn Circulation Pump Bearings or Debris in Impeller

Circulation pump is noisy, rattling, or grinding during operation.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Aging circulation pump, Scale or debris in pump, Running pump dry after low water level, Misalignment or vibration against cabinet

Safety first: Turn off power before inspecting the pump.

1. Check for air: Bleed the circulation pump union to ensure it is fully flooded; air can cause noise.
2. Inspect mounting: Confirm the pump is securely mounted to its base and not vibrating against the cabinet or plumbing.
3. Flush system: Run the spa with jets on to help flush small debris through the system.

Persistent grinding or rattling usually means the circulation pump is near end-of-life and should be replaced with a Freeflow-compatible unit.
