Aquaterra 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

Aged pump bearings, Scale or debris in impeller, Cavitation from air in lines, Pump running dry previously

Safety first: Turn off power before touching the pump or plumbing.

Bleed air: Loosen the circulation pump union to release any trapped air, then retighten.
Listen after reset: Restore power and listen to the pump. If noise persists, the bearings or impeller are likely worn.
Check for leaks: Inspect around the pump shaft seal for water leaks, which often accompany bearing failure.

Noisy circulation pumps usually require replacement. Order a compatible Aquaterra circulation pump and have it installed by a technician.
