Canadian Spa Company Failing circulation pump

High-pitched whining or buzzing from circulation pump; water flow reduced.

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

Worn bearings, Scale buildup in impeller, Air lock, Electrical winding failure

Safety: Turn off power at the GFCI before working on the pump.

Bleed air: Loosen the circulation pump union to release trapped air, then retighten.
Clean filters: Ensure filters are clean to reduce strain on the circulation pump.
Inspect pump: Check for leaks or overheating. If the pump is very hot to the touch (when previously running), it may be failing.
Replace pump: If noise and poor flow persist, replace the circulation pump with a Canadian Spa Company-compatible model.
