Dynasty Spas Pump Bearing or Wet End Failure

Spa makes loud grinding or squealing noises from the pump area when jets are on.

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 motor bearings on Dynasty jet pump, Damaged impeller rubbing housing, Cavitation from low water or air leaks

Safety first: Turn off power before inspecting the pump.

Check water level and valves: Ensure proper water level and that all valves are open to prevent cavitation.
Inspect pump: Remove the equipment bay panel and listen closely to identify which pump is noisy.
Check for leaks: Look for water leaking onto the motor, which can damage bearings.
Replace pump or wet end: If noise persists and bearings are failing, replace the pump motor or complete pump assembly with a Dynasty-compatible unit.
