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

Pump not securely bolted to base, Uneven or loose mounting pad, Air in system causing cavitation, Imbalanced impeller

Safety first: Turn off the pump before tightening any hardware.

Secure mounting: Check that the AstralPool pump is firmly bolted to a solid, level base. Tighten mounting bolts and add rubber isolation pads if necessary.
Check for air and cavitation: Ensure proper priming and that there are no suction leaks. Cavitation can cause loud rattling and vibration.
Inspect impeller: If vibration persists, remove the wet end and inspect the impeller for broken vanes or heavy debris stuck on one side.
