Possible Causes

Age-related bearing wear, Water intrusion past mechanical seal, Corrosion on motor shaft, Misalignment between motor and wet end

How to Fix / Troubleshooting

Safety first: Turn off power before inspecting the pump.

Steps to evaluate noise:

  • Isolate source: Listen closely to determine if noise is from the motor body rather than the wet end or plumbing.
  • Check for seal leak: Look for rust or white scale at the junction between the Jacuzzi pump housing and motor flange, indicating seal leakage into the bearings.
  • Spin shaft: With power OFF and motor removed from the wet end, spin the shaft by hand. Roughness or play indicates bad bearings.
  • Plan replacement: While bearings can sometimes be replaced, most residential repairs involve replacing the entire motor and mechanical seal.

Operating with noisy bearings can lead to sudden motor failure. Replace the motor assembly promptly.
