Pump is very noisy, with grinding or screeching sounds from the motor area.

Safety first: Turn off power at the breaker before touching the motor.

• Confirm source of noise: Remove the pump lid and run briefly to determine if noise is from the motor, not from cavitation or air in the pump.
• Check for leaks: Inspect the mechanical seal area between the pump housing and motor for water leaks that may have entered the motor.
• Assess bearing condition: With power off, spin the motor shaft by hand. Roughness, grinding, or side play indicates bad bearings.
• Repair or replace: Bearings can sometimes be replaced by a motor repair shop, but often the most practical solution is to replace the motor assembly with a compatible Hayward motor.
