Whirlpool garbage disposal makes loud grinding or metal-on-metal noises during operation.

Safety first: Turn off the switch, unplug the disposal, and shut off the breaker. Do not reach into the disposal with your hand.

• Visual inspection: Shine a flashlight into the disposal and look for foreign objects.
• Remove debris: Use long-nose pliers or tongs to carefully remove any metal, glass, or hard objects.
• Check impeller movement: Rotate the impeller plate with a wooden spoon handle to ensure it moves freely and does not contact the shredder ring abnormally.
• Test operation: Restore power and run the disposal with water. If abnormal noise persists, the impeller or shredder ring may be damaged and the unit may need replacement.
