Disposal vibrates excessively and causes the sink or countertop to shake during operation

Safety first: Turn off power at the switch and breaker before inspecting.

• Check for debris: Look into the chamber with a flashlight and remove any lodged items with tongs. Rotate the plate manually to ensure smooth movement.
• Verify mounting: Under the sink, confirm the Quick Lock® mounting ring is fully rotated to the locked position and that the disposal is firmly supported.
• Inspect discharge piping: Ensure the discharge elbow and trap are aligned without forcing the disposal sideways or downward.
• Test with water: Run a strong flow of cold water and operate the disposal. Mild vibration is normal; strong shaking indicates imbalance or damage.
• If vibration persists: The grind plate or impellers may be bent. Replace the disposal to correct the imbalance.
