Garbage disposal vibrates excessively and shakes the sink or countertop during operation

Safety First: Turn OFF the wall switch and breaker before inspecting the unit.

• Inspect for foreign objects: Shine a flashlight into the disposal and remove any large items or buildup on one side of the grinding plate using pliers.
• Check impeller movement: Gently move each impeller lug with a wooden spoon handle. They should swing freely. A stuck lug can cause imbalance.
• Verify mounting tightness: Under the sink, check that the Waste Maid mounting ring is fully locked and the three mounting tabs are engaged. Tighten the mounting screws evenly if present.
• Inspect rubber mount: Ensure the rubber mounting gasket between the sink flange and disposal is intact and seated properly. Replace if torn or deformed.
• Test with water: Restore power, run cold water, and briefly operate the disposal. If severe vibration persists, the grinding plate may be warped and the unit should be replaced.
