Garbage disposal is extremely loud compared to when it was new, even with no foreign objects present.

Safety first: Turn OFF power before inspecting. Do not operate a unit that sounds like metal scraping or grinding internally.

• Step 1 – Rule out foreign objects: Carefully inspect the chamber with a flashlight and remove any debris with tongs.
• Step 2 – Check mounting and insulation: Ensure the mounting assembly is tight and the sound insulation (if equipped) is intact.
• Step 3 – Listen to motor: Briefly run the unit with water. A loud, rough, or growling sound often indicates worn bearings.
• Step 4 – Replace unit: Internal bearing wear is not repairable on Waste King disposals. Replace the disposal with a new, quiet model.
