Garbage disposal causes a loud bang or clunk when starting or stopping.

Safety first: Turn OFF power before adjusting the mounting assembly.

• Step 1 – Check mounting ring: Under the sink, inspect the mounting ring or 3-bolt assembly. Tighten evenly to remove play between the disposal and sink flange.
• Step 2 – Inspect rubber gasket: If the rubber mounting gasket is compressed or deteriorated, replace it with a compatible Waste King gasket.
• Step 3 – Align piping: Ensure the discharge elbow and drain pipes are not forcing the disposal to one side. Adjust as needed.
• Step 4 – Test operation: Restore power and test. If the bang persists and seems internal, bearing wear may be present.
• Step 5 – Replace if internal play: Internal rotor play is not repairable; replace the disposal.
