Disposal is extremely loud compared to when it was new, with a harsh grinding sound even when empty.

Safety first: Turn OFF power before inspecting.

• Check for debris: First rule out foreign objects by inspecting and cleaning the chamber with tongs.
• Inspect metal surfaces: With a flashlight, look for heavy pitting, rust, or missing sections of the shredder ring inside the American Standard disposal.
• Listen during brief run: Restore power, run water, and operate the unit for a few seconds. If the harsh noise persists even with no load, internal wear is likely.
• Plan replacement: Worn grinding components are not replaceable individually. Consider replacing the disposal, especially if it is older or heavily corroded.
