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

Safety First: Turn OFF power before inspecting under the sink or inside the chamber.

• Step 1 – Check for loose mount: Under the sink, verify that the mounting ring is tight and the unit is firmly attached to the sink flange.
• Step 2 – Inspect impellers: Remove the splash guard and inspect the impeller lugs. They should pivot but not wobble excessively. If they appear heavily worn or loose, grinding efficiency and noise will worsen.
• Step 3 – Verify insulation: Some Kraus models include sound insulation around the housing. Check that any external sound shell is intact and not missing.
• Step 4 – Evaluate age: If the disposal is older and internal wear is evident, replacement is the practical solution to restore quiet operation.
