Kraus garbage disposal runs but produces a high-pitched squeal or screeching noise.

Safety First: Turn OFF the disposal before inspecting. Avoid running the unit for extended periods while it is squealing.

• Step 1 – Inspect chamber: Remove the splash guard and check for small metal fragments or debris lodged between the turntable and grind ring. Remove with pliers.
• Step 2 – Manual rotation: With power OFF, rotate the turntable using a wooden spoon handle. If it feels rough or binds at certain points, internal wear is likely.
• Step 3 – Short test: Run cold water and operate the disposal for a few seconds. If the squeal persists even when empty, the motor bearings or internal bushings are worn.
• Step 4 – Plan replacement: Bearing and rotor alignment issues are not field-serviceable on sealed Kraus disposals. Replace the unit to prevent complete seizure.
