Garbage disposal leaks from around the sink flange at the top of the unit.

Safety First: Turn OFF power and disconnect the disposal before removing mounting hardware.

Step-by-step:

• 1. Confirm leak location: Fill the sink with a few inches of water and observe under the sink. If water appears around the top of the KitchenAid disposal where it meets the sink, the flange seal is leaking.
• 2. Remove disposal: Support the unit from below, rotate the mounting ring counterclockwise to release the disposal from the sink flange, and set it aside.
• 3. Remove sink flange: From above, lift out the sink flange. Scrape away old plumber's putty or gasket material from the sink opening.
• 4. Re-seal flange: Roll a rope of fresh plumber's putty and apply it under the flange lip. Press the flange into the sink opening and reinstall the upper mounting hardware from below, tightening evenly.
• 5. Reinstall disposal: Reattach the KitchenAid disposal to the mounting ring, ensuring all three lugs lock securely. Reconnect plumbing and power, then test for leaks.

When to call a technician: If the sink itself is damaged or corroded around the drain opening, a professional may be needed to repair or replace the sink.
