Disposal unit is corroded on the outside with rust flakes and appears near end of life.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Chronic moisture under sink, Past leaks from sink flange or plumbing, Condensation on cold housing, Age-related wear of painted surfaces

Safety first: Turn OFF power before touching a heavily corroded unit.

Inspect for active leaks: Check sink flange, dishwasher inlet, and discharge connections for current leaks and repair as needed.
Assess structural integrity: If the American Standard disposal housing is flaking heavily or has holes, it should be replaced.
Plan replacement: Choose a new disposal with similar mounting to simplify installation. Use new mounting hardware and ensure the area under the sink is kept dry.
