Important Tips for GE Models

GE notes rust stains may originate from objects placed inside and that cosmetic rust on stainless screws or heating elements is surface iron, not part deterioration; citric acid treatment can remove stains. (GE Appliances

Part: Internal tub surfaces, racks

Mineral deposits or iron in water supply causing rust formation

How to Identify: Rust or brown staining that appears broadly on interior surfaces that is not localized to rack damage; known hard water area.
