My stainless utensils have rust on them after being cleaned in the dishwasher.
Do not attempt service or replace parts of the appliance unless referred to in the owner's manual. Follow all safety precautions provided in the owner's manual.
Rust on dishes can form if the water supply has a high iron content. Although iron may not be visible in the water, it can leave yellow to brown stains on dishes or the dishwasher interior. Using the recommended amount of powder dishwasher detergent will help prevent staining. Powder detergents hold minerals in suspension better than liquids and gels. To remove rust stains from the dishes, use a mild abrasive cleaner that contains a rust remover.  
 
Not all tableware labeled stainless is pure stainless. Some are combinations of stainless and other metals which may rust. These items should be washed by hand and dried immediately.  
 
Exposed metal on dishwasher racks may rust and leave deposits on dishes. Racks should be replaced if the metal is exposed.
