Rust in a washing machine is typically caused by a combination of moisture, metal, and oxygen. Over time, the drum's metal surfaces corrodes, leading to rust formation. This can be accelerated by hard water, which contains high levels of minerals like calcium and magnesium, or aggressive detergents.
