Aeg and Kwikot warranty short coming and poor product quality

I'm most disappointed in the warranty service for AEG appliances, handled Kwikot. An AEG 'stainless steel' dishwasher I purchased less than a year ago has started to show multiple spots of rust on the exterior and I was advised that 'staining' is no covered by the AEG warranty!? Total ******* product quality and warranty!!
