I want to change dishwasher color plate?

I have an Ultra Wash Kenmore dishwasher that is about 8 year old and is beige in color. The dishwasher sticks out like a sore thumb because all my appliances are black and white. I wanted to find a part to replace not just the outside frame of the dishwasher from beige to white. The problem is I don't have the tech manual for the washer and the only part number listed on the inside door are 3377825 and 2274666. I called Sears part center and they said they don't have enough information and would need to provide the model number which I don't know. Any advice how I can get the model number of the dishwasher, so I can ask Sears if they have a white color plate and outside frame?
