We've been testing dishwashers for years now, and hundreds of models have faced our gauntlet of strict lab tests. But a dishwasher with a window? It's practically unheard of. The KitchenAid KDTM804ESS (MSRP $2,049) is one such model, and that fancy window isn't the only stand-out feature included. This new, top-of-the-line dishwasher has a ton of premium features, including a third rack, an advanced food particle filtration system, and a ton of adjustable parts.
