Front control dishwashers have the controls displayed on the front, whereas in top control dishwashers, they are on the top of the door and cannot be seen when the door is closed. Front control is generally cheaper, but the open display of controls can be an issue, especially if toddlers are in the house. Top control models, on the other hand, are pricier but offer a clean elevated look. Within 24 In. Built-In Dishwashers, we carry 268 top control models. Check out the best-selling product, the 24 in.
