A good dishwasher typically has two racks. The top rack is designed for smaller and more delicate items such as glasses, cups, and smaller bowls. The bottom rack is meant for larger items like plates, pots, and pans.
The two-rack system allows for efficient loading and maximizes the dishwasher's capacity, making it easier to organize and clean different types of dishes. Some dishwashers also come with a third rack, commonly known as a "cutlery tray" or "cutlery basket," positioned at the top or bottom. This extra rack provides additional space for utensils, freeing up more room in the main racks for other items.
Having two racks in a dishwasher is a standard feature and should be sufficient for most household needs. However, the specific configuration and layout of the racks can vary depending on the dishwasher model and brand. Some dishwashers may offer adjustable racks or folding tines, providing more flexibility for accommodating larger or oddly shaped items.
