People often put their plates and cups on the top rack of their dishwashers for a few reasons:
Space optimization: The top rack of the dishwasher typically has a more adjustable configuration, allowing for larger items like plates and cups to fit more easily. By placing these items on the top rack, they can maximize the available space and load more dishes in a single cycle.
Water distribution: The spray arms in dishwashers are usually positioned at the bottom and in the middle of the dishwasher. By placing plates and cups on the top rack, they are closer to the spray arms, ensuring better water distribution and thorough cleaning.
Protection from heat: Some delicate or fragile items, such as certain types of glassware or fine china, may be more susceptible to heat damage. Placing them on the top rack, further away from the heating element at the bottom, can help protect them from excessive heat exposure during the drying cycle.
Avoiding direct water pressure: Some people prefer to place delicate or lightweight items on the top rack to avoid the direct force of the water jets, which can be more intense on the bottom rack. This can help prevent potential breakage or damage caused by the force of the water hitting the dishes.
Utensil tray placement: Many dishwashers have a utensil tray or basket located on the bottom rack. Placing plates and cups on the top rack allows for easier access to the utensil tray and prevents them from obstructing its function.
It's important to note that different dishwashers may have slightly different designs and configurations, so it's a good idea to consult the user manual or follow the manufacturer's recommendations for optimal loading and placement of dishes in your specific dishwasher model.
