Yes, you can run a full load of dishes through the dishwasher using just plain water and the heated dry setting on high heat. However, it's important to note that using detergent and rinse aid is generally recommended for optimal cleaning and drying performance.
Detergent is specifically designed to help break down and remove food particles, grease, and other residues from dishes. Without detergent, the cleaning effectiveness may be compromised, and you may not achieve the desired level of cleanliness.
Rinse aid, on the other hand, helps to reduce water spots and enhance the drying process by allowing water to sheet off dishes more easily. Without rinse aid, you may experience less effective drying, resulting in water droplets or streaks on your dishes.
While using plain water and the heated dry setting can still provide some level of cleaning and drying, it's likely that the results will be less satisfactory compared to using detergent and rinse aid as recommended by the dishwasher manufacturer. If you're out of detergent or rinse aid, it's generally best to wait until you can replenish them before running a full load in the dishwasher.
