It is generally not recommended to run a load of dishes in the dishwasher without detergent. Dishwasher detergents are specifically formulated to break down grease, remove food particles, and provide effective cleaning. Without detergent, the cleaning performance of the dishwasher will be significantly compromised.
Detergents contain surfactants and enzymes that help remove food residues and stains from dishes. They also contain ingredients that help prevent redeposition of soil onto clean dishes during the wash cycle. Without detergent, the water alone may not be able to adequately clean the dishes, and you may end up with unsatisfactory results, such as leftover food particles or a film on the dishes.
Furthermore, dishwasher detergent helps sanitize and eliminate harmful bacteria, ensuring that your dishes are hygienically clean and safe to use. Without detergent, the dishwasher may not be able to provide the necessary sanitization.
If you find yourself without dishwasher detergent, it's generally better to wait until you can obtain some before running a load. Using alternative cleaning agents not specifically designed for dishwashers, such as regular dish soap or laundry detergent, can cause excessive foaming, potentially damage the dishwasher, or leave behind residue on your dishes.
In summary, using dishwasher detergent is essential for achieving effective cleaning, sanitization, and optimal performance of your dishwasher. It is not recommended to run a load of dishes without detergent.
