Yes, you can use hot water in a dishwasher along with soap or detergent. In fact, hot water is typically recommended for optimal cleaning performance in dishwashers. Hot water helps to dissolve and remove food particles, grease, and stains more effectively, resulting in cleaner and more sanitized dishes.
Most dishwashers are equipped with a heating element or a built-in water heater that heats the water to high temperatures during the wash cycle. The exact temperature can vary depending on the dishwasher model, but it is typically around 120-150 degrees Fahrenheit (49-66 degrees Celsius). This hot water, combined with the detergent, aids in breaking down and removing food residues from dishes, utensils, and other items.
It's important to follow the manufacturer's instructions and guidelines for your specific dishwasher model and detergent. Some dishwasher detergents are designed to work best with hot water, while others are formulated to be effective with cooler water temperatures. Using the appropriate amount of detergent and setting the dishwasher to the recommended temperature will help ensure optimal cleaning results.
