Final answer:
For single-temp / stationary-rack dishwashing machines, the water must be at least 180°F (82°C) to effectively sanitize dishes and utensils.
Step-by-step explanation:
These machines typically use hot water in combination with detergent and rinse aid to clean and sanitize the items. The high temperature of the water helps to kill bacteria, viruses, and other microorganisms that may be present on the dishes.
