What temperature range does a dishwasher rinse cycle normally operate at?

• A. 60°C
• B. 25°C
• C. 82-88°C
• D. 100°C

Answer: (C)

The key idea is that the final rinse in a dishwasher is meant to sanitize the dishes by using very hot water. This high-temperature rinse is designed to kill surface bacteria and help dry the dishes quickly once the cycle finishes. The typical sanitizing rinse range is around 82–88°C, which is hot enough to provide effective sanitization in a short contact time. Temperatures like 60°C are more typical of the wash phase, not the rinse, and 25°C is far too low to sanitize. While some special systems may use different methods, 100°C is not the standard rinse temperature for a normal dishwasher.
