What is the temperature of the dishwasher first rinse cycle?

• A. 150-165 degrees F
• B. 165-180 degrees F
• C. 180-190 degrees F
• D. 200-210 degrees F

Answer: (B)

High-temperature sanitation in healthcare dishwashing relies on reaching a hot enough rinse to kill germs on dishes. The first rinse cycle is designed to start this sanitizing process, so it should be hot enough to reduce microbial load but not so hot as to cause unnecessary strain on equipment or safety concerns. The 165–180°F range hits that sweet spot: it’s hot enough to achieve effective sanitation with an adequate dwell time, aligning with common hospital and food-service sanitation guidance. Temperatures below this range may not reliably sanitize, while temperatures higher than this are unnecessary for the first rinse and could risk wear or injury. So, the best fit for the first rinse cycle temperature is 165–180°F.
