What is the normal operating temperature of a dishwasher wash cycle?

• A. around 50°C
• B. around 60°C
• C. around 70°C
• D. around 80°C

Answer: (B)

The wash cycle in a dishwasher is normally run around 60°C. This temperature provides an effective balance: detergent can break down fats and soils, and the wash helps reduce microbial load without placing excessive stress on equipment or wasting energy. Sanitizing is then achieved in the final rinse, which is hotter—typically about 82°C or higher for a short dwell time. Temperatures around 50°C are generally not enough for proper cleaning, while 70–80°C would use more energy without needed benefits for the normal wash stage.
