What temperature does a dishwasher wash cycle normally operate at?

• A. around 40°C
• B. around 60°C
• C. around 75°C
• D. around 90°C

Answer: (B)

The main point is that the wash part of a dishwasher uses hot water to clean and reduce germs, and a typical wash temperature is around 60°C. This temperature is hot enough to loosen grease and soils and to help reduce microbial contamination, but not so hot that it wastes energy or risks damage to dishes and plastics. At around 40°C the heat isn’t enough to clean effectively or kill many organisms, so soils stay and bacteria can persist. Temperatures like 75°C or 90°C are much hotter than necessary for a normal wash and would use more energy and could risk damage; they’re more likely to be seen in special sanitising stages or very hot final rinses, but not in the standard wash cycle. So, around 60°C is the typical, practical wash temperature.
