What is the maximum water temperature allowed for dishwashers?

The maximum water temperature allowed for dishwashers is set at 180 degrees Fahrenheit. This temperature is particularly important for ensuring that dishes and utensils are effectively sanitized. At this level of heat, the water can properly kill bacteria and other microorganisms that may be present on dishes, thus meeting health and safety standards.

In commercial dishwashing processes, using water at 180 degrees Fahrenheit is critical for achieving the desired cleanliness and sanitation levels. Many health codes and plumbing regulations specify this temperature to ensure compliance with public health standards, which aim to minimize the risk of foodborne illnesses and ensure that dishes are not just cleaned but properly sanitized.

Other temperature options, while they may be sufficient for cleaning, do not meet the specific sanitization requirements set forth in plumbing codes and guidelines for commercial dishwashing operations, making them inadequate compared to the specified maximum of 180 degrees Fahrenheit.
