What temperature should dishwater ideally be?

The ideal temperature for a dishwasher to operate effectively is around 120 degrees Fahrenheit. This temperature helps to ensure that the water is hot enough to break down food particles and dissolve grease, leading to more effective cleaning. At this temperature, the heat also aids in sanitizing dishes by killing bacteria and other pathogens present on the surfaces.

A temperature lower than this may not effectively remove stubborn residues or achieve a satisfactory level of sanitation. Conversely, temperatures significantly higher than 120 degrees can lead to the risk of damaging sensitive items such as plastics or can cause safety concerns, as water at high temperatures can scald. Thus, maintaining the dishwater at around 120 degrees strikes a balance between effective cleaning and safety.
