What is the purpose of the HI-TEMP WASH option?

When the HI-TEMP WASH option is selected, the dishwasher heats water in the main wash to approximately 140°F (60°C). This increase in water temperature helps the dishwasher detergent remove food grease and soil from dishes more effectively and aids in drying. HI-TEMP WASH can be used with all cycles except RINSE ONLY and is automatically provided when the HEAVY WASH cycle is selected.
