The average drying time for dishes in a dishwasher can vary depending on several factors, including the dishwasher model, the selected drying cycle, the water temperature used for the wash, and the materials and shapes of the dishes being washed.
Older dishwasher models without advanced drying features might take anywhere from 30 minutes to an hour to complete the drying process. However, more modern dishwashers often have improved drying capabilities, which can significantly reduce the drying time. Some high-end dishwashers use condensation drying or heated drying methods, which can complete the drying process in as little as 15-20 minutes.
Additionally, if you use a dishwasher rinse aid, it can help to speed up the drying process by promoting water sheeting and reducing water droplet formation on the dishes.
Keep in mind that the energy efficiency settings on some dishwashers may extend the drying time to save energy, so the actual drying time can vary depending on the settings you choose.
For the most accurate estimate of the drying time, it's best to refer to the user manual or specifications of your specific dishwasher model, as different machines can have different drying capabilities and settings.
