A dishwasher cycle typically runs anywhere from about 1.5 to 4 hours, depending on the cycle type, dishwasher model, soil level of the dishes, and water temperature. Normal wash cycles usually take between 1.5 to 2.5 hours, quick wash cycles about 30 to 60 minutes, and heavy-duty or sanitize cycles can last from 2.5 to 4 hours or more. Some cycles add extra time for high- temperature washes or energy-saving modes, making the total run time longer. Sensor-based cycles adjust run time based on how dirty the dishes are, which can also affect the duration.
