A:Answer Good question EricaI. Your dishwasher can average 2-3 hours per load, but uses nearly 40% less energy than older models. The average length of time for a normal cycle can be anywhere from 1 hour to 3 hours. As your dishwasher may be equipped with sensor technology, the very first cycle may run longer to calibrate the sensor. Please keep in mind that selected options add time to the cycle. Also, cooler water temperatures cause the dishwasher to run longer while heating the water. You can try running the nearest hot water faucet until it gets hot just before starting the dishwasher. Also, be sure the water heater in the home is set to 120 degrees F for best performance.
