    Mar 22 2015 · Cycle time. It s the average time it takes to complete a step or set of steps within an operation. The cycle time for the washer is 30 minutes while the cycle time for the dryer might be 45 minutes to an hour. In a 10-washer operation the cycle time for a single load would be three minutes (30 minutes divided by 10 washers).
