Answer 1

In ECO mode, it uses less water than during a fast wash. It uses less energy but takes slower. A dish washer can reuse the water during the long wash.

To think of it a different way, if you drive 0 to 60 miles per hour in 4 seconds, you will waste a lot more gas than driving 0-60 MPH in 20 in 10 seconds as you are slowly building up to the speed. Or if you drive 0-30 MPH in 10 seconds, and stay at the 30 MPH speed, you will save more gas. So slower can save more energy, even if it takes longer.
