I have a new (this year) dishwasher, and Ill say nothing in favor of the requirements to make dishwashers use less power. But I WILL say that our new dishwasher is that quiet that you have to look at the indicator to see if it is running. Thats not nothing.
I rather have a noisy dishwasher that actually washes dishes with plenty of hot water, than these new ones that reuse and filter the water, and use major detergents to get the dishes clean.
