No, but they are better designed in ways that allow them to clean well with lower power consumption. The tub is better insulated for example and they don’t waste energy on a heated dry cycle. That energy allowance can be better utilized in the main cleaning cycle.

We had drying issues with our Miele that was addressed by using the rinse agent. Now generally dry results.

Are there new 2023 requirements? In the past, the only thing that DOE requirements applied to was the "Normal" cycle. All others can use as much water as they want since DOE regs don't apply.

It should work fine at 240V, 60Hz without issues.

AC motors are famously sensitive to power frequency. It's not the same as resistive loads. I'll definitely do some research, however.

I imagine there are some Japanese ones from the 60Hz half of Japan (you read that right, yes) that might fit the bill, too.
