Using a dishwasher can be up to 5x more water-efficient than hand washing. Hand washing one load of dishes can use 20 gallons of water, whereas water- and energy-efficient dishwashers may use as little as four gallons.[1]

Can is doing an awful lot of heaving lifting there.

Given that my sink cannot contain 20 gallons of water and that I do not even fill my sink full to do my dishes by hand, I cannot possibly be using 20 gallons of water to do my dishes when I do my dishes by hand.

it really depends how you do it, I don't think one serious non biased study has ever been done. probably an ultrasound bath is the most energy and water-efficient method
