I don't doubt that, and I've considered replacing it. The lifespan of a "modern" dishwasher is about 10 years, a far cry from the 30 years that mine has run. In the time that I've had mine, I would have had to replace a modern one about three times. I think that new ones would be more water efficient, but I do not see new ones being more efficient electrically. Mine is plumbed to hot water, so the heating elements are not used much and it dries them with blown air instead of heat. If I am looking to reduce my electrical footprint there is much lower hanging fruit than my dishwasher. How much energy would go into the manufacturing, delivery, and installation of three dishwashers?
