The idea that washing machines use a lot of power dates back to the 1950s to'70s when many top loaders had heating elements.
Many houses had inadequate hot water supply, the detergents didn't work well in cold water and most fabrics were cotton which cleans best at high temp.
The ones without heaters didn't use much more energy than modern ones.
