Possibly one of the worst examples you could have chosen. Washing machines did not replace anyone's job. There was no army of laundry ladies going house to house to do the laundry, it was the housewife doing the laundry.
Washing machines gave the housewife a bit more time to do the other chores, such as cleaning and cooking. No jobs were lost, and jobs were created because you had the people repairing the things that didn't exist before.
