Back to the 120Vac problem here, American washing machines run off
120Vac so there's not enough juice to put a heater in,

As has been pointed out, 120VAC has enough juice to heat water in a
machine to wash laundry or dishes.

If a child (or adult) contacts a live conductor, 240VAC will be a worse
problem than 120. American households can supply appliances with 240V
using conductors that are only 120VAC from ground.
