don't know about you but my dishwasher's shortest program is ~30 minutes - if price of electricity changed every minute, i just wouldn't care because it'd be pointless.

Most of the energy a wash cycle uses is for heating the water it just took in. The part where it splashes the water around uses next to nothing.
Waiting a bit to start heating that water if there's a high consumption peak right now is hard to transfer to any significant benefit for the consumer, because electricity is just that cheap. But it might make sense from the grid point of view to have higher demand elasticity.

For example a dishwasher could have a setting where you tell it what time the washing must be done by, and it schedules the wash cycle to be when it thinks electricity will be cheapest.
