I will think about using the existing 240v circuit for the clothes dryer to run a sub panel, then run separate circuits for the dryer and the dishwasher from that. Come to think of it, I have another potential 240v appliance to add later (commercial two head espresso machine) so a sub panel might be the best approach.

The dishwasher has a booster heater, takes hot water and heats to 180 F for the rinse cycle, hence the power requirements.

My Bosch has a supplemental heater to 180F as well and it is 1500 Watts.
