Dishwasher as largest motor load?

[Ryan Ray]

If the only appliance with a motor is the dishwasher, is it calculated at 25% as the largest motor or is it ignored due to the load being partly heat?

I would not. I would wire the DW based on the DW nameplate. Same as an AC unit you follow the nameplate the calculations are already done for you. But I could be wrong.

I would expect the heating element in a dish washer to draw more than the pump. You won't know the size of just the motor to know what it is.

No refrigerator? No HVAC? No clothes dryer?

The dryer can't be used as the largest motor load and there is AC in the load calculation, but the AC was omitted due to the heat being the larger load. It looks like you still use the AC motor if it's omitted and the largest motor.
