Kenmore DW dead -- yes, I've checked power
Yes, indeed, I made sure early on that there was 120VAC to the box under the DW.
Regarding the "power cord" I'm not sure what you mean. But I'm sure there is 120v AC arriving up at the switches behind the front panel. If I hold my voltage detector (a little pen-like device that beeps when touched to electrical cables carrying a load) near the switch wires, it screams loud and clear.
