Robin:

R I recently purchased a new dishwasher. My old one was bought late
R 80's.
R When I replaced the dishwasher, I forgot to mark the old power supply
R cord wires, which one was black(hot)and which one was white(neutral).
R They are not color coded but one has covered with grooved(?) gray
R rubber skin and the other one is just smooth.

I remember it as "wibbed iz white" (ribbed is white). To go further,
"wibbed iz whit iz wide" == the wider blade on the plug is the white
one.

A way to doublesheck is to take a voltmeter with one lead to the cold
water pipe (assuming copper pipe all the way) and the other to the
electric supply. One will read 120v or so, the other zero or near
zero. Could also use a test lamp.
