It is supposed to connect to the white wire, the black wire, and the green grounding screw on the dishwasher.
I can get the green to green, but what do I do about the two other un-identified wires.
Does it not matter which one goes to which?
The smooth side of the pigtail will go to black, and the ribbed side wire will go to the white wire.
I just did same thing for electric stove. New pigtail didn't have any color coding at all. Connected the center to the ground, the two others to the connectors on either side. Electrician who came in to install a different outlet (one of the older three prong outlets instead of the newer four prong boxes), said it doesn't matter with alternating current, as long as ground is correct, and on almost all applicances, ground is either center of three or a totally separate screw, always green on at least one of the two connections, usually on the appliance., Just make sure you have your connections tight. Otherwise, you will get some graying of your connections and a deal of resistance since the connection isn't conveying the power correctly.
Yes it matters! It sounds like you are dealing with 110 volts. The white wire goes to the silver screw and the black wire goes to the brass colored screw. One might be marked "common" that would be the white wire,the other might be marked "hot" that would be the black one.
If it is 220 it does not matter but 220 usually does not have a white wire.
USA Yes, it is important to hook it up correctly. I am glad you thought to ask. Look to see if the wires are identified with a black and /or a white stripe along the covering. If not, look at the prongs on the plug. The ground is round or U shaped. There will be two flat prongs. One prong will be wider than the other, and will only fit one way into a receptacle that has matching slots. This is called a polarized plug. The wider prong is the neutral ( white side ) and the smaller prong is the hot (black).
yes it matter because if it could shack when flour get wet
