    Your description is unclear, but let me tell how it should be.

    If there is a flex coming out the wall, it should have 3 wires: hot, neutral and ground. You can identify them by the colors. You connect each wire to the appropriate wire in the new dishwasher. Ground is required.

    I'll assume you mean that the old dishwasher had a power cord that plugs into a wall outlet (probably under the sink).

    In the connection box under the new dishwasher, there will probably be a green screw. Connect the green (ground) wire from the power cord to the green screw in the connection box.

    Be sure to use a knockout clamp (aka loom clamp or romex clamp) to securely hold the cord, you don't want to put stress on the wire nuts.

    There is a video about that very subject on Ask This old House and if you can't play it on this website then try http://www.pbs.org and look for videos and the This Old House videos both This Old House and Ask This Old house are on the same page. Looking for colors on a plug are important but sometimes there are no colors to guide you. Richard Trethewey guides you in how to install the plug the right way. Good luck to you!

    yes, connect the ground wire of the cord to the metal of the DW. There should be a ground screw close by. If not you can add one or use the metal clamp method described above.

    FWIW we put plugs/cords on all our DW installs.

    first thing's first you have to make sure your appliance is earthed lest you risk getting a quick afro there.
