Can i connect my Hoover HD73M Dishwasher to a cold feed?

First off, you need a hot water feed line for your dishwasher, not cold water

Secondly, if you have a garbage disposal installed on your sink you can connect the dishwasher drain hose to the side port on the garbage disposal. That's what that little port is for anyway. If you do have a garbage disposal and hook the dishwasher hose to it then make sure you take a hammer and screw driver and knock out the little plastic plug that's inside the garbage disposal port before hooking up the hose to it, if you don't you'll flood your kitchen.

If you don't have a garbage disposal on your sink, then you're going to have to replace a piece of your sink's drain piping with a wye (Y) tailpiece. The tailpiece has a small branch that comes off it to where you can connect the dishwasher drain hose.

Regardless of which way you hook up the drainage and water lines, make sure you test out the work you did by running the dishwasher and keeping an eye on it. I can't tell you the number of times i've seen people hook up stuff like this and not test it and then when they go to use the dishwasher it floods the kitchen..... usually when people are sleeping at night. Test your work.
