My dishwasher is plugged in and there is power going to the plug, but I am not getting any lights or anything on my dishwasher!

You can still have a wire that has come loose or a bad door switch. There is no substitute for taking a meter and tracing out the wires to find the break. Look at this: https://dl.dropbox.com/u/8010163/Kenmore_Ultrawash_Dishwasher.pdf
Hope this helps.
