How can I fix my washing machine which won't start, Maytag, Admiral?

How can I get my washing machine to start. I had the machine on when I was adding clothes to it. I stopped the machine, with the push pull knob, because the water level was getting about 1/2 to 3/4 full. I put the rest of the clothes in it. I then closed the lid and tried to start it. It didn't start. I emptied the clothes--it still wouldn't start. I emptied the water it still won't start. I took the rear control cover off to look for loose parts or wires. All controls/cables look fine. The wall socket has power. What can I do.
