Whirlpool Top Load Washer Fills With Water and Stops, Won't Drain

My Whirlpool Top Load Washer Fills With Water, Stops and Doesn't Drain Even Though the Knob Continues to Turn. If I Turn the Knob to Drain, it Will Drain for MAYBE 10 Seconds and Then Stops Again. I Thought it Might be the Lid Starter Switch, so I Looked at it and one of the Connections Appers to be Discolored, Almost a Burnt Brown Color. Could this Be the problem? If not, what do you think it could be?
