Kenmore Front Load washer HE2t

My Kenmore front loading washer is 1 1/2 years old, and has quite. I have never been so frustrated in my life, I have received absolutely no help from Kenmore. They said, Oh thats to bad…
I turn on the power, choose the cycle, push start and the ERROR code F-01 is displayed. I have read the troubleshooting manual, and unplugged the machine overnight, tried the door, but it continues to display F-01. If anyone can help, I would so appreciate it. This will be the last time I purchase an appliance from Sears. I am to make my final payment on the machine next week…the payments outlast the product.:mad:
