My washer is flashing the code FL. What does this mean?

My Kenmore Elite HE 3t is doing the same thing but it is beeping "dL,F" It's driving me crazy and I am unable to do wash. I phoned the appliance guy who we bought the washing machine from so when I resolve this matter hopefful soon I will let you know. Please let us know if you were able to fix the problem. Thanks, Dawn
