First, excuse me for my non-native english. Now...
Not the same model, but I had the same problem. It turned out there was water in the bottom of the dryer. After removing the water container, I could use my relatively long arms to reach down to the foundation at the back of the dryer. There, I felt about a centimeter of water. I used towels and paper to dry it up, and after that it worked just fine.
Turn of electricity/unplug dryer first though:)
