Saw a different thread where there were tons of replies. Our WF218ANW/XAA front load washer just did the same thing. Went downstairs to get the wash and when the door was opened, a white misty smoke came pouring out. Pulled out the plug and then the clothes. The smoke kept coming out for about 5 minutes. So I will be digging up our purchase receipt and info to see what to do next. I think it is about 8 years old.
