My washer stopped working last week, did the homework and everyone said coupler, so i changed it. plugged it in and working great.... untill i hear a clicking noise, walk over and smells like its on fire, (rubber).. so i turn it off and investigate.. cant find anything, turn the knob turn back on and it keeps going, and so does the smell.. i turn it off again and this time when i try to turn it on it will not come on, just makes a strange noise like its stuck or somthing.. try again serveral times and finally comes back on.. i open lid and shut it and back to not working... any ideas?
