Query: Bella Cucina

Well this is a scary surprise. I was just on the computer upstairs and heard something running but thought it was neighbor mowing lawn. Sounds was going about 10 minutes so I go check and the blender is running all by itself (nobody else here with me). I could smell something burning and had to unplug unit. It was very hot and I am pretty sure it would have caught on fire eventually. This is very alarming as the blade was not on the unit and it was just the motor sitting by itself. My wife used blender about 4 hours ago but that was its last use. Wow !!Just happended to be next to some protein containers and some other plastic. Also, right underneath wooden cabinets.Perfect fuel for a house fire.
