While cooking pasta the pot of water boiled over which resulted in fire inside the stove that can be seen under the glass cook top. There was also smoke rising up from the 5 control knobs of the stove. Service was called and the repair man noticed again the smoke billowing up from the control knobs and immediately unplug the unit. We had a Viking stove top in old house and that unit can hold up to a gallon of spillage. This kitchenaid unit can't handle what I would consider normal occasional spillage of a few ounces of water. Called kitchenaid to complain and was told that it was user issue.
