Abstract
A method for determining a false reporting of a liquid level detection in a system including a container configured to hold a liquid to a first liquid level in the container, a heater disposed within the container, the heater configured to heat at least a portion of the liquid, a temperature sensor disposed above the heater within the container, the temperature sensor configured to sense the temperature of its surroundings, the method including effecting the heater for a duration; determining the rate at which the temperature rises; and comparing the temperature rise rate to a liquid temperature rise rate threshold, wherein if the temperature rise rate is greater than the liquid temperature rise rate threshold, the temperature sensor is determined to not have been submerged in the liquid and a reporting of the liquid level detection in the system is deemed false.
