Abstract
A beverage brewing apparatus which includes a heated water reservoir, a heating element retained in the reservoir, and a thermostatic and a low water sensor configuration positioned in a heat exchange relationship with the heated water reservoir. The thermostatic and low water sensing configurations position the temperature sensors outside of the water reservoir to prevent the heated accumulation of mineral and other deposits thereon. A niche is formed in the wall of the heated water reservoir for receiving the thermostatic sensor configuration. A retaining cover is positioned over the niche to enclose the thermostatic sensor configuration in the niche. A portion of the niche against which the sensors are positioned is thinned in order to more accurately read the corresponding temperatures.
