Abstract
A beverage brewer has an electric flow-through heater operable in two power steps. In a first embodiment of the invention, the first and second pilot lamp (15 and 18, respectively) light up when the flow-through heater is operated at its upper and respectively, lower power step, while in a second embodiment of the invention, the first pilot lamp (15) indicates the ON condition of the flow-through heater and the second pilot lamp (18) lights up when it is operated at its lower power step. Both embodiments have in common that the second lead (20) of the second pilot lamp (18) is dead-ended when the second switch (12) is open, and is not connected to the secondary conductor (11) until the second switch (12) closes.
