Abstract
The method for regulating pressure in a beverage brewer as disclosed herein includes initiating a brew cycle, which initiates a feedback loop. A temperature sensor monitors the water temperature in a heater tank, and one or more heating elements activate to heat the water to the appropriate temperature if necessary. An ammeter monitors the amperage of an electric current drawn by a pump. If the amperage is above a current ceiling, a voltage regulator reduces the voltage of electric current supplied to the pump, thereby reducing the pressure in the brew cartridge. The voltage regulator increases the voltage of electric current supplied to the pump to increase pressure in brew cartridge if the amperage of the electric current is below a current floor. Once the voltage regulator adjusts the voltage, the ammeter monitors the amperage of the pump.
