A beverage maker platen overflow sensing system is disclosed. The sensing system includes a process control board (PCB) in communication with solenoid valves of a manifold, the solenoid valves controlling the flow of hot water (e.g., for brewing coffee or tea) into a server positioned in a platen of the beverage maker. The PCB further includes an overflow detection circuit connected to the solenoid valves. Two signal probes are positioned near the forward edge of the platen. Similarly, ground probes are positioned in the platen below the signal probes and providing a ground path to the PCB. The overflow detection circuit generates an electrical signal between the signal probes and detects an overflow state when fluid in the platen grounds the signal between the signal probes and the ground probes. While the overflow persists, the overflow detection circuit ceases the water flow by electrically signaling the solenoid valves to close.

Beverage preparation apparatus for preparing a beverage comprising: —a water tank (2) for storing water, —a brewing unit (3) for receiving a dose of beverage ingredients, —a water line (5) for supplying water from the water tank to the brewing unit (3) including a pressure pump (4) for supplying pressurized liquid to the brewing unit and a fluid heater (29) for heating liquid, —a control unit (6) for selectively controlling the activation of the pressure pump, wherein it further comprises a fluidic interrupter (7) positionable in fluidic interruption position for interrupting the fluidic communication between the water tank (2) and the water line (5) and, reversely, positionable in fluidic communication position for restoring the fluid communication between the water tank and the water line and wherein the control unit (6) is arranged for automatically activating an anti-freeze mode by activating the fluidic interrupter (7) in fluidic interruption position and by running the pressure pump (4) to at least partially empty the water line (5) from water contained therein.

A beverage maker may comprise a heating system, a temperature sensor operably coupled the heating system, and a controller. The controller may be configured to receive a series of measured temperature signals from the temperature sensor, calculate a change in temperature using the series of measured temperature signals, and calculate an efficiency of the heating system based on the change in temperature. The controller may further estimate a scale buildup based on the efficiency of the heating system, and store at least one of the estimated scale buildup or the efficiency of the heating system in a heating system performance database.
