Abstract
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.
