  • Methods for resetting stalled pumps in electronically controlled dispensing systems
    Patent number: 8651329
    Abstract: A system and related method is disclosed for resetting a stalled pump in a fluid dispensing system. In one embodiment, the presence of a user's hand is detected to start a pump actuator associated with a refill container. A controller associated with a motor actuates the pump actuator by rotating a motor shaft in a first direction. The current sensor is monitored and when the current sensor detects a predetermined level of current the motor shaft is reversed to a starting position.
