<p>Various methods are disclosed for resetting a stalled pump in a fluid dispensing system. In one embodiment, it is determined whether a refill container is received in the dispensing system and then a pump actuator is moved to a loading position when the refill container is removed. Another method sets a run timer, starts a pump actuator, determines whether the pump actuator is still dispensing fluid from the fluid dispensing system upon lapsing of the run timer and then moves the pump actuator if the pump actuator is still dispensing upon the expiration of the run timer. And another method detects opening of a cover, energizes a motor to move an actuator to a loading position, determines when the actuator is at the loading position and then turns the motor off.</p> |
