Disclosed are systems, devices, and methods, including a system that includes a sensor configured to monitor at least one parameter associated with operation of the fluid delivery device, and a controller. The controller is configured to activate a motor of the fluid delivery device, detect an occurrence of a problem in fluid delivery based on one or more first sensor signals generated by the sensor when the motor is activated in a first direction, the one or more first sensor signals representative of the at least one parameter monitored in the first direction, and determine a type of the detected problem based on one or more second sensor signals generated by the sensor when the motor is activated in a second direction substantially opposite the first direction, the one or more second sensor signals representative of the at least one parameter monitored in the second direction.
