1. A dehumidifier appliance defining a vertical direction, a lateral direction, and a transverse direction, the dehumidifier appliance comprising:
a cabinet defining an airflow path that extends between an air inlet and an air outlet spaced apart from the air inlet;
a water tank removably mounted within the cabinet below the airflow path;
a first connector provided within the cabinet, the first connector comprising a pair of receiving pins and a pair of first magnets;
a second connector provided within the water tank and configured to mate with the first connector, the second connector comprising a pair of contact pins and a pair of second magnets; and
a controller in operative communication with the first connector, the controller configured to perform an operation, the operation comprising:
determining that a first circuit between the pair of first magnets and the pair of second magnets is closed;
initiating a dehumidifying cycle;
determining that a second circuit between the pair of receiving pins and the pair of contact pins is closed; and
implementing a responsive action in response to determining that the second circuit is closed.
