1. A method of detecting a leak in a refrigerator appliance, the refrigerator appliance comprising a cabinet, a food storage chamber defined in the cabinet, a water supply line, a water filter coupled to the water supply line, and a sensor embedded in the water filter, the method comprising:
measuring, by the sensor embedded in the water filter, water pressure in the water filter;
measuring, by the sensor embedded in the water filter, flow through the water filter;
receiving, by a controller of the refrigerator appliance, the pressure measurement and the flow measurement from the sensor;
monitoring the water pressure in the water filter by receiving a plurality of pressure measurements over time;
monitoring the flow through the water filter by receiving a plurality of flow measurements over time;
calculating a rate of change in the plurality of received pressure measurements over time;
calculating a rate of change in the plurality of received flow measurements over time; and
detecting a leak based on the received pressure measurement and flow measurement based on an increase in at least one of the rate of change in the plurality of received pressure measurements over time and the rate of change in the plurality of received flow measurements over time.
