A method of descaling a water dispensing system included in a refrigerator appliance with a water dispenser is disclosed. The method of descaling includes the step of removing a water filter cartridge from a filter port of the refrigerator appliance wherein the filter port is in fluid communication with the water dispenser. The method also includes the step of inserting a descaling cartridge containing descaling fluid into the filter port of the refrigerator appliance. The method further includes the step of advancing the descaling fluid from the descaling cartridge through the water dispenser.

1. A method of descaling a water dispensing system included in a refrigerator appliance with a water dispenser, the refrigerator appliance including a main valve configured to receive pressurized water from a domestic water source, a water heating assembly, a hot water valve openable to advance wate
1. A method of descaling a water dispensing system included in a refrigerator appliance with a water dispenser, the refrigerator appliance including a main valve configured to receive pressurized water from a domestic water source, a water heating assembly, a hot water valve openable to advance water from the main valve to the water heating assembly, a user interface, and a controller electrically coupled to the hot water valve, the water heating assembly, and the user interface, wherein the controller is configured to (i) reconfigure a display to request a descaling cycle, (ii) receive a user input from the user interface requesting a descaling cycle, and (iii) open the hot water valve in response to the user input requesting the descaling cycle, the method comprising: removing a water filter cartridge from a filter port of the refrigerator appliance, the filter port being in fluid communication with the water dispenser,inserting a descaling cartridge containing descaling fluid into the filter port of the refrigerator appliance, andadvancing the descaling fluid from the descaling cartridge through the water dispenser. 2. The method of claim 1, further comprising the step of advancing the descaling fluid through a water heating assembly. 3. The method of claim 1, wherein the descaling fluid from the descaling cartridge is advanced through the water dispenser in response to a user input received by the user interface initiating a descaling cycle. 4. The method of claim 3, wherein the user interface displays information indicating scale build-up in the water dispensing system. 5. The method of claim 4, wherein: the water dispensing system includes a pressure sensor, andthe user interface is configured to display information indicating scale build-up in the water dispensing system in response to the pressure sensor measuring a threshold pressure. 6. The method of claim 4, wherein: the water dispensing system includes a temperature sensor situated between the water heating assembly and the water dispenser, andthe user interface is configured to display information indicating scale build-up in the water dispensing system in response to the temperature sensor measuring a threshold temperature. 7. The method of claim 3, wherein the user interface is configured to display information indicating that the descaling cycle is complete after fluid from the descaling cartridge is advanced through the water dispenser. 8. A domestic refrigerator appliance comprising: a main valve configured to receive pressurized water from a domestic water source,a water heating assembly,a hot water valve is openable to advance water from the main valve to the water heating assembly,a dispenser coupled to the water heating assembly,a descaling cartridge containing descaling fluid in fluid communication with the water heating assembly,a user interface, anda controller electrically coupled to the hot water valve, the water heating assembly, and the user interface, wherein the controller is configured to (i) reconfigure a display to request a descaling cycle, (ii) receive a user input from the user interface requesting a descaling cycle, and (iii) open the hot water valve in response to the user input requesting the descaling cycle so that descaling fluid is introduced into water advancing through the water heating assembly and the dispenser. 9. The domestic refrigerator appliance of claim 8, further comprising a fluid pressure sensor in electrical communication with the controller. 10. The domestic refrigerator appliance of claim 9, wherein the controller is configured to display the request for the descaling cycle in response to the fluid pressure sensor indicating a pressure above a first threshold pressure. 11. The domestic refrigerator appliance of claim 10, wherein the controller is configured to lock the hot water valve in a closed position in response to the fluid pressure sensor indicating a pressure above a second threshold pressure until the controller receives the user input from the user interface initiating the descaling cycle, the second threshold pressure being greater than the first threshold pressure. 12. The domestic refrigerator appliance of claim 8, further comprising a fluid temperature sensor in electrical communication with the controller and situated between the fluid heating assembly and the dispenser. 13. The domestic refrigerator appliance of claim 12, wherein the controller is configured to display the request for the descaling cycle in response to the fluid temperature sensor indicating a temperature between the water heating assembly and the dispenser above a first threshold temperature. 14. The domestic refrigerator appliance of claim 13, wherein the controller is configured to lock the hot water valve in a closed position in response to the fluid temperature sensor indicating a temperature between the water heating assembly and the dispenser above a second threshold temperature until the controller receives the user input from the user interface initiating the descaling cycle, the second threshold temperature being greater than the first threshold temperature. 15. The domestic refrigerator appliance of claim 8, further comprising an inlet temperature sensor, located near the inlet of the water heating assembly and in electrical communication with the controller, and an outlet temperature sensor located near the outlet of the water heating assembly and in electrical communication with the controller. 16. The domestic refrigerator appliance of claim 15, wherein the controller is configured to disable the water heating assembly in response to detection of a temperature difference between the inlet temperature sensor and the outlet temperature sensor outside a predetermined range. 17. The domestic refrigerator appliance of claim 8, further comprising a filter port interposed between the main valve and the water heating assembly, the filter port being configured to receive the descaling cartridge. 18. The domestic refrigerator appliance of claim 8, wherein the controller is further configured to determine if a descaling cycle is desirable, and wherein reconfiguring the display to request a descaling cycle includes reconfiguring the display to request that a user initiate a descaling cycle if the controller determines that a descaling cycle is desirable. 19. The domestic refrigerator appliance of claim 18, further comprising: a fluid pressure sensor in electrical communication with the controller; ora fluid temperature sensor in electrical communication with the controller, wherein the controller determines if a descaling cycle is desirable based on a pressure indicated by the fluid pressure sensor or a temperature indicated by the fluid temperature sensor.
