Samsung Refrigerator autofill not filling. C76 error code on control panel

[usernCHrjdctNf]

My samsung refrigerator is less than 2 years old. The autofill pitcher stopped filling two days ago. Then I got an error code that said PC CH and today it changed to C 76 and it is flashing. Does anyone else have this problem? I read a few things but I am not sure what to do.

Hey, give this link a shot: https://www.samsung.com/us/support/troubleshooting/TSG01201488/ If this does not help I recommend letting a service technician have a look. Send your full model code and serial number via private message or call 1-800-SAMSUNG directly to get started.
