XFINITY RDK error codes are codes that apply to the XFINITY X1 Entertainment System. These codes alert the user that something is not functioning properly.
There is a search engine on the XFINITY Customer Support website that allows the user to find and troubleshoot an error code. By typing in the user code, the user can pull up directions on how to resolve the issue. If the error code still appears, or if a new error code occurs, contact customer support, or search the site's XFINITY X1 support forums, where users use message boards to post problems and solutions to error codes.
