What to do if my Sunny SF-T7971 shows E01 or E13 error?

If your Sunny Treadmill is showing an E01 or E13 error, it indicates a message failure. Check the wire connections from the console to the bottom control board. If a wire is punctured or damaged, replace it. If the problem persists, you may need to replace the bottom control board.
