Stainless Steel Inner Cooking Pot with Handles
The C8 error code is a firmware-level alert indicating that the installed inner pot is incompatible with the unit's thermal sensors. This model requires a specific flat-bottomed vessel to ensure maximum surface contact with the heating element; using a standard rounded-bottom pot creates an air gap that disrupts heat transfer. Replacing the vessel with the correct OEM handle-equipped version restores the required thermal resistance profile for the control board.
