E9 appears and the cooker shuts down unexpectedly, often with a burning smell previously noticed.

Safety first: Immediately unplug the cooker. Do not attempt to restart until it has fully cooled and been inspected.

• Inspect inner pot and heating plate: Remove the pot and check for severe scorching or melted non-stick coating. Clean any burnt residue carefully. If the pot is badly warped or coating is peeling, replace the pot.
• Check vents: Examine side and bottom vents for dust buildup or obstructions. Clean with a soft brush or vacuum.
• Smell test: If you smell burnt plastic from the base or see melted areas, do not use the cooker again until inspected by a professional.
• Test with water only: After full cooling and cleaning, add water to the minimum line and run a low-temperature program. If E9 reappears quickly, internal safety components may be damaged.

Because E9 indicates a serious overheat, internal thermal fuses, wiring, or insulation may be compromised. Have the unit professionally serviced or replaced; do not bypass safety devices.
