Keep-warm function overheats food, causing it to dry out or burn on the bottom.

Safety first: Allow the cooker to cool before inspecting internal parts.

Steps to mitigate:

• Add liquid: Ensure there is sufficient liquid in the pot before enabling keep-warm; very small quantities can burn.
• Stir and serve: Avoid leaving food on keep-warm for extended periods; transfer to another container if needed.
• Check pot and heater cleanliness: Clean the bottom of the pot and heater plate to ensure accurate temperature sensing.
• Test with water: Run keep-warm with only water and measure temperature with a kitchen thermometer; if excessively high, sensor or control issues are likely.

When to call a technician: Persistent overheating on keep-warm suggests a sensor or control board fault that should be professionally diagnosed.
