Why does the keep warm function leave the rice cool around the edges?

If rice feels cooler around the edges in keep warm mode, the portion may have been spread too thin, the lid may have been lifted for too long, or the rice may have cooled during a delay between cooking and serving. Keep warm is designed to maintain temperature, not to re-cook rice.

Check the serving set-up

1. Confirm the cooker has finished the cook cycle before using keep warm.
2. Fluff the rice gently and replace the lid promptly after serving.
3. Avoid leaving the lid open for long periods, because heat escapes quickly.
4. Check that the bowl sits flat and that the cooker is placed on a stable surface with free space around it.
5. Try a smaller serving delay next time and compare the result.

What the observation means

If the rice stays evenly warm after a short delay, the issue was probably caused by serving time rather than the appliance. If the edges cool very quickly even with the lid closed, the cooker may not be retaining heat properly.

When to stop using it

Stop using the rice cooker if keep warm is accompanied by a burning smell, overheating, or repeated switching behaviour that makes the appliance unsafe to leave unattended. If the issue remains unresolved or safe use is uncertain, contact the retailer or store where it was purchased.

The manuals describe a keep warm function and power indication lights, but they do not indicate that keep warm should bring cold rice back to serving temperature, so expectations should stay modest and practical.
