Why does my rice cooker click or crackle when the bowl is heating up?

A light clicking or crackling sound during heating is often caused by moisture on the outside of the inner bowl, or by the normal expansion of parts as they warm up. If the sound is loud, repeated, or accompanied by burning smells or unusual behaviour, stop using the rice cooker and check it before you cook again.

What to check first

1. Switch the rice cooker off and unplug it. Let it cool fully.
2. Remove the inner bowl and dry the outside carefully with a soft cloth. The manual notes that remaining moisture on the bowl can cause a cracking noise while the unit heats up.
3. Check that the bowl is seated correctly in the cooker and that no rice grains or water are trapped underneath it.
4. When you retry, use the measuring cup and the water level marks, and make sure the rice is washed and drained before cooking. Unwashed rice can lead to poor results and extra steam build-up.

What the result means

If the noise disappears after drying the bowl and refitting it properly, the cause was likely harmless moisture or incorrect seating. If the sound continues, gets louder, or is joined by smoke, unusual odour, or failure to heat properly, stop using the appliance.

When to stop using it

Stop using the rice cooker immediately if you hear sharp repeated cracking with visible damage, scorching, or any sign of electrical fault. If the issue remains unresolved or safe use is uncertain, contact the retailer or store where it was purchased.

For normal use, keep the cooker on a flat stable surface with free space around it, and always fit the lid so steam is directed away from the handle. The models listed in the product data include boil-dry protection and indicator lights, but those features do not replace basic checks for correct bowl placement and dryness before cooking.
