Why does my rice cooker keep boiling over or splashing starch?

If starch and water bubble out of the rice cooker, the batch is usually too full, the rice has not been rinsed enough, or the water level is higher than needed. Stop using the appliance if liquid reaches the controls, the cord area, or any electrical part.

How to check it safely

1. Unplug the cooker and let it cool before cleaning any spill.
2. Reduce the batch size and make sure the rice and water stay within the stated maximum content.
3. Rinse the rice in a separate container before cooking, then drain it well before adding it to the inner pan.
4. Check that the lid is seated properly and that the steam vent is clear.
5. Make sure the pan and lid are clean, because dried starch can encourage foaming and overflow.

Expected result

The cooker should simmer without forcefully pushing liquid out of the lid or vent. A small amount of steam is normal, but spillover is not.

When to stop using the product

Stop using the rice cooker if spillover happens repeatedly, if the appliance smells burnt, or if moisture has entered the base. Never use water to rinse the electrical base.

If the issue remains unresolved, or if safe use is uncertain, contact the retailer or store where the product was purchased. The retailer can explain the available next steps.
