Rice cooker spitting starchy water or boiling over even when you measure carefully? A clogged steam vent is a common culprit. When steam cannot escape the top, pressure pushes water out the sides instead.

How to Clean the Steam Vent
- Remove the vent cap. Most caps lift or twist off the lid.
- Soak and rinse. Wash it in warm soapy water to dissolve starch.
- Clear the opening. Use a brush or toothpick to clean the hole through.
- Reassemble. Dry and refit the cap before the next use.
Pro Tip: The vent cap is a part most people never remove, so starch quietly hardens inside. Cleaning it every week or two prevents most boil-overs and spitting.

Because a blocked vent forces water sideways, it helps to check related overflow issues, and reviewing a cooker that bubbles over or a leaking lid can confirm the vent is the cause. Overflow onto the plate can also create a burnt smell.
When to Call a Pro
The vent is fully DIY. If cleaning it does not stop boil-overs, revisit your rinsing and water level rather than any internal repair.
