How do you open the base of the rice cooker?
There is an interface at the edge where the rice cooker has a vertical seam around it and can be pried at the joint with the base. Hammer it directly with a screwdriver. There's a clip on the base. It should be three. But you probably don't have much use to open it, because there is a little gap between the bottom and the base, but the chances of seeping are very small.
Do you have a high pressure model or a regular one? There is a common type of screw under a self-adhesive trademark, joint barrel is opened it to see a screw, it will be able to take off.
Tear the mark and you'll see the screws open,You can turn the screw below the mark and turn the base in clockwise direction.
