Rice burning on the bottom

The Manual for the Rival RCS200 Rice Cooker can be found here:
http://www.rivalproducts.com/manuals/MANUALS/RCS200_43_68557881.PDF
Make sure you are following the directions for the correct amount of water to rice.
It could be that your unit is not switching from cooking to warming at completion of the cooking cycle. It should automaticaly turn to the Keep Warm Setting when it detects a temperature of 212 degrees F.
The manual advises that there are no servicable parts. If this is a new appliance I would recommend returning it to the point of purchase. If this is not possible try contacting Rival Customer Service to see if they are willing to assist with replacement or repair: See here:

Try adding a little salt to the water.

plse rate the solution if it helps you

you should have a "lever: you push down to cook and it will "pop" up when the rice is finshed, your cooker holds 6 Cups cooked rice, use 2 cups medium grain rice/ 3 cups water this should yeild you 6 cups of cooked rice, let sit about 4 min after the lever pops up to allow rice to finish steaming

The manual is on the site listed below (its the company's website):

Try this:

• Before cooking, rinse rice in warm water until water becomes clear. Then place the rice in the inner pot with fresh water.
• Take care to use proper water to rice ratios.
• Use a 1:1 ratio of rice to water plus ½ cup of water for white rice and a 1:1 ratio plus ¾ cup of water for brown rice.

Here's all the info I've been able to find:

The older Rival rice cooker steamer should have a base, a lid, steamer basket, and rice bowl.

To cook rice, fill center basin of base with water. Place the rice bowl on basin. Add rice and water as follows. For white rice add water in a 1:1 ratio to rice plus 1/2 cup. For brown rice add water in a 1:1 ratio to rice plus 3/4 cup. Examples: 1 cup white rice, 1-1/2 cup water; 2 cups brown rice, 2-3/4 cups water. Put lid on and plug in and in about 50 minutes you should have delicious rice.

Timing is Everything
Whether using the Rival Steamer for a main dish or for a side dish, cooking is easy. But not Fast. Rice and steamed vegetables actually take twice as long to cook in this steamer. The simplicity comes since you add your rice or vegetables in one step. No waiting for one thing to happen before you can do the next. Put water and fruits, vegetables, fish, poultry or rice in the basket or bowl that come with the unit, cover, plug in and wait for the light to go off per the timing chart.
1/4 cup water takes 6 -7 minutes
1/2 cup water takes 10-12 minutes
3/4 cup water takes 16-17 minutes
1 cup water takes 19-22 minutes
1.25 cups water takes 24-26 minutes
1.5 cups water takes 26-30 minutes
2 cups water takes 38-39 minutes
2.5 cups water takes 43-44 minutes
3 cups water (max fill) takes 45-50 minutes.

Steamed Chocolate Pudding (From the Rival Steamer Guide)
3/4 cup flour
3/4 teaspoon baking powder
1/4 teaspoon salt
1/3 cup butter
1 teaspoon vanilla
1/2 cup sugar
1 egg, beaten
1.5 ounces unsweetened chocolate, melted
1/2 cup milk
1/4 cup chopped nuts
Sift together flour, baking powder and salt; set aside. Cream butter and vanilla until fluffy. Gradually add sugar, beat well. Add egg and melted chocolate; blend well. Add milk alternately with dry ingredients and beat until smooth. Fold nuts into batter. Pour into greased 8"x4" loaf pan. Cover pan with aluminum foil. Place pan in steamer basket. Cover and steam until wooden pick inserted near center comes out clean. Serve warm with **Marshmallow Cream Sauce. Water: 1 cup. Time: 19-22 min.

**Marshmallow Cream Sauce:
16 large marshmallows
1/3 cup cream
In a small saucepan, combine ingredients and melt over low heat. Serve over Steamed Chocolate Pudding.

You are an *******....Just to be blunt....This person is asking how to cook the rice to water ration in the rival 6 cup rice cooker and that ratio is like other ways to cook rice, which you are completely wrong about maybe you should take some lessons on how to cook. Its 1 PART RICE TO 2 PARTS WATER....NOT EQUAL, and in the cooker its 2 cups rice and 4 cups water makes a perfect pot!

that is common to have the bottom part burn when cooking rice.

what i did was change the ratio of 5 cups water = 4 cups rice.

when its near cooking, dont leave it for a long time since it will continoiusly heat up in the bottom part, i suggest to unplug it when the rice is already cooked.

hope this will help.

Your cooker, along with mine, cooks very hot. If it is new then you can take it back, but if you want to cook with it then you need to stir the rice often. About every 5 minutes should be good. As soon as it is done you need to remove it from the cooker. Let's see how that works.
