How to set auto timer?

SOURCE: Spoiled rice after 20+ hours

Our rice cooker would keep the rice from spoiling for about two years and then all of a sudden it wouldn't keep for even 12 hours before the "spoiling" smell would be present. I tried really washing every washable part and even did an alcohol wipedown in case it was a bacterial or something, but nothing worked. I liked the cooker before this started happening, but don't want to buy another one because it is so expensive. When I was in Japan, there are some REALLY good ones that would monitor the moisture level and want one of those, but will have to live with what is available here. Anyone got a solution?

I also have this problem and I fixed it by adding in a little more water and by removing the power cord from the outlet immediately after the cooker finishes it's cycle. Not ideal, but it does save my rice.

It's not meant to keep in there for a few days. A few hours would be the max, say for a party for instance. When you are done with the rice, take it out and put it in your refridgerator.

if cooking rice is your problem. you must first fill your rice cooker with rice and rinse it with water to remove excess starch when your done removing the excess starch you will have to add water for every cup of rice, 1 1/2 cups water or you can try 1:2 ratio (1 cup of rice: 2 cups of water). same goes to any other cuisines. i hope you find my solution helpful.
