I have a Tiger Brand rice cooker and it used to keep my rice fresh for three days. I have had it for four years and within the last week, my rice starts to turn slimy and smell musty after a day. What is causing this? I have a Tiger Brand rice cooker and it used to keep my rice fresh for three days.

I PLUG IT AND NO START NO LIGHT. I PLUG IT AND NO START NO LIGHT.

Three to four years ago cooked rice would be edible up to 7 days (more or less) in my cooker on my counter. Since then different brands of rice I've purchased have been coated with a substance that is essentially impossible to wash off prior to cooking and contributes to rapid spoiling. I have been to many other sites that attribute the spoilage to improper cleaning and hygiene... Nowhere have I seen anyone attribute the spoilage to the true cause! It makes me wonder who these people and who is paying them? Three to four years ago cooked rice would be edible up to 7 days (more or less) in my cooker on my counter.

I have the same problem with a new Zojirushi Rice cooker. Talked to Zojirushi Tech person and they say that the silicone gasket got contaminated. The Government about 10 years ago changed the law on the silicone formula that can be used on food appliances used in the sealing gasket. The rice in my old cooker lasted to 60 hours before it got hard. Tech said once the gasket gets contaminated it will contaminate the new batch of rice. My new one was good for 9 months then the rice started spoiling after 12 hours. He said there is no way to eliminate the bacteria from the silicone gasket.
He suggested that after the “Warm” cycle, which is good for 12 hours, to remove the rice. The “Extend” cycle
is only good for another 12 hours at most. I have the same problem with a new Zojirushi Rice cooker. Talked to Zojirushi Tech person and they say that the silicone gasket got contaminated.

THIS^^^^^^. I have deleted my solution because it wasn't a long term solution even though Chloramine is still an issue. The problem about the gasket being contaminated seems to be the root cause. No amount of wiping will resolve it HOWEVER there is a way to mostly or completely eliminate the bacteria. I have done it and the rice holds and hasn't had a problem ever since, the cooker is back to normal. NO MORE STINKY RICE! Once you decontaminate the parts, I would recommend not storing it for more than a couple days on warm and or leave it in the cooker for too long because if you recontaminate the parts you'll have to do it over again.

You can service it IF you are comfortable with disassembly of electronics. You need to soak the pan in water with some bleach. You can then submerge and soak the parts in the pot and let them soak for a couple or few days, then make sure to rinse and soak for the day before reassembly. Removing the top half of the lid is the most difficult part, it is held on tightly and must be unsnapped.

Start at the rear sides and firmly but gently pry outward and slightly up to clear the cleats holding it on then work around to the front. The upper aluminum section is attached to the lid via bent tabs. CAREFULLY bend the tabs up to release it so you can remove the silicon gasket, you don't have to completely removed the aluminum part just loosen it so you can removed the gasket.

Soak the pan lid, the pan rim gasket, and steam vent gasket, and the other parts you can soak in the bleach water solution. Ge gentle with the aluminum tabs when reassembling, aluminum doesn't like to be bent multiple times. The outer cover start by hooking the front on the cleats then snap the rest using your hand to strike it as you work around towards the back. Sorry I didn't take step by step photos, look carefully at the lip around the top so you have an idea how the cover snaps on. The tabs for the lid are already bent upwards in the photos. Enjoy your nice fresh rice and don't reinfect it!

Hi, I am having the same issue and am wondering, what exactly do you mean when you soak the other parts? I see it's basically the entire lid component parts and the pan. Do you leave the base of the cooker alone? Thanks for the photos above, just wanted to make sure.

I had the same problem with a brand new one. Took it to Zojirushi and they said it's the casket. They had to change the casket formula due to EPA standards. My old one lasted for over 10 years then the warm function stated to deteriorate from 5 days to 1 day. They gave me another one but the same thing hapened even with a new Lid Gasket. So it's the seal that gets contaminated. They had no solution but to remove the rice before 24 hours and clean the Lid Gasket with vinegar or bleach and rinse well. Don't use the same sponge that you use for the counters. They don't make them like they use to. Wasted $300 for a 3 time use rice cooker. I had the same problem with a brand new one.
