Rice cookers are the ultimate lifesavers because you no longer have to worry about the rice getting mushy or undercooked rice. Similarly, the keep warm feature helps ensure that rice is warm once they are cooked and you don’t dish them out. However, before you invest in a rice cooker, you must know how long the keep warm feature works on the Zojirushi rice cooker. So, let’s find out more details!

How Long The Keep Warm Feature Works On Zojirushi Rice Cooker?

Before we check out how long it works, it’s important to understand what the feature is. The keep warm feature is responsible for keeping the rice warm whenever the rice is cooked and people don’t open the rice cooker to dish them out.

Some people even think if they can use the keep warm feature for more than a day or a few days, but it’s not the right approach. This is because keeping the rice in the rice cooker for days can result in bacterial growth and cause food poisoning.

For this reason, the keep warm feature is designed to warm up the rice at high enough temperatures to dismiss the chances of bacterial growth. However, the temperature must not be too high because the warm feature will end up burning or drying out the rice.

As far as Zojirushi rice cooker is concerned, its keep warm feature can work for up to twelve hours without compromising on the freshness of the rice (these twelve hours will ensure that rice doesn’t get spoiled).

In particular, Zojirushi rice cooker has also designed the extended keep warm feature for an even longer warming time. The keep warm button is placed on the control panel and you can simply use the reheat button for reheating your cooked rice.

At this point, we do want to add that the Zojirushi rice cooker takes a relatively longer time to cook rice because there is a microcomputer available which optimizes and controls the entire cooking process. As a result, rice will be yummier and it will be worth the time.

Keep Warm Feature Doesn’t Work

Now that we know that the keep warm feature works for over twelve hours once the cooking feature is ended. However, there are people who struggle with the keep warm feature on this rice cooker because it stops working.

Generally, when the water in the rice cooker is fully evaporated, the rice cooker will automatically switch on the keep warm feature. When it doesn’t kick in, there are the following troubleshooting methods that you should try!


In some cases, the keep warm feature doesn’t work because there is too much rice in the rice cooker. For instance, if the rice is more than minimum instructions, the keep warm feature won’t switch on.

The Inner Pot

When the rice isn’t fluffy, it could be why the keep warm feature isn’t switching on. For this purpose, you will need to take out the inner pot (do wear the hot pads) and check for deformities and dents. In case there are damages, the heating plate won’t settle properly and rice won’t cook, and the keep warm feature won’t kick in. That being said, get the deformities fixed to ensure cooking is being done properly.


The Zojirushi rice cookers are designed with a lithium battery and if the keep warm feature isn’t working, you should check the display. For instance, if the display has all zeros on it, the lithium battery has gone bad and it needs to be replaced. Once the battery is replaced, try using the keep warm feature and get it fixed.

Power Cord

If there are power interruptions to the rice cooker, it will hinder its ability to switch on the keep warm feature. For this reason, you should check the power cord and make sure it’s plugged into the functional power outlet.

In addition, the power outlet shouldn’t be more than 10 amps or 120 volts because anything higher will damage the cables and some features will be impacted. Anyhow, if the power cord is already damaged, replacing the power cord will be the ultimate solution.

The bottom line is that the Zojirushi rice cooker will enable the keep warm feature for over twelve hours and it will automatically tick off after these twelve hours. Also, we shared additional tips to fix the keep warm feature if it’s not working!
