How do I prepare the rice for cooking?

1. Measure rice correctly:

• Use the given measuring cup. 1 cup and make sure the rice level is equal to the cup edge. The cup measures approximately 180 ml.

• Note: Do not use a measuring cup from another source, as this may cause a difference in the rice amount measured.

2. Clean rice:

• Stir rice in clean water and quickly pour out the initial rinsing water. Rice absorbs the first water quickly, so drain it immediately to prevent a rice-bran smell.

• Repeat the procedure until the water becomes clear. Thoroughly stir the rice to prevent burning and smells from the bran.

• Note: Do not use a metal whisk or other metal tools when stirring rice in the inner pot as it may cause the fluorocarbon-resin coating to peel off.

3. Adjust the water level:

• Flatten out the surface of the rice. Put the pot on a smooth surface. Adjust the water level to suit the type, quantity of rice, and method of cooking. For example, to cook 4 cups of “White Rice”, fill to the “4” mark on the “WHITE” scale.

• Water levels are calculated roughly. You can adjust the amount of water as you desire.

• Note: Do not use hot water. It may make the rice wet. Using alkaline water may make rice too wet or turn it yellow. Cooking with hard water (like mineral water) may make rice crispy, dry, or hard; adjust water as appropriate. Reduce the water level for newly harvested rice. Adjust the water level as shown in the handbook (mostly on the rice package).


How do I prepare the cooker before starting to cook?

1. Add rice to the pot: Wipe off the water and foreign matter around and on the bottom of the inner pot. Note: Do not put the inner pot in the cooker when there is water or foreign matter around it to avoid malfunction or uneven rice cooking. Place the inner pot holder to be consistent with the position of the cooker.

2. Check the lid: Before cooking rice, remove the inner lid and make sure that there is no leftover rice or food. Do not forget to reattach the inner lid after checking.

3. Close the lid and reattach the steam cap: Slowly close the lid until the “click” noise is heard and then reattach the steam cap. The lid cannot be closed if the inner lid is not attached. Warning: Slowly close the lid until the “click” noise is heard, otherwise the cap will open automatically and may cause skin burn. Make sure that the steam cap is even, otherwise it may release hot water or steam.

4. Insert plug into the socket: The LCD will display the type of rice and method of cooking set and the current time. Note: Noise while working or sparks when plugging in might be caused by inverter charging, which is not considered a malfunction.


How do I cook rice (White, Jasmine, Japanese, Brown, Mixed, Sticky rice)?

Attention: Check the cooking method. Selecting another mode like “porridge” requires lots of water and may cause a hazard from the hot water released.

1. Press the ‘Menu’ button to move the indicator to the selected “Rice” type. Rapid light will blink only for White, Japanese, and Jasmine rice.

2. There are 2 types of cooking rice:

3. You will hear a melody (warning sound), and it will start cooking. The “Cook” or “Rapid” light will be on. The clock will show the time remaining for cooking.

Note: When cooking “Brown”, “Porridge”, or “Mix/Sticky” rice, the clock will show the current time and change to the remaining time a few minutes before the cooking is completed.

4. The melody (warning sound) will ring when the cooking is finished. The “Warm” light will turn on. The hour is shown as ‘h’.

5. Stir the rice after cooking.


What are the recommended cooking modes, amounts, and times for different types of rice?

Cooking mode Type of rice and recommended method Amount of rice (cup) Water level Indicator Cooking time (min)
Normal Cooking WHITE 1-10 WHITE 40-70
JASMINE 2-10 JASMINE 50-70
JAPANESE 1-10 JAPANESE 55-70
BROWN 2-7 BROWN 80-100
PORRIDGE/THICK 0.5-3 PORRIDGE/THICK 60-80

Rapid Cooking WHITE 1-10 WHITE 28-50
JASMINE 2-10 JASMINE 28-50
JAPANESE 1-10 JAPANESE 28-50

• “Rapid” takes a short time for cooking; therefore, the rice may be a little bit wet and hard.

• Seasoning for mixed rice should be placed on the top of the rice, without stirring.

• The amount of steam released varies depending on the cooking mode.

• Cooking time is based on a previous setting of time, temperature, etc.

• The time of cooking may be increased or suspended while cooking is in progress to adjust the rice to be tasty.

• There may be dew drops when you open the lid right after cooking. This is not considered a malfunction.

• After the cooking is finished, the middle of the rice might be compressed or the rice along the inner pot may be softer. This is because the heat is generated from electromagnetic waves inside the pot to ensure that the rice will be thoroughly cooked.

• If the rice is not stirred properly, it may absorb steam and become too glutinous or hard.


How do I use the Timer to set a finish time for cooking?

Pre-set time is the time to finish cooking. If the set time is close to the current time, the cooking will start immediately.

Note: Do not use Pre-set time for mixed rice (it may change the property of the ingredients or they may not be properly cooked). You can set the Pre-set time within a maximum of 12 hours.

Example: Set “Timer” to “7:30”

1. Check the current time; set the time if it’s not correct.

2. Press “Timer” after selecting “Cooking Mode”. The default factory time setting or the previous time set will appear.

3. Press ‘Hour’ or ‘Min’ to set the time to “7:30”. The time will change each time you press the button. ‘Hour’ increases by 1 hour, ‘Min’ increases by 1 minute. Press and hold for a rapid pace.

4. Press the ‘Cook’ button. The “peep peep” sound will alarm. The setting is completed. The “Cook (Reheat)” light will be off and the “Timer” light will be on. The time set will be recorded. Press the “OFF” button to cancel the programmed setting.

5. When the melody (warning sound) is on, the cooking is finished and the cooker will change to warming mode automatically. The “Warm” light will turn on.


How should I warm rice and what are the tips for keeping it tasty?

After cooking is finished, the cooker will automatically change to “Warm”. If the warming generates a smell or makes the rice sticky, follow this advice:

Type of rice Cooking mode Warming Advice
WHITE, JASMINE, JAPANNESE WHITE, JASMINE, JAPANNESE After cooking, it changes to Warm automatically. The Warm Mode with normal temperature can run for 24 hours, and the Warm mode with high temperature can run for 12 hours.
BROWN, RICE BERRY BROWN
STICKY, MIXED, WHITE BROWN (PORRIDGE) STICKY, MIXED RICE, PORRIDGE Do not Warm. (Warming may affect the quality, smell, or consistency of the rice).

To stop Warming, press [off] (The Warm light will be off).

Warming may accumulate moisture inside the lid, inner lid, or inner pot. This prevents the rice from getting dried and is not a malfunction.

Tip for Warming tasty rice:

• Stir rice occasionally while Warming.

• If the rice quantity is low, accumulate the rice in the middle of the pot to prevent it from getting dried or clumped.

• Use as little time for warming as possible. Do not warm rice for more than 24 hours (in case of warming with high temperature, time should not exceed 12 hours) as it may cause decolorizing and smell.

• Do not warm rice other than white rice (Brown, Porridge, Mixed/Sticky, Riceberry).

• Stir rice well before warming. Do not leave a rice scoop in the pot while warming and do not reheat cold rice.

• You can keep the rice tasty by wrapping it with plastic wrapping paper and warming it in a microwave oven.


How do I reheat rice in Warm mode?

What should I do if the rice is too soft, sticky, hard, or not cooked properly?

Amount of rice and adjustment of water level: Measure the rice using the provided cup. Make sure not to use more than the specified amount for each menu. If the rice is too soft, reduce the water level. If the rice is too hard, add more water.

Rinsing rice: Rinse rice until the water becomes clear. For rice that does not need to be cleaned, rinse it off if the water is not clear. Stir well to mix the rice and water.

The water for rinsing and cooking rice: Rinse rice with cool water. Do not use warm or hot water (Using warm water may make the rice sticky and wet). The rice may be too sticky and become yellow when using too-alkaline water. The rice may be crispy or hard when cooking with hard water (mineral water). Adjust the proper amount of water to suit each rice.

How to cook rice: In the case of programmed cooking, reduce the water level since the rice will absorb more moisture (to prevent the rice from being too soft).

Stirring rice: Stir the rice as soon as it is cooked. (This will evaporate extra water – this will prevent the rice from getting too sticky).

Bottom of inner pot and temperature sensor getting dirty: Remove foreign substances.

Cooker stops working while cooking rice: In case the cooker stops working while cooking is in progress due to the “Off” or “Warm” button being pressed, the plug being removed, or a blackout, the rice will not be cooked thoroughly.

Power supply: Using extension leads or plugging into the socket with other appliances may cause power failure and the rice may not be thoroughly cooked. Do not use extension leads and plug the cooker into an individual socket.


What should I do if the rice is burnt?

Cooking white rice at a high temperature may cause the rice to be brown. Other types of rice may be burnt or turn brown, which is not considered unusual.

Rinsing rice: For white rice, rinse until the water is clear. For rice that does not need to be cleaned, rinse it off if the water is not clear. Stir well to mix the rice and water.

Bottom of inner pot and temperature sensor getting dirty: Check for and remove any debris.


What should I do if boiled water is overflowing?

Amount of rice and adjustment of water level: Measure the rice using the provided cup.

Rinsing rice: For white rice, rinse until the water is clear. For un-waxed rice, rinse it off if the water is not clear. Stir well to mix the rice and water.

Blockage or dirty parts: Check how to remove blockage and foreign substances from the steam cap.

How to assemble the parts: Do not forget to attach the steam cap and inner lid before cooking.

How to check the cooking mode: Cooking in [Porridge] mode requires a lot of water. Hot water may overflow while cooking. Please be careful.


Why is the middle of the rice swelling or has a thin film?

IH heating and conducting heat for the inner pot may cause the middle part of the rice to swell or the part connected to the inner pot to look whiter – which is not considered unusual. A thin film is caused by starch from the rice grain which enhances the taste of the rice. Therefore, cooking rice at a high temperature will enhance better taste and is not considered an unusual aspect.


What should I do if mixed rice is not well cooked?

Adding seasoning and other ingredients: Add seasoning to the water. Adjust the water level and then stir to prevent the seasoning from settling down to the bottom of the pot. Add other ingredients to the rice after the water level is adjusted. Then mix the ingredients into the rice after the rice is cooked. (If seasoning or other ingredients settle on the bottom of the pot, it may affect heat induction).

Amount of seasoning and other ingredients: The proper amount of other ingredients is between 30-50% of the amount of the rice. Minimize the amount of other ingredients if such an ingredient is very oily. Reduce the amount of soy sauce.

How to cook rice: Cook immediately without programmed setting (programmed setting may affect the taste of ingredients or cause them to settle).


Why is the cooking duration long?

Immersing rice and steaming rice will be proceeded automatically compared to a cooker without a micro-computer system, and it uses a longer time – which is not considered an unusual aspect.

Quantity of rice and adjustment of water level: Measure the rice using the provided cup. Make sure not to use more than the specified amount for each menu.

Rinsing rice: For rice that does not need to be cleaned, rinse it off if the water is not clear. Stir well to mix the rice and water.

Cooker stops working while cooking rice: If the power supply fails while cooking, the duration will be extended accordingly to the time suspended.


Why is there an unusual odor from the rice and inner pot?

There might be a plastic or rubber smell during the first usage, which will fade after some time. Other odors may occur after cooking mixed rice or using the pot for other food – which is not considered an unusual aspect.

Cleaning rice: For white rice, clean the rice until the water is clear. For rice that does not need to be cleaned, rinse it off if the water is not clear. Stir well to mix the rice and water.

How to stir rice: Stir the rice as soon as it is cooked. (This will evaporate excessive water which prevents the rice from getting sticky).

How to cook rice: Do not wait before cooking the rice for too long a time during the summer.

Cooker stops working while cooking rice: In case the cooker stops working due to the “OFF” or “Warm” button being pushed, or the plug being removed, it may cause an odor.

Dirty parts: Remove dirt from the inner lid and steam cap.


Why is there an excessive amount of accumulated moisture?

Opening the cap right after the rice is cooked may show dew drops, which is not considered an unusual aspect.


Why does the rice have an unpleasant odor or become yellowish?

Warming rice for a long duration or repeatedly reheating may cause a smell and turn the rice to yellow – which is not considered an unusual aspect.

Warming rice: Do not put a rice scoop on the rice while warming. Do not warm cold rice.

Rinsing rice: For white rice, clean the rice until the water is clear. For rice that does not need to be cleaned, rinse it off if the water is not clear. Stir well to mix the rice and water.

How to stir rice: Stir the rice as soon as it is cooked. (This will evaporate excessive water which prevents the rice from getting sticky).

Dirty parts: Remove dirt from the inner lid and steam cap.


Why is the rice dried or sticky after warming?

Dried Rice:

Warming rice for a long time or repeatedly reheating may dry the rice – which is not considered an unusual aspect.

Quantity of warming rice: If the amount of rice to be warmed is little, accumulate the rice in the center of the pot before warming.

Dirty parts: Remove dirts from the sealer ring, temperature sensor, and the edge and bottom of the inner pot.

Part assembly: Do not forget to attach the steam cap and inner lid before cooking.

Dew drops / Sticky rice:

Warming may cause dew drop accumulation inside the lid, inner lid, or inner pot. This prevents the rice from getting dried; it is not the cooker’s malfunction.

How to stir rice: Stir the rice as soon as it is cooked. (This will evaporate extra water which prevents the rice from getting sticky and smelly).

Quantity of warming rice: If the amount of rice to be warmed is little, accumulate the rice in the center of the pot before warming.


Why can’t I warm the rice?

The alarm will ring and the rice cannot be warmed when it is still hot right after cooking and when it gets cooled down after warming.


Why is the rice not cooked within the set time?

The programmed cooking is set to cook rice within a specific time. The cooking will start close to the set time. The procedure takes time to complete, and sometimes, it may not finish within the set time. Make sure you check the current time and adjust it accordingly (the system clock contains 24 hours).


Why is there noise while working?

The following alarm/noises will occur while cooking, warming:

When plugging in While in use (cooking, warming etc.)
Operating noise (may cause sparks) / Charging noise of inverter circuit Frizzling noise / Releasing steam Wind noise / Cooler blower Operating noise / IH Heating system of inner pot Whistling noise

Why does the cooking time on the LCD change immediately or not show?

Change immediately: The cooking procedures will be adjusted automatically to enhance the rice taste. Hence, the time of cooking may be varied; it is not considered a malfunction.

Not show: The time of cooking will not be displayed when selecting other cooking modes than [White][Jasmine][Japanese]. The monitor will display the current time instead.


Why does the monitor display [H0] or [-:–], or the LCD screen turn off when unplugged?

Monitor displays [H0] or [-:–]: When the monitor displays H0, press the Off button and it will turn to -:–. Set the time to the current time.

The LCD screen will be off when the cooker is unplugged: In case of -:– or H0 displaying every time when plugging in or out, it means that the lithium battery inside the pot is flat. However, you can still cook and warm rice, but you cannot set the current time and set programmed cooking. You need to replace the lithium battery (which requires payment) from the dealer shop where you purchased the cooker. (The lithium battery is a special kind of battery which you cannot change yourself).


Why does the LCD screen display [C1], [C2], or [H1] – [H8]?

LCD screen displays [C1] or [C2]: This will appear and the cooker will be off when there is a power failure due to a connecting cord or the plug sharing a socket with other appliances. Do not use extension leads and do not share a socket with other electric appliances when cooking.

LCD screen displays [H1] – [H8]: The LCD screen does not show the current time even after pushing the [Off] button or the LCD screen displays the same content. Please bring the cooker for repair at the dealer shop where you purchased the cooker.


Why does the inner pot have uneven color or scratches?

Uneven color: After some time of usage, the fluorine coating color will fade, which will not affect the rice cooking or your health.

Scratches: To avoid damaging the fluorine coating, please follow these instructions:

[Do not use a metal scoop to stir or take food from the pot] [Do not wash cutlery or plates in the inner pot]

[Do not use vinegar with the inner pot] [Do not wash with scrubbing powder or brush]

[Use the provided rice scoop only]


What happens during a power failure while in use?

During cooking While warming
After the power comes back, the cooker continues cooking, but in case the power failure takes more than 30 minutes, the cooker will cancel the cooking. After the power comes back, the cooker continues warming, and the cooker will cancel the warming, depending on the rice temperature.

Why do steam leaks occur or is there noise interference?

Steam leaks from the place between the lid and cooker: The sealer ring or heating plate is deformed; please replace it with a new inner lid.

Noise interference into television and radio: The cooker may cause noise and wave interference with the TV; therefore, please place the cooker away (approximately 3 meters distance).
