Refrigerators

Open the freezer door of the refrigerator and if the sound stops after a short while, it might be due to blockage of ice in the fan rotation. You can switch off the refrigerator for a few hours for the ice to melt (please arrange your food in other cooling storage methods). Kindly contact Customer Service Centre for further assistance if the sound persists or if the refrigerator is not cold any more.

It takes time to cool or when there are alot of foods stored. It may take 4 ～ 24 hours to be fully cool after installing.
When using for the first time, it takes time to make ice because ice making starts after a full cooling. It may take more than 24 hours to make ice depending on the amount of food and its packaging.
Open/close the door quickly and/or minimize the number of times of opening and closing the door.
Allow space clearance between each food in the refrigerator.

If the sound is not continuous, it could be the fan motor starting sound. There will be a sound when the fan starts after freezer door is closed for a short while

There is no specific amount as to how much food you can store. However, please allow some space in front of the cold air vents of the refrigerator. Blocked air vents will reduce the cooling performance as air circulation is restricted. If you have many food in the fridge, please set the temperature lower

Please ensure that the water tank is pushed all the way behind the marking line. Please also check if water can be dispensed from the water dispenser or ice can be made. If the water level remains the same, it could be due to faulty water pump or printed circuit board. Please contact Hitachi Customer Service Center for repairs.

Yes. This is normal and will not affect the food quality in the fridge

Ensure enough ventilation space around the fridge body (top, behind, left and right). For different models, the required space may be different. Please refer to the user manual of the product for details.
Do not put any cover on top of the refrigerator, otherwise heat emitting effect drops resulting in poor performance and overheated compressor. The refrigerator surroundings may be warm due to gas piping running and heat emitting. It is not a malfunction.
To avoid extreme heat, place your refrigerator out of direct sunlight and away from heat sources such as cooking appliances

Please check temperature setting for Refrigerator.
Please deactivate energy saving setting.
Please ensure door is fully closed and not left open for long time.
Please check if there are many foods inside and if it is blocking the cold air blowing vents at the back.
Please check if there are any gaps on door edges.

Uniquely designed to maintain freshness and nutrients in fruits and vegetables, the Aero-Care Vegetable Compartment puts food under the power of a Platinum Catalyst, producing increased Carbon Dioxide to control respiration of fruits and vegetables and limiting the consumption of nutrients in the environment to prevent loss of freshness. In addition, the improved airtight seal of the compartment increases humidity, with the Humidity Control Unit also releasing excess moisture, so fruits and vegetables remain in optimal condition, further ensuring they retain their freshness and nutrients.

It is estimated at 2 minutes after pressing the 'Vacuum Compartment' button at the front panel of the refrigerator. Time varies depending on the amount of food stored.

Hitachi refrigerators with water dispenser series comes with a water tank that connects directly to the water dispenser. No troublesome plumbing is required and you can place your refrigerator anywhere in the home.

Only drinking water in the tank is recommended. Otherwise, the water tube may be clogged with juicy pulps or tea leaves.

Please check the temperature control dial and temperature setting. Ensure that it is not set at the lowest temperature setting. Please check if the food is touching or right in front of the air vent? If yes, please place the food further away from the air vent.

Ensure that the vacuum room door is not opened too frequently, as the hot air goes inside and thus causes condensation. Moisture in juicy food stored in the Vacuum Compartment will evaporate and cause dew condensation or frost in the Vacuum Compartment. Please wipe it off with a dry cloth

It might be due to insufficient water in the water tank, which causes the cubes to be smaller than usual and thus, cannot be crushed

This is due to the optimum humidity inside the vegetable compartment which keeps the vegetables fresh

The compartments are connected by cold air pathway where the air pressure will lead to the opening of the other door when one door closes hard. This is not malfunction

This is due to frosting, usually during the raining season or on high humid weather when the ambient temperature is high. It is not a malfunction. Please use a dry cloth to wipe off the water droplets and ensure that the surrounding of the fridge is well ventilated

In order to prevent the refrigerator from sweating and also to ventilate the heat, especially for new fridge, during the high speed operation of the compressor or when the doors are opened frequently, a lot of heat is generated and emitted from the side of the fridge body.The temperature can rise quite high, but it does not pose any safety or performance problems, but please avoid touching it

It is normal as water is produced within the refrigerator during defrosting process.

When the door is frequently opened, hot air goes inside and causes condensation. Please wipe it off with a dry cloth

a. Check temperature control dial and temperature settings.
b. Ensure that the refrigerator is not facing the sunlight directly.
c. Too much food storage could block the cool air flow circulation. Ensure that ventilation outlets are not blocked.
d. Check if the door is opened too frequently or for too long time.

a. Ensure that the ice maker function is activated and LED indicator lights are on.
b. Ensure that the water tank is filled with water.
c. Ensure that the water tank is fully inserted into the slot and pushed behind the indicated line.
d. Making ice for the first time will take a longer time (estimated 24 hours). Thereafter, it will take an estimated 2-3 hours to make 8 ice cubes.
e. Please check if ice compartment is full of ice. When the sensor detects that the ice tank is full, auto ice making process will stop.
Please do not put liquid such as juices, soft drinks, tea etc. other than plain water into the water tank, as it may damage the ice make

Please do not use any detergent or rough material to clean the door surface. Use only a soft cloth, rinse it with clean water, squeeze, and clean the surface of the door.

a. Check and ensure no powerful or quick cooling setting for vegetable compartment.
b. Keep the vegetables/fruits inside the vegetable drawer instead of the refrigerator compartment shelves.
c. Cold air is blown out from the air vents (normally located right back corner of vegetable drawer). If the item is placed just in front of the cold air vents and cold air blows onto it directly for a long time, it may freeze. Please keep the item in a container or move it away from the area

This indicates that the compartment is not in a vacuumed condition.
a. Check the vacuum setting on the control panel. Open one refrigerator door to check if the LED indicator (on control panel on the door surface) for Vacuum mode is turned on.
b. Ensure that nothing is trapped by the door of the vacuum compartment or rubber seal of the door and that the vacuum compartment door is tightly locked.
c. After the door of the vacuum compartment is locked, it takes about 3 minutes for the vacuum pump to run. Please check the hissing sound again after 3 minutes

Refrigerant (gas) pipes are running underneath at the side body. As such, some wave lines may be visible especially when compressor runs at high speed and the sides of the refrigerator is hot. This is normal and will not affect the performance of the refrigerator.

This is the sound caused by friction of parts due to temperature change

To ensure the coolant in the refrigerator stabilizes, please wait for 2 hours before you power it on

This is the operation sound of the inverter compressor of your fridge. The running speed of an inverter compressor varies and it is more energy efficient. To cool the new fridge faster, the compressor runs at high speed which will results in louder operation sound

The ice tray might not be turning completely, or remaining ice is stuck inside the ice tray. Please take out the ice tray and wash it clean. Insert it back and ensure that it is horizontal and level. Remember to turn the lever to lock the tray. Make a new batch of ice to test it

Changing the filter is not necessary. The filter eliminates bacteria & odors by its own catalyst. It is hassle-free and does not require any maintenance

Nano Titanium is a cutting-edge technology that uses a TiO2 catalyst to provide a powerful anti-bacterial and deodorizing effect.Nano Titanium particles are incredibly small (about 5nm). If you imagine the Earth's diameter is 1 meter, then 5nm would be the size of a golf ball compared to the Earth. The filter is packed with these minute particles to firmly catch and resolve bacteria, which are approximately 1000 times larger, mold and odors.

1. It might be due to the increase in temperature. Please check that all doors are closed tightly and there are no small gaps in between the door gaskets.
2. The internal water tube might be stuck which causes water overflow.
3. Compressor room is dusty and overheated.
