Maintenance
Cleaning (Clean the refrigerator once a month)
1. Unplug the refrigerator.
2. Take out all the food.
3. Wipe the refrigerator clean.
● Wiping off smudges immediately is highly recommended. It is also recommended to
clean the areas of the refrigerator which are not easily accessible, once a year.
● Use soft cloth with lukewarm water to wipe off smudges. If it is difficult to remove
smudges, use diluted, pH-balanced washing liquid.
● Neatly clean the door gasket, because it gets dirty easily.
4. If any droplets remain on the surface of the parts, wipe them.
5. Return all parts to their original locations.
6. Check and clean the power plug, cord and outlet.
7. Plug the power cord into the outlet.
Notice
● Even if the power plug is plugged in immediately after being unplugged,
the compressor will not run for 10 minutes. However, if the inside is not cold,
it will start running in approximately 30 seconds.
Troubleshooting
Before you call for service, please check the following items:
The refrigerator does not get cold at all.
The refrigerator does
not get cold enough.
Food in the refrigerator
compartment freezes.
Outside
Dew appears.
Inside
The inside is smelling.
The refrigerator is noisy.
The Control Panel does not respond:
The Control Panel
does not respond:
The Control Panel is unlit.
This is not a malfunction of the refrigerator.
The surface of the
refrigerator is hot.
If a door is shut,
other doors may open.
Does the refrigerator make any
abnormal noises (sound)?
Annoying sound is generated
by the refrigerator.
Operation sound lasts long.
Operation sound sometimes
becomes louder.
There are waving and/or distortions
on the door surface, the side and
the top surface of the refrigerator.
● Is the refrigerator plugged in properly?
● Is the refrigerator placed in the direct sunlight?
● Is the temperature set to "Cold"?
● Is the food stored too much?
● Is the door being slightly opened ?
● Is the temperature set to "Coldest"?
● Do you place food with moisture or vegetables nearby the cold air vent? It will be frozen if it is placed nearby the cold air vent.
● When the ambient humidity is too high, the door gasket may have dew. Please wipe it up with dry cloth.
Please wipe it off with dry cloth and please check the details below.
● Is the door closed firmly?
● Is the door being opened and closed too frequently or opened for a long time?
● Do you store food with odor without wrapping it?
● Make sure the refrigerator is installed firmly.
● Is "Child Lock" selected by using the lock function on the panel for operation?
● Is Refrigerator the compartment Door open? Operate after closing it.
● Is there water or dirt on the Control Panel?
● Are you wearing gloves or applying a plaster? Touch directly with your finger.
● Are you touching a next button? Touch only one button at a time
● Approximately 30 seconds after the end of operation, Indicator LED become unlit (Except ECO and Dual Fan LED become dim ).
● The refrigerator is equipped with the dew prevention and heat radiation tubes.
The back and side plates may be heated especially when starting up or if the door is frequently opened and closed.
● The two compartments are connected with an air duct. When closing one of the doors, the door may be opened by
the air pressure through the duct. This is a normal phenomenon.
● The sound like water flowing and boiling water is the sound of the cooling liquid (refrigerant).
● A creaking sound comes from the storage compartment. It is the sound caused by friction of the parts due to temperature change.
● You may feel that the operation sound is larger because the comppressor operates in high-speed under the following conditions: the refrigerator
does not cool fully on the occasion such as using it for the first time, opening/closing the door frequently, the surrounding temperature is high.
The sound becomes more quiet after cooling fully.
The compressor operates at low speed at night, for long vacations or absences, potentially creating large vibrations.
● It is because the compressor operates in low-speed for conserving energy.
● It is because the system changes the operating power of the refrigerator according to the temperature change.
● Slight waving and/or distortions are generated in the manufacturing process of the refrigerator.
They may be conspicuous according to the position of the light source and/or the brightness etc.,
but there is no problem with the performance.
Caution
● Do not do the following, since parts and paint may be damaged.
1. Do not splash water to the doors and refrigerator body.
● It may cause electric shock or a fire.
● It may cause refrigerant leakage because of pipe rust.
2. Do not use following: Polishing powder, soap powder, oil,
boiling water, brush, acid, benzene, thinner, alcohol and
alkaline detergent, etc.
● It may cause damaged door surface.
● It may cause cracked plastic parts.
3. If the cooking oil smears on the refrigerator, please wipe if off
immediately. The plastic parts might be cracked.
■ When replacing lamps (LED) is required.
Please contact your dealer or Hitachi Service Center.
● Check the fuse box for blown fuse or tripped circuit breaker.
● Is the refrigerator placed near heat sources?
● Has anything hot been placed in the refrigerator?
● Is the door being opened and closed too frequently?
● Is it too humid outside?
● Is the refrigerator touching the wall?
