Liebherr's unique technologies
Understanding Liebherr's unique technologies will help you maintain your refrigerator correctly and identify faults early:
BioFresh — keeping fresh
BioFresh technology maintains the temperature just above 0°C with an optimal humidity level. Fruit and vegetables stay fresh for up to three times longer than in a conventional refrigerator. If the BioFresh compartment is not cooling properly, check that the drawers are closed tightly and that the ventilation openings are not blocked.
NoFrost — no frost
The NoFrost system prevents ice from building up in the freezer by using a fan to circulate cold air. If ice appears on the sides, it is a sign of a malfunction in the defrost system or the rubber seals.
DuoCooling — Double Cooling
Two separate cooling circuits for the refrigerator and freezer compartments. The advantage: no odors transfer between the compartments and the food does not dry out. A malfunction in one circuit does not affect the other.
MagicEye — Touch Monitor
Digital operating interface with touch keys. Error codes appear on this display. If the display is unresponsive, try cleaning it with a dry cloth. A persistent display malfunction requires a technician.
Common faults and solutions
According to the Plrom team of technicians, these are the faults they frequently encounter with Liebherr refrigerators:
| fault | signs | possible reasons | solution |
|---|---|---|---|
| The refrigerator is not cooling. | High temperature in the refrigerator compartment | Thermostat, gas leak, compressor | Thermostat check, call a technician |
| Ice accumulation | Thick layer of ice on the sides | Defrost system is faulty, rubber seals are worn out. | Sealing test, contacting a technician |
| Unusual noise | A loud metallic noise or buzzing sound | Fan, compressor, refrigerator unbalanced | Balancing the refrigerator, calling a technician |
| Water leak | Water on the floor under the refrigerator | Clogged drain, rubber bands | Drain cleaning, sealing test |
| The freezer is not freezing. | Unfrozen food, high temperature | Fan, sensor, gas leak | Contacting a technician |
| Monitor is unresponsive | The touch keys are not working. | Control card, humidity, short | Dry cleaning, reset, technician |
⚠️ Important: Using generic parts may impair the performance of the refrigerator and cause additional malfunctions. Plrom uses only original Liebherr parts, with a warranty of 3 to 12 months. For information on repair services.
Tests you can do yourself
Before you call a technician, try the following tests. They are simple and may save you time and money:
1. Check the thermostat
Make sure the thermostat is set to the correct level. The recommended temperature for the food compartment is 3-4 degrees and for the freezer -18 degrees. Check that the "Vacation" or "Eco" button, which reduces cooling, has not been accidentally pressed.
2. Test the rubber seals
Worn rubber seals are a common cause of reduced cooling. Do a simple test: insert a sheet of paper between the door and frame and close it. If the sheet comes off easily, the rubber seals need to be replaced. Clean the rubber seals with lukewarm water and mild soap.
3. Airflow test
An overcrowded refrigerator prevents proper air circulation. Be sure to leave space between products. Check that the interior ventilation openings are not blocked. In Liebherr refrigerators, the ventilation openings are usually located on the back wall.
4. Cleaning the drainage ditch
There is a small drain hole at the back of the refrigerator compartment that drains water from the defrosting process. A blockage in the drain causes water to build up and leak. Clean gently with a wooden toothpick or lukewarm water.
5. Cleaning the condenser (coils)
The coils on the back of the refrigerator are responsible for heat dissipation. Dust and dirt interfere with the process and force the compressor to work harder. Clean with a vacuum cleaner or soft brush once every six months.
6. Resetting the refrigerator
Sometimes an error code appears due to a temporary malfunction. Unplug the refrigerator for 10 minutes and plug it back in. If the code returns, the problem requires professional attention.
Recommended maintenance schedule
Preventive maintenance is the key to a refrigerator that will work for many years without problems. Here is the recommended schedule:
| frequency | פעולה | explanation |
|---|---|---|
| weekly | Temperature test | Make sure the display shows 3-4°C in the refrigerator and minus 18°C in the freezer. |
| Monthly | Cleaning rubber gaskets | Damp cloth with mild soap, dry completely |
| Quarterly | Drainage canal inspection | Make sure the drain is open and there is no dirt buildup. |
| Semi-annual | Coil cleaning (condenser) | Vacuum cleaner or soft brush for dust removal |
| annual | Professional inspection | A certified Liebherr technician checks all systems |
It is recommended to have a professional inspection done once a year. The technician will check the compressor, gas level, defrost system, and control panel. Early detection of problems saves expensive repairs in the future.
When is it necessary to call a technician?
There are situations where home testing is not enough. Contact a certified Liebherr technician immediately in the following cases:
- Error code (F0-F7) that does not disappear after reset
- The refrigerator does not cool at all even though it is plugged in.
- Unusual noise from the compressor — clicking, high-pitched sounds, or loud humming
- Burning smell or smoke from the refrigerator
- The stopper pops up every time the refrigerator is turned on.
- Constant water leak under the refrigerator
- Digital display not responding after cleaning and resetting
- Freezing products in the refrigerator compartment (not in the freezer)
Most repairs are carried out at the customer's home within one to two hours. The cost of an inspection visit is 390 NIS, and the technician will provide an accurate quote before carrying out the repair. In complex cases, the technician will recommend taking the refrigerator to a professional laboratory.
