This Liebherr refrigerator error codes guide explains what the letters and numbers on your display actually mean, so you can tell a quick self-fix from a fault that needs a technician. Liebherr units use a combination of sensor fault codes (F-series), temperature alarms (E/HI/LO), and door alarms (DOR), shown on the control panel.
Sensor and control faults (F-series)
- F0 – BioFresh air sensor fault.
- F1 – fridge compartment sensor failed.
- F2 – evaporator sensor fault; the unit may ice up or stop cooling.
- F3 / F4 – freezer air / evaporator sensor faults.
- F5 – microprocessor or control-board fault.
These are genuine hardware faults; sensor and board replacement is a technician job, not a reset.
Alarms you can often clear
- DOR – door left open; close it and the alarm clears.
- E0 / HI – compartment too warm (after a long door-open, power cut, or large warm load); often recovers on its own.
- LO – compartment too cold for the setting.
What to do first
- Write down the exact code shown.
- For DOR or a temperature alarm, close the door, check the load and setting, and wait for recovery.
- For any F-code, do not keep cycling power – note it and arrange diagnosis.
For individual codes with symptoms and causes, browse our refrigerator error code archive. If the fridge is also warm, our not-cooling troubleshooting guide pairs well with this list.
When to call a technician
F-series sensor and board faults, plus any persistent temperature alarm with correct settings, warrant a certified visit before food is at risk. You can schedule service, and you can confirm the code set for your exact model on the manufacturer’s site at home.liebherr.com.

When to call a Liebherr technician
It is worth being clear about the line between sensible owner maintenance and work that belongs with a professional. Routine cleaning, simple resets, filter changes, and basic setup are well within reach for most owners and are exactly where this guide focuses. Anything involving the sealed refrigeration system, a temperature or evaporator sensor, the control board, or removing a built-in column from its niche is different: those repairs carry real performance and warranty implications and should be handled by a certified technician with the correct tools and genuine Liebherr parts. A Liebherr appliance is a long-term, premium investment built to run for many years, so it is almost always worth maintaining and repairing properly rather than letting a small fault compound. When in doubt, a quick diagnostic visit removes the guesswork, protects the appliance, and gives you a clear, written quote before any work begins so there are never surprises.
