Liebherr Refrigerators F0 Error: BioFresh Compartment Sensor Fault
What Does Liebherr Refrigerator F0 Mean? The F0 fault code on a Liebherr refrigerator indicates a fault in the BioFresh compartment temperature sensor. BioFresh is Liebherr’s climate-controlled storage system for the most perishable foods — leafy greens, fresh fish, raw meat, soft cheeses — and it operates at a target temperature near freezing (typically around […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Maybe. The main refrigerator and freezer compartments continue operating normally. Only the BioFresh drawer is unsafe for sensitive storage until the sensor is repaired.
Can I reset the code?
Yes. A power cycle clears transient connector faults. F0 that returns within an hour points to a hardware-level sensor or harness failure that needs Factory-Authorized Service.
When to stop immediately?
Stop if you notice: F0 returns immediately after every power cycle, BioFresh drawer temperature drifts more than 5°F from the set point.
Symptoms You May Notice
BioFresh drawer contents spoiling faster than expected
Greens, fish, and meat in the BioFresh drawers begin to deteriorate sooner than usual because the drawer climate has drifted away from its target temperature.
F0 code shown on the display
The fault label appears in the temperature display area of the Liebherr control panel; on connected SmartDevice units the SmartDeviceBox app sends a notification.
Refrigerator main compartment continues to operate normally
The F0 fault is isolated to the BioFresh sensor — the main fridge compartment uses a different sensor (governed by F1) and stays at the correct temperature.
BioFresh humidity-control flap or fan behaves erratically
The BioFresh humidity system depends on the sensor reading to balance dry-storage and moist-storage zones; without a valid temperature, the humidity control runs in a default mode that can over- or under-humidify the drawers.
Possible Causes
BioFresh NTC sensor element failure
The thermistor inside the BioFresh sensor probe has failed open or short-circuit after years of high-humidity exposure inside the drawer area.
Requires ProfessionalBioFresh sensor harness disconnected or damaged
The sensor connector behind the BioFresh drawer assembly has worked loose during cleaning or a service visit, or a wire in the harness has chafed against sheet metal.
Requires ProfessionalMoisture intrusion into the sensor body
Condensate from the BioFresh humidity-control system has migrated into the sensor housing and bridged the probe contacts.
Requires ProfessionalSafe Checks You Can Do
-
1
Move BioFresh drawer contents to the main compartment
BioFresh contents are at risk because the drawer climate is no longer regulated. Move greens, soft fruit, and protein to the main refrigerator compartment until the sensor is repaired — they will keep safely there at the standard fridge temperature.
BioFresh drawers are designed for short-term storage of the most perishable items, so the move is reversible once the repair is done.

Power-cycle the refrigerator
Switch the unit off at the wall outlet or its dedicated breaker for 60 seconds, then restore power. The control board re-polls the sensor on startup; a transient connector glitch occasionally clears here.
Liebherr BluPerformance compressors include a built-in restart delay of about 4 minutes — do not be alarmed if cooling does not resume immediately after power restore.
When to Call a Professional
Contact a qualified technician if:
- F0 paired with any other F-code on the display
- Unit is more than 8 years old with no prior BioFresh service history
- BioFresh humidity control behavior has been unusual for several weeks
