Low Medium High

Code Meaning Severity Common Symptom

DOR Door Open Alert Medium A regular soft beep cycles from the control panel, often paired with a flashing alarm icon. The alarm clears as soon as the door switch reports closed. View F0 BioFresh Compartment Sensor Fault Medium 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. View F1 Refrigerator Compartment Air Sensor Fault High The display still shows the target temperature, but the actual cabinet feels noticeably warm to the touch (sensor reading too cold) or items begin to freeze (sensor reading too warm). View F2 Refrigerator Evaporator Sensor Fault Medium Cabinet temperature is normal at first but slowly creeps upward as ice accumulates on the evaporator and progressively blocks airflow. View F5 Microprocessor / Control Board Fault High The control panel may go blank, show a jumbled string of characters, or display a temperature that does not change when buttons are pressed. View F6 Communication or Compressor Circuit Fault High Open the door and listen near the rear of the cabinet — a healthy Liebherr compressor produces a steady soft hum. Silence or repeated start-stop cycles indicate the inverter is not receiving consistent commands. View F7 Ambient Air Sensor Fault Low The anti-condensation door heaters are normally modulated based on ambient temperature; without the F7 sensor reading they default to a fixed setting that under-heats the door in humid environments. View F8 Compressor or Cooling System Abnormal High Listen near the rear of the cabinet — a healthy BluPerformance compressor produces a steady soft hum that cycles on and off through the day. Silence or unbroken continuous running both indicate an F8-class fault. View F9 Voltage or Power Supply Fault High The appliance powers off without warning when the supply voltage drops below the BluPerformance minimum or rises above the upper limit; it restarts when supply returns to range. View F10 Ice Maker System Fault Low The ice bin is empty and stays empty even after the normal ice-making cycle period. The cabinet continues to cool normally; only the ice maker is affected. View F11 Ice Maker Water Leak Medium Pull the ice bin and inspect the ice maker compartment — pooled water, water staining, or wet residue indicates a leak that has triggered F11. View F12 SuperCool Function Fault Medium Pressing the SuperCool button on the control panel produces no response, or the function activates briefly and cancels itself within a minute or two. View HF Post-Power-Cut Warm Alarm Medium A continuous or pulsing alarm tone announces that the unit experienced a temperature excursion while you were away. View
