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 E1 Door Sensor Malfunction Medium A continuous beep from the control panel announces door-open when the integrated cabinet panel is firmly seated. Pressing the alarm-mute button silences it briefly before it resumes. View E2 Secondary Zone Air Temperature Sensor Fault Medium A two-zone Liebherr wine cabinet shows two temperatures on the InfoLight display. With E2 active, one zone shows the correct value while the other shows dashes, a frozen reading, or alternates between E2 and a value. View E7 Defrost Heater Fault Medium Cabinet temperature is normal at first but slowly creeps upward as ice accumulates on the evaporator and progressively blocks airflow from the cabinet circulation fan. View E8 Defrost Timer Fault Medium E8 produces the same downstream symptom as E7: ice slowly accumulates on the evaporator and progressively blocks airflow because defrost cycles are not running on schedule. View F1 Temperature Sensor Fault High The display alternates between F1 and a temperature value, or shows dashes where the temperature should be. Long-term wine storage temperature is no longer guaranteed. View F8 Compressor or Refrigerant System Fault High Unlike F1 (which produces drift), F8 produces a steady warming trend because the cooling system itself is impaired. Cabinet temperature rises by 3–5°F per hour in a typical kitchen environment. View TEMP SWING Cabinet Temperature Instability Medium The cabinet target is set to a single value, but the actual reading swings across a wider range than the normal ±1°F tolerance — symptomatic of cooling system stress rather than a hard fault.
