Liebherr Mediline Refrigerators
29 fault codes documented
Display shows A — Product sensor not activated
The letter 'A' on the display indicates that the optional product sensor, used for temperature measurement and recording, has not been activated within the appliance's settings.
AFr — Temperature around product sensor below 0°C
The display shows 'AFr', indicating that the temperature measured by the product sensor is below 0°C (32°F).
Door open alarm — Audible warning when door open
An audible warning signal sounds if the appliance door has been left open for longer than the preset delay time, typically 60 seconds by factory default. This helps prevent unwanted temperature fluctuations inside the unit.
E0, E1, E2, rE — Temperature sensor defective
The appliance's display shows E0, E1, E2, or rE, indicating that one or more internal temperature sensors are faulty and cannot provide accurate readings.
EE, EF — Electronic control system error
The appliance's display shows EE or EF, signaling a problem with the internal electronic control system that manages the Refrigerator's operations.
Etc (flashing) — Real time clock needs resetting
The display shows 'Etc' flashing, indicating that the appliance's internal real time clock needs to be reset. This often occurs after a power disruption or initial setup.
Etc, LED flashes, and Clock symbol – Real time clock needs reset
The display shows "Etc", a specific clock symbol flashes, and an LED flashes, indicating that the appliance's real-time clock needs to be reset. This often occurs after a power interruption.
Display shows F — Product sensor not connected or faulty
The letter 'F' on the display indicates that the optional product sensor is either not properly connected to the appliance or is experiencing a fault.
LED flashes and alarm symbol appears — Appliance fault
If the LED flashes and a general alarm symbol appears in the display, it indicates an unspecified fault with the appliance requiring attention.
HA / HF flashing — Alarm for temperature deviation or power failure
When 'HA' or 'HF' flashes on the display, it signals an alarm condition, such as the appliance's internal temperature being too high or too low, or a past power failure event.
HA, HF, and Power failure symbol flashes – Power cut or prolonged temperature out of range
The display shows "HA" (interior too warm/cold) or "HF" (power cut) and a power failure symbol flashes. This indicates either a power cut of some length or the interior temperature being outside the permissible range for a period.
HA/HF/Alarm bell symbol flashes — General alarm or power failure detected
HA/HF along with the alarm bell symbol flashing in the display indicates an active alarm condition, which can include a high/low temperature event or a past power failure.
HF, HA (flashing) — Power cut or temperature exceeded permissible range
The display shows 'HF' or 'HA' flashing, indicating that there has been a power cut of some length (HF), or the interior temperature was too warm (HA) or too cold (HF) during a specific period. These are stored alarm events.
HI — Interior temperature too high
The display shows 'HI', indicating that the temperature inside the appliance has risen above the permissible upper limit. An audible warning signal may sound, and the LED may flash.
HI, LED flashes, and audible warning – Interior temperature too high
The display shows "HI" and the LED flashes, indicating that the internal temperature of the appliance is too high. An audible warning signal will also sound (if not deactivated).
Ice layer in Refrigerator interior — Door left open or ice buildup
If the Refrigerator door has been left slightly open for an extended period, a layer of ice may form on the cooling plate and interior. This can impede proper cooling and requires manual defrost activation.
LED flashes (generic fault symbol) – Appliance fault detected
A general fault LED is flashing on the display, indicating that the appliance has detected an unspecified internal malfunction or error. There is no specific error code provided with this flash.
LED lights up and temperature display flashes – Door opened
When the appliance door is opened, the internal LED illuminates and the temperature display starts to flash. This is a normal operational indication that the door is open.
LO — Interior temperature too low
The display shows 'LO', indicating that the temperature inside the appliance has fallen below the permissible lower limit. An audible warning signal may sound, and the LED may flash.
LO, LED flashes, and audible warning – Interior temperature too low
The display shows "LO" and the LED flashes, indicating that the internal temperature of the appliance is too low. An audible warning signal will also sound (if not deactivated).
Appliance does not function – No power or inactive
The appliance is not operating or showing any signs of power. This indicates a complete lack of electrical supply or that it has been manually switched off.
Interior temperature is not low enough (too warm)
The Refrigerator compartment is not cooling adequately, and the temperature inside is higher than desired, potentially causing food spoilage.
Product sensor icon appears — Product sensor not activated
If the product sensor icon appears in the display, it means the product sensor has been installed but has not yet been activated within the appliance's electronic control system.
Product sensor icon with 'X' appears — Product sensor not connected or faulty
If the product sensor icon with an 'X' appears in the display, it indicates that the product sensor is either not properly connected to the appliance or is faulty and not functioning correctly.
The temperature is not low enough – Interior is too warm
The Refrigerator's interior temperature is higher than desired, meaning the cooling function is not sufficient. This can lead to spoilage of stored items.
btE – Back-up Battery error
An error has been detected with the appliance's back-up battery system. This battery supports functions like the power failure alarm during a mains power interruption.
btP, Power failure symbol, and audible warning – Power failure alarm (active)
The display shows "btP" and a power failure symbol, and an audible warning signal sounds, indicating that the appliance has experienced a power cut. The alarm will clear once mains voltage is restored.
dOr — Appliance door open too long (with flashing display and audible alarm)
The display shows 'dOr'. When the door is first opened, an LED lights up and the temperature display flashes. If the door remains open for more than 60 seconds, the LED flashes, the display shows 'dOr' alternately with the temperature, and an audible warning signal sounds.
dOr, LED flashes, and audible warning – Door open too long (over 60 seconds)
If the appliance door has been left open for more than 60 seconds, "dOr" and the temperature indication will flash alternately on the display, the LED will flash, and an audible warning signal will sound.
