Code Explanation
The FS error indicates a problem with the freezer
E FS temperature detection.
The rt error indicates a problem with the ambient
E rt temperature detection.
The rS error indicates a problem with the refrigerator
E rS side temperature detection (R1
Freezing Sensor Open or Short The dS error indicates
a problem with the defrost temperature detection.
Note: as a result the evaporator can be blocked with
ice from the moisture in the air.
r dS Refrigerator Sensor Open or Short
E HS Humidity Sensor Open or Short
E IS Icing Room Sensor Open or Short
The IS error indicates a problem with the ice maker
temperature detection. Note: as a result the ice
maker can be blocked as the cubes are no longer
E IS dispensed in the collector.
Error of flow meter or water input or low water
E gF pressure
After starting the Defrost Sensor does not become
8C or more after 80 min. The dH error indicates that
the temperature measured by the defrost sensor has
not raised over 5 degrees Celsius within 80 minutes
after the defrost has started. Note: as a result the
evaporator can be blocked with ice from the
F dH moisture in the air.
After starting the Defrost Sensor does not become
r dH 11C or more after 80 min
The It error indicates a problem with the ice maker
E It motor assemblies.
The FF error indicates a problem with the Freezer
Fan. Note: this fan circulates the cold air in the
freezer. A fan blockage increases the compressor
activity to keep the temperature at the requested
E FF level. Eventually the temperature inside will rise
The CF error indicates a problem with the Cooling
Fan. Note: this fan cools the condenser to allow
proper condensation of the refrigerant. A fan
blockage increases the compressor activity to keep
the temperature at the requested level. Eventually
E CF the temperature inside will rise
The rF error indicates a problem with the
Refrigerator Fan. Note: this fan circulates the cold air
in the refrigerator. A fan blockage increases the
compressor activity to keep the temperature at the
requested level. Eventually the temperature inside
E rF will rise
The IF error indicates a problem with the Ice maker
Fan. Note: this fan circulates the cold air from the
freezer to the ice maker. A feedback mechanism is
used to detect a fan blockage. A fan blockage affects
E IF the ice making process.
The CO error indicates a problem with the
communication between the Main PCB and the
E CO Display PCB.
The SS error indicates a problem with the water tank
E SS temperature detection.
When auto door motor does not move to maximum
E Ad position or home position within 5 seconds
E AS When auto door motor operation
