LG Error Codes
What is your LG trying to tell you?
Every LG appliance prints a precise fault code when something goes wrong. Below is what that code on the display actually means — the cause behind the blink. We do not list DIY fixes, because on LG inverter platforms a wrong guess is what turns a $180 part into a $900 board.
Refrigerator
CH
Compressor
The compressor or its inverter drive has reported a fault and is not running at the expected rate.
Refrigerator
CO
Communication
The main control board and the display panel have lost communication with each other.
Refrigerator
DH
Defrost heater
The defrost heater circuit is open or shorted, so the evaporator can no longer be cleared of frost on schedule.
Refrigerator
DS
Defrost sensor
The thermistor watching defrost temperature is reading out of range.
Refrigerator
FF
Freezer fan
The evaporator fan inside the freezer compartment is jammed, disconnected, or not reporting its speed back to the board.
Refrigerator
rF
Fridge fan
The fresh-food compartment fan motor is not returning an RPM signal to the control.
Refrigerator
IF
Ice-room fan
The fan that cools the ice-making compartment is not reporting back to the board.
Refrigerator
FS
Freezer thermistor
The temperature sensor in the freezer is open, shorted, or reading outside the valid range.
Refrigerator
rS
Fridge thermistor
The temperature sensor in the fresh-food compartment is open, shorted, or out of range.
Refrigerator
IS
Ice level sensor
The ice-bucket level or fill sensor is reporting a fault to the control.
Refrigerator
It
Ice-room thermistor

Refrigerator
6Er
Open door
A door has been open or its switch has been stuck open longer than the alarm threshold.
Washer
IE
Inlet (no fill)
The washer did not reach the target water level in the expected time. The control is calling out either the supply, the inlet valve, or the pressure sensor.
Washer
OE
Outlet (no drain)
The washer did not drain to the empty pressure threshold in the expected time. Drain pump, hose, or filter restriction is the usual call-out.
Washer
UE
Unbalanced load
The drum could not balance the load well enough to ramp up to spin speed safely.
Washer
dE
Door lock
The door lock did not confirm it was engaged before the cycle could start.
Washer
LE
Motor lock
The motor hall sensor is reporting the drum is locked or stalling under load.
Washer
PE
Pressure sensor
The water-level pressure sensor is reporting values the control treats as out of range.
Washer
FE
Overflow
Water level rose above the safe overflow line — typically a stuck-open inlet valve or a faulty pressure sensor.
Washer
tE
Water temperature
The water temperature thermistor is reading open, shorted, or out of range.
Washer
CE
Motor current
The motor current sensor saw a current outside the expected envelope during a wash step.
Washer
AE
Auto-shutoff / leak
The internal safety system detected a leak or water where it should not be and shut the machine down.
Washer
Sud
Excess suds
The pressure trace looks like persistent foam — the cycle has been suspended for an automatic suds-rinse.
Washer
HE
Heater
The heater element circuit is reading open or shorted on the safety check.
Dryer
D80
Vent 80% blocked
The dryer measured airflow consistent with the lint duct being roughly 80% restricted.
Dryer
D90
Vent 90% blocked
Airflow has dropped to ~90% restriction — the cycle continues but is being throttled for safety.
Dryer
D95
Vent fully blocked
The exhaust is essentially closed. The dryer has paused to prevent overheating the cabinet.
Dryer
F1
Inlet thermistor
The thermistor at the heater inlet is reading open or shorted.
Dryer
F2
Outlet thermistor
The thermistor at the drum exhaust is reading open or shorted.
Dryer
tE1
Temperature 1
A thermistor on the heater side is reporting values the control considers a fault.
Dryer
tE2
Temperature 2
A thermistor on the exhaust side is reporting values the control considers a fault.
Dryer
dE
Door switch
The drum door is opening (or the switch is reading open) during the cycle.
Dryer
CE
Motor current
Motor current is outside the expected window. Common with a binding drum or a failing motor.
Dryer
nP
No power to heater
The heater is enabled but no current is being drawn — typically a broken element or open thermal fuse.
Dishwasher
IE
Inlet (no fill)
The dishwasher did not reach the target water level on the fill step. Supply, valve or float / pressure sensor.
Dishwasher
OE
Drain
Water was not pumped out within the expected drain time.
Dishwasher
LE
Leak detected
The leak sensor at the base of the tub has detected water on the pan.
Dishwasher
HE
Heater
The wash heater circuit is reading open or shorted.
Dishwasher
PE
Pressure sensor
The water-level pressure switch is sending values the control does not accept.
Dishwasher
tE
Thermistor
The wash-water temperature sensor is reading out of range.
Dishwasher
FE
Overfill
Water in the tub has climbed above the normal cycle level — usually a stuck inlet valve.
Dishwasher
nE
Vario motor
The motor that steers the spray-arm zones is not reporting its position to the control.
Dishwasher
AE
Auto-shutoff / leak
The safety system has detected a leak inside the chassis and has powered the machine down.
Dishwasher
bE
Communication
The main board and the display sub-board have lost talk-back between each other.
Dishwasher
CE
Wash motor
The wash motor RPM is not what the control expected for the step it is on.

Most LG fault codes look simple on the surface and hide a sealed-system, inverter, or compressor diagnosis underneath. We carry LG-specific parts in stock and read the code on the spot.
