38 error codes

CodeMeaning
03Communication error between the main control board (PCB) and the sub-board, display board, or motor control unit
highadvanced
5-UDThe 5 ud code, which is actually the 'SUD' error, indicates that the washer has detected an over-sudsing condition. The control board pauses the cycle to allow the foam to dissipate so the drain pump can function correctly.
moderateeasy
CECE stands for Current Error. The control board monitors the motor's electrical draw in real time, and when it detects a spike or short circuit beyond what the motor should be pulling, it shuts the cycle down immediately to protect the inverter components. Basically the machine's circuit breaker tripped itself on purpose.
highintermediate
CLChild Lock feature is active, disabling all control panel buttons except the Power button
lowbeginner
DEThe door interlock switch never got the 'door closed' signal. Either the latch hook didn't physically reach the switch, or the switch itself failed. The washer won't run until that signal gets confirmed, period.
moderateintermediate
DIAGGuide to accessing LG washer built-in service diagnostic mode and LG ThinQ Smart Diagnosis for component-level testing
lowadvanced
DLThe mechanical latch hooked in fine, but the electric solenoid inside the lock assembly either didn't activate or didn't send its locked confirmation signal back to the board. Two separate systems, and the second one failed.
moderateintermediate
DOOR-WONT-OPENThe door lock on your LG uses a wax motor or solenoid to physically bolt the door shut during operation. When it won't open, the machine either isn't sending the 'safe to open' signal, or the lock mechanism itself isn't releasing. Could be software like Child Lock, could be the wax motor not retracting, or could be residual water pressure telling the board to keep everything sealed.
moderateintermediate
ECLECL stands for Extended Cycle (Clean) reminder. The firmware hit a second threshold, typically around 60+ cycles since your last Tub Clean, because you dismissed the first TCL warning and kept washing. The machine's still fine, it's just really insisting you clean the tub now.
lowbeginner
FEThe control board's water level sensor caught water above the maximum fill threshold. That usually means the inlet valve isn't closing when it's told to, or the pressure switch is misreading an empty tub and calling for more water.
highintermediate
HUBHUB fires when the main control board loses communication with the display board. Basically the two brains of your washer stopped talking. Could be a loose connector on the wire harness, moisture damage on one of the boards, or an actual board failure. The washer won't run a cycle until that connection is restored.
lowbeginner
IEIE stands for Inlet Error. The washer opened its valves and waited for the pressure sensor to detect rising water. When that sensor didn't trip within about eight minutes, the control board threw the code and killed the cycle to protect the pump and drum.
moderateeasy
LDYour washer's drain timer expired before the tub was empty. Water is moving, just too slowly. Something's restricting the drain path, whether that's a clogged filter, a hose that's too long, or a pump that's starting to wear out.
moderateintermediate
LEThe motor is locked or unable to rotate, detected by the hall sensor reporting no rotor movement to the main control board
highintermediate
LEAKINGWater's escaping from somewhere in the sealed system. That could be a door seal, a hose connection, the pump housing, or in bad cases the outer tub itself. LG front loaders are pressurized during the wash cycle, so even a small gap will push water out consistently every single time you run it.
moderateintermediate
NOISEThe LG Direct Drive motor mounts directly to the rear tub with no belt or pulley in between. When the tub bearing wears out, you get metal-on-metal contact that creates a rumbling sound. The spider arm is the three-pronged aluminum piece connecting the drum to the shaft, and when it corrodes or cracks, the drum wobbles and causes grinding or banging.
moderateintermediate
NOSOUNDYour LG washer isn't throwing a real error code here, it's just not doing anything. Either the machine's not getting power to the right components, the cycle start conditions aren't met (door latch is the big one), or the drive motor has quit. No code, no noise, no movement.
lowintermediate
NOT-DRAININGAn LG washer not draining has standing water in the drum. LG front-loaders have an accessible drain pump filter behind a small door on the lower front panel. LG displays the OE error code when drainage fails.
moderatebeginner
NOT-FILLINGThe IE code fires when the washer's control board doesn't detect water entering the tub within its allowed time window, usually 8-10 minutes. The board monitors a pressure sensor or flow sensor, and when the expected signal never comes back, it kills the cycle and displays IE. Something's blocking water from getting in, or the valve can't open at all.
moderateintermediate
NOT-SPINNINGThe hall sensor tells the control board exactly where the rotor is at every millisecond of the spin cycle. When it fails, the board can't time the magnetic pulses correctly, so instead of smooth rotation you get a drum that just sits there vibrating or jerks and stops.
moderateintermediate
NOT-SPINNINGThe MEMS vibration sensor monitors how much the outer tub is physically shaking during the spin cycle. When it fails or starts reading garbage data, the washer can't confirm it's safe to ramp up to high-speed extraction. So it either loops endlessly trying to rebalance, or throws the UE code and gives up.
moderateeasy
OEThe washer cannot drain water within the allotted time window, typically 4-6 minutes for a full drain cycle
highintermediate
PEThe pressure sensor, or the air dome hose feeding it, isn't sending a valid water level signal to the main control board. The board has no idea how much water is in the tub, so it throws PE and shuts the cycle down before it can overfill or run dry.
moderateintermediate
PFPower Failure. The control board detected that incoming voltage dropped to zero during an active cycle. It saves the cycle position to memory and displays PF on the next power-up so you know the cycle was interrupted and didn't finish normally.

SMELLSDetergent residue, hair, and moisture have built up into a biofilm inside the tub, door boot seal fold, dispenser housing, and drain filter. LG's high-efficiency cycles use so little water that residue doesn't fully rinse away, and the trapped moisture creates a bacteria breeding ground that contaminates every load.

lowintermediate
SUDThe washer detected too many suds in the drum. This creates a suds lock condition where the drain pump can't move water because it's basically air-locked by foam, or the motor's sensing way too much resistance from all those bubbles trying to spin through.
lowbeginner
SUDThe SUD error fires when the washer's pressure sensor and optical foam detector pick up more air bubbles than the control board considers safe for normal operation. Basically the drum's full of foam instead of water, and the pump can't drain air. It's a protective pause, not a breakdown.
lowbeginner
TCLYour washer's internal firmware counter hit 30 completed wash cycles and flipped a maintenance flag. The display's basically saying 'hey, time to flush the drum.' No component failed, nothing's broken. It's a software reminder, same as an oil change light on your car.
lowbeginner
TEThe NTC thermistor is sending a resistance value outside the expected range, or it's completely open or shorted. The control board can't verify water temperature, so it shuts down the heating circuit and throws this code to stop you from running a cycle it can't monitor safely.
moderateintermediate
THINQ-HUBThinQ is LG's smart home platform built into the washer's control board. When you run Smart Diagnosis, the washer's processor encodes its internal sensor readings as audio tones and broadcasts them through a small front-panel speaker. The app decodes those tones and cross-references them with LG's server database to identify the exact fault code.
moderatebeginner
U5The drum's vibration sensor picked up too much wobble during spin and paused the cycle to protect the drum and cabinet. Same exact logic and sensor as UL, just displayed differently on certain LG model lines.
lowbeginner
UEUE stands for Unbalanced Error. The washer's got a sensor that monitors drum rotation speed and wobble during spin-up. When the drum starts pulling hard to one side and can't correct itself, the machine cuts power to the motor before that vibration gets bad enough to crack the outer tub or trash the bearings.
moderatebeginner
ULThe washer hit its vibration limit during spin because the laundry shifted off-center. It shuts down automatically to prevent damage to the drum bearings and suspension system.
lowbeginner
VIBRATINGAn LG washer vibrating excessively during spin has an imbalanced load, worn shock absorbers/suspension, leveling issue, or a vibration sensor fault. LG's TrueBalance anti-vibration system uses sensors to detect and compensate for imbalance.
moderatebeginner
VIBRATION-FAULTThe vibration sensor, also known as the MEMS sensor, is failing to accurately report tub movement to the control board, which prevents the washer from entering high-speed spin.
highintermediate
WONT-STARTThe control board is refusing to initiate the wash cycle because it's not getting a confirmed door-locked signal, there's no clean power reaching the board, or Child Lock is blocking all input. The board won't let anything spin until it gets the all-clear from those safety circuits.
