CodeMeaningFirst checkProcedure
OEWMMeaningOutlet error: the machine could not empty the tub within the allowed drain window.User-fixableFirst checkDrain pump filter behind the bottom access flap, then the drain hose for a kink or a high loop.Open guide
IEWMMeaningInlet error: the tub did not reach its target water level within roughly eight minutes.User-fixableFirst checkBoth taps fully open, then the inlet screens inside the hose couplings at the machine.Open guide
UEWMMeaningUnbalanced load: the drum could not distribute the load evenly enough to spin.User-fixableFirst checkRedistribute the washing by hand, then confirm all four feet are locked and the machine does not rock.Open guide
dEWMMeaningDoor error: the control never saw the door lock confirm before the cycle started.User-fixableFirst checkPush the door firmly shut; check for laundry trapped in the seal and for a worn striker.Open guide
dE1WMMeaningDoor open error: the door switch reports the door as open during a cycle.User-fixableFirst checkHinge sag: lift the door slightly while closing. If it latches, the hinge needs shimming.Open guide
dE2WMMeaningDoor lock circuit error: the lock assembly is not responding to the control board.Service call likelyFirst checkUnplug for five minutes to reset, then inspect the lock connector for heat damage.Open guide
LEWMMeaningLocked motor error: the rotor could not turn, or the Hall sensor lost track of it.Service call likelyFirst checkEmpty the drum and spin it by hand. Grinding or a hard stop points at bearings or a trapped item.·
LE1WMMeaningDrive motor lock: reported on Direct Drive platforms when the stator draws lock current.Service call likelyFirst checkCheck the rotor bolt torque and look for rotor-magnet debris on the stator windings.·
FEWMMeaningOverfill error: water rose past the safe level, so the machine cut the fill and drained.Service call likelyFirst checkA valve stuck open. Close the taps: if water keeps entering, replace the inlet valve.·
PEWMMeaningPressure-sensor error: the water-level sensor reads outside its valid range.Service call likelyFirst checkThe clear pressure hose from tub to sensor: blocked with detergent sludge, split, or blown off.·
tEWMMeaningThermistor error: the water temperature sensor is open or shorted.Service call likelyFirst checkSensor connector at the heater block, usually low on the tub behind the rear panel.·
HEWMMeaningHeater error: the wash water did not warm at the expected rate.Service call likelyFirst checkHeater element resistance (expect roughly 20–30 Ω cold) and its earth connection.·
CEWMMeaningCurrent error: the motor drew overcurrent and the inverter shut it down.Service call likelyFirst checkOverloading is the common cause. Halve the load and retry before suspecting the board.·
PFWMMeaningPower failure: mains was interrupted mid-cycle. The machine resumes where it stopped.InformationalFirst checkPress Start to continue. Repeat occurrences point at the outlet, not the machine.·
AEWMMeaningAuto-off / leak error: the base tray float has detected water under the machine.Service call likelyFirst checkTip the machine back onto a towel: a wet base tray confirms the leak before you chase it.·
SEWMMeaningStator / Hall-sensor error: rotor position feedback is missing.Service call likelyFirst checkThe three-wire Hall connector on the stator; corrosion here is common in humid rooms.·
E6WMMeaningClutch error on top-load platforms: the drive cannot engage or disengage the basket.Service call likelyFirst checkRotate the agitator by hand; free spin in both directions means a failed clutch assembly.·
CLWMMeaningChild lock is active, not a fault. The panel ignores every button except power.InformationalFirst checkHold the two buttons marked with the padlock icon for three seconds to clear it.·
tCLWMMeaningTub Clean reminder: a maintenance prompt after roughly 30 cycles, not a fault.InformationalFirst checkRun the Tub Clean cycle empty, then leave the door ajar to dry the seal.·
d80DRMeaningExhaust duct is about 80% restricted: the dryer is warning, not stopping.User-fixableFirst checkLint screen first, then the flexible hose behind the machine: it crushes when pushed back.Open guide
d90DRMeaningExhaust duct is about 90% restricted. Drying times will have roughly doubled.User-fixableFirst checkDisconnect the hose and run a two-minute air-fry cycle: strong airflow means the blockage is downstream.Open guide
d95DRMeaningExhaust duct is about 95% restricted. Stop using the dryer: this is the fire-risk threshold.User-fixableFirst checkClear the full run from machine to wall cap, including the exterior flap.Open guide
tE1DRMeaningThermistor 1 error: the inlet/heater temperature sensor is out of range.Service call likelyFirst checkA restricted duct cooks this sensor. Clear airflow first, then measure the thermistor.·
tE2DRMeaningThermistor 2 error: the outlet/exhaust temperature sensor is open or shorted.Service call likelyFirst checkSensor connector at the blower housing; lint packs around it and pulls the terminal loose.·
tE4DRMeaningThermistor 4 error: the compressor-side sensor on heat-pump models is faulty.Service call likelyFirst checkClean the heat-exchanger fins behind the lower flap before condemning the sensor.·
dEDRMeaningDoor error: the drum door is not latching, or the switch has failed.User-fixableFirst checkListen for the click as the door closes; no click means the strike plate has worn.·
PSDRMeaningPower supply error: the dryer saw a mains surge or a phase problem.Service call likelyFirst checkRemove extension leads and plug directly into the wall on its own circuit.·
AEDRMeaningAssembly / EEPROM communication error between the control and display boards.Service call likelyFirst checkUnplug for ten minutes. If it returns immediately, the main board needs replacing.·
nPDRMeaningNo power to the heater leg: one side of the 240 V supply is missing.Service call likelyFirst checkA tripped half of a double-pole breaker: the drum turns, the air stays cold.·
F1DRMeaningComponent fault reported by the main board: usually a relay stuck closed.Service call likelyFirst checkDoes the drum heat when the cycle is off? That confirms a welded heater relay: unplug it now.·
OEDRMeaningCondensate drain error on condenser and heat-pump dryers: the pump cannot clear the tray.User-fixableFirst checkEmpty the water tank and clean its float; sludge on the float is the usual cause.·
Er FSRFMeaningFreezer sensor error: the freezer thermistor is open, shorted or disconnected.Service call likelyFirst checkIce build-up around the sensor pocket on the rear evaporator cover.·
Er rSRFMeaningFresh-food sensor error: the refrigerator compartment thermistor has failed.Service call likelyFirst checkSensor harness at the top-rear of the fresh-food liner, behind the light housing.·
Er dSRFMeaningDefrost sensor error: the sensor watching the evaporator is out of range.Service call likelyFirst checkPull the rear freezer panel: a solid block of ice on the evaporator confirms defrost failure.·
Er dHRFMeaningDefrost heater error: the evaporator did not warm during the defrost window.Service call likelyFirst checkHeater continuity behind the rear freezer panel, plus the thermal fuse clipped beside it.Open guide
Er FFRFMeaningFreezer fan error: the evaporator fan is not reaching its commanded speed.Service call likelyFirst checkIce around the fan blade jamming it. Melt it fully before you replace the motor.Open guide
Er IFRFMeaningIce-maker fan error: the fan feeding the ice compartment is blocked or failed.Service call likelyFirst checkRemove the ice bin and check for a frozen clump against the fan grille.·
Er CFRFMeaningCondenser fan error: the fan beside the compressor is stalled.Service call likelyFirst checkDust mat on the condenser coil at the back or underneath. Vacuum it and retest.·
Er CORFMeaningCommunication error between the main board and the door display.Service call likelyFirst checkThe harness in the top hinge: repeated door swings fatigue it until a strand breaks.·
Er ISRFMeaningIce-maker sensor error: the ice level or temperature sensor is faulty.Service call likelyFirst checkWipe the infrared emitter/receiver windows on the bin walls, frost blinds them.·
Er gFRFMeaningFlow-sensor error: the water line is not delivering the expected flow.User-fixableFirst checkSupply valve fully open and the filter within its 6-month life. Clogged filters trigger this first.·
Er 1FRFMeaningIce-maker fan / ice-room circulation error on InstaView platforms.Service call likelyFirst checkForce a defrost of the ice room, then confirm the duct flap moves freely.·
Er HSRFMeaningHumidity-sensor error: reported by models with a crisper humidity control.Service call likelyFirst checkThe sensor sits in the fresh-food ceiling module; condensation on it can cause false readings.·
OF FRFMeaningDemo / showroom mode is on: the lights and display work but nothing cools. Not a fault.InformationalFirst checkHold Ice Plus (or Refrigerator) and Freezer together for five seconds to exit demo mode.·
AEDWMeaningAqua error: the base float has detected a leak and the machine locked out.Service call likelyFirst checkTip the machine back 45°: any water that runs out confirms the base tray is wet.Open guide
IEDWMeaningInlet error: the tub did not fill to level in the allowed time.User-fixableFirst checkSupply tap under the sink, then the mesh filter inside the inlet valve coupling.·
OEDWMeaningDrain error: standing water remains at the end of the drain phase.User-fixableFirst checkThe sump filter stack, then the sink-waste spigot, new dishwashers often meet an unpunched knockout.·
FEDWMeaningOverfill error: water level exceeded the safe maximum.Service call likelyFirst checkInlet valve stuck open: close the tap and see whether the tub keeps filling.·
HEDWMeaningHeater error: the wash water did not reach temperature in time.Service call likelyFirst checkLimescale on the flow-through heater; in hard-water areas this is the first suspect.·
tEDWMeaningThermistor error: the temperature sensor reads outside its valid band.Service call likelyFirst checkSensor is on the sump housing; check its connector for water tracking.·
LEDWMeaningMotor lock error: the wash pump cannot turn.Service call likelyFirst checkGlass shards or a fruit stone in the sump jamming the impeller.·
nEDWMeaningVario / diverter motor error: the valve that alternates spray arms is stuck.Service call likelyFirst checkListen during fill: a healthy diverter clicks as it steps between positions.·
bEDWMeaningButton error: a touch key is reading as held down.User-fixableFirst checkDry the control panel thoroughly; steam behind the membrane causes phantom presses.·
CEDWMeaningCommunication or overcurrent error on the wash-motor circuit.Service call likelyFirst checkUnplug for five minutes; if it reappears within one cycle, the board is the suspect.·
CH01ACMeaningIndoor room-temperature sensor is open or shorted.Service call likelyFirst checkSensor clip behind the front grille; it pops out during filter cleaning and gets left loose.·
CH02ACMeaningIndoor pipe inlet sensor fault.Service call likelyFirst checkThe sensor bulb should be clipped tight to the copper, not dangling in air.·
CH04ACMeaningDrain pump / float switch tripped: condensate is not leaving the indoor unit.User-fixableFirst checkBlow through the condensate line outdoors; biofilm blocks it every couple of seasons.·
CH05ACMeaningCommunication error between indoor and outdoor units.Service call likelyFirst checkInterconnect terminal block at the outdoor unit, loose or corroded wire 3 is the classic cause.Open guide
CH06ACMeaningIndoor pipe outlet sensor fault.Service call likelyFirst checkCompare both pipe sensors cold: matching resistance rules the pair out.·
CH09ACMeaningIndoor unit EEPROM error.Service call likelyFirst checkPower-cycle at the isolator for two minutes. Persisting means the indoor PCB needs replacing.·
CH10ACMeaningIndoor BLDC fan motor locked.Service call likelyFirst checkSpin the barrel fan by hand: dust cake on the blades adds enough drag to trip this.·
CH21ACMeaningOutdoor IPM fault: inverter power module overcurrent.Service call likelyFirst checkClear the condenser coil and confirm the outdoor fan spins freely before any board work.·
CH22ACMeaningOutdoor high current (CT2): the compressor is drawing too much.Service call likelyFirst checkRestricted airflow or overcharge. Check the coil, the fan and the ambient temperature first.·
CH23ACMeaningDC link low voltage at the outdoor inverter.Service call likelyFirst checkSupply voltage under load at the outdoor terminal, long thin runs sag here.·
CH26ACMeaningDC compressor position error: the compressor will not start.Service call likelyFirst checkCompressor winding resistance and the three-phase plug seating at the inverter.·
CH32ACMeaningDischarge pipe temperature too high.Service call likelyFirst checkUsually undercharge or a restriction. Do not top up refrigerant without finding the leak.·
CH41ACMeaningCompressor discharge temperature sensor fault.Service call likelyFirst checkSensor pocket on the discharge line: heat cycling works the clip loose.·
CH44ACMeaningOutdoor air temperature sensor fault.Service call likelyFirst checkSensor sits behind the outdoor grille; insects nest around it and crush the lead.·
CH53ACMeaningCommunication error, indoor unit to outdoor unit signal line.Service call likelyFirst checkInterconnect cable run: staples through the sheath and shared conduit with mains both cause this.Open guide
CH60ACMeaningOutdoor unit EEPROM error.Service call likelyFirst checkIsolate for five minutes. If it returns, the outdoor PCB has lost its calibration data.·
F1OVMeaningOven temperature sensor open: the control has lost its feedback.Service call likelyFirst checkSensor resistance at room temperature: roughly 1,080 Ω is healthy on most LG ovens.·
F3OVMeaningOven temperature sensor shorted.Service call likelyFirst checkCheck where the sensor lead passes the liner: a pinched lead shorts against the case.·
F9OVMeaningOven did not reach temperature: heating or ignition failure.Service call likelyFirst checkGas models: watch the igniter glow. If it glows but never lights, the igniter is weak.·
F11OVMeaningStuck key: the touch panel reports a button held down.User-fixableFirst checkClean around every key and let the panel cool; heat swell from the door vent causes it.·
LOCOVMeaningControl lock is engaged, not a fault.InformationalFirst checkHold the Lock (or Clear/Off) key for three seconds to release.·
F1MWMeaningThermistor / sensor error on the cavity temperature probe.Service call likelyFirst checkLet it cool fully: an over-temperature trip after long use reads the same way.·
F3MWMeaningHumidity sensor error on sensor-cook models.Service call likelyFirst checkClean the sensor vent inside the cavity ceiling; grease film blinds it.·
F5MWMeaningDoor sensing error: the interlock switches disagree about the door state.Service call likelyFirst checkDoor alignment. Never defeat an interlock: the monitor switch will blow the line fuse by design.·
SEMWMeaningStuck key error on the membrane keypad.User-fixableFirst checkUnplug for two minutes, then press each key once to find the one that does not click back.·
