LG washing machine error codes are built-in diagnostics that identify issues like drainage faults, heating errors, or motor problems.
Modern washing machines contain sensors monitoring water levels, temperatures, motor performance, door locks, and drainage throughout each wash cycle. When these sensors detect abnormal conditions—water not draining within expected time, temperatures not reaching set points, or the drum failing to spin—the machine’s control board generates specific error codes displayed on the digital panel.
These coded diagnostic systems exist because they dramatically simplify fault-finding. Without codes, you’d need to guess whether poor washing results stem from drainage problems, heating failures, or mechanical issues. Error codes eliminate guesswork, pinpointing the specific system experiencing problems and guiding appropriate troubleshooting.
Codes appear on your machine’s display panel, typically as two letters (OE, IE, UE, DE, LE, FE, TE, HE, SE, CE, CL) sometimes with accompanying numbers. The machine usually pauses the cycle when displaying error codes, preventing operation until the fault is resolved. Some codes cause complete stops, while others allow manual draining or door unlocking for load removal.
Recording the exact code before resetting matters significantly. Error codes provide engineers with immediate diagnostic information when you call for repairs. Knowing you have an “OE” error rather than vaguely reporting “it won’t drain” helps engineers bring appropriate parts and tools, potentially resolving problems in a single visit. Take a photo of the error code display—this documentation is invaluable when describing problems to repair services.
| Error Code | Meaning | Quick Action |
| OE | Drain Error | Check drain hose and clean filter |
| IE | Water Inlet Error | Check water supply and inlet filters |
| UE | Unbalanced Load | Redistribute clothes evenly |
| dE | Door Error | Check door seal and latch |
| FE | Overfill Error | Turn off water supply, call technician |
| TE/HE | Temperature/Heater Error | Call technician |
| CL | Child Lock Active | Hold Temperature + Rinse buttons for 3s |
| SE | Motor Error | Call technician |
| CE | Electrical Error | Unplug machine, call technician |
OE means the washer cannot drain properly, usually due to a blocked filter, hose obstruction, or pump issue.
The OE code (sometimes displayed as 0E) appears when the machine cannot empty water within the expected timeframe—typically 5-8 minutes. Sensors detect that water level isn’t dropping despite the drain pump running, triggering the error and stopping the cycle to prevent overflow or water damage.
Common causes and solutions:
Blocked pump filter: This is the most frequent cause and easiest to resolve. The pump filter catches debris—coins, buttons, lint, small items from pockets—preventing them from entering the pump. Locate the filter access panel at the front bottom of your machine (usually on the right side). Place towels underneath as residual water will spill when opened. Unscrew the filter slowly, remove trapped debris, rinse thoroughly, and replace securely. Run a rinse cycle to test.
Kinked or blocked drain hose: Check the large corrugated hose running from your machine to the standpipe or sink. Ensure it isn’t kinked, crushed behind the machine, or positioned too high. The hose outlet shouldn’t be more than 100cm above floor level. Disconnect the hose and check for obstructions—lint buildup often restricts flow without completely blocking drainage.
Pump failure: If the filter is clean and hose is clear but OE persists, the drain pump itself may have failed. Listen when the error occurs—a working pump makes a distinct humming sound. Complete silence suggests electrical failure; humming without drainage indicates mechanical seizure or impeller damage. Pump replacement requires professional repair.
London’s hard water exacerbates drainage problems by creating limescale deposits in pumps and hoses over time, gradually reducing flow capacity until blockages occur.
IE indicates a water supply problem caused by low pressure, closed taps, or blocked inlet filters.
The IE code (sometimes 1E) appears when the machine cannot fill with water within 4 minutes of starting a cycle. This timeout prevents the machine running indefinitely trying to fill, protecting against flooding from faulty valves and alerting you to supply problems.
Troubleshooting steps:
Check water supply taps: This sounds obvious but accounts for many IE errors. Ensure both hot and cold inlet taps behind the machine are fully open. If you’ve recently moved the machine or performed plumbing work, taps may have been partially closed.
Clean inlet mesh filters: Small mesh filters inside the inlet hose connections prevent debris entering the machine. Over time, sediment and limescale accumulate, restricting flow. Turn off water supply, disconnect inlet hoses, and locate the small plastic filters inside the hose connectors. Remove carefully with pliers, rinse thoroughly under running water, and replace. London’s hard water causes significant filter clogging—inspect these every 6 months.
Water pressure issues: Your machine requires minimum 20 PSI (1.4 bar) water pressure. Low building pressure, particularly in upper-floor London flats or during peak usage times, can trigger IE errors. If neighbouring properties experience similar issues, contact your water supplier about pressure problems.
Faulty inlet valve: If taps are open, filters are clean, and pressure is adequate, the inlet valve solenoid may have failed electrically or become mechanically stuck. This requires professional replacement.
UE signals an unbalanced load that prevents the machine from spinning safely.
Modern washing machines spin at high speeds—1200-1400 RPM for LG models—generating significant centrifugal forces. If laundry distributes unevenly around the drum, the resulting imbalance causes dangerous vibration and mechanical stress. The UE code protects your machine by preventing high-speed spinning when loads are unbalanced.
Resolving UE errors:
Redistribute laundry: Open the machine and manually rearrange items evenly around the drum. Heavy items bunched on one side create imbalance. Spread everything out, close the door, and restart the cycle.
Avoid overloading: Cramming too much into the drum prevents proper distribution during spin. Follow capacity guidelines—typically 8-9kg for large LG machines, 6-7kg for compact models. Measure by weight or fill only to 3/4 capacity by volume.
Don’t wash single heavy items: A single bath mat, duvet, or thick blanket cannot balance properly. Add towels or other items to create distributed weight.
Level the machine: Persistent UE errors despite proper loading suggest the machine isn’t level. Use a spirit level across the top. Adjust the front feet (usually screw-threaded) until the machine sits perfectly level front-to-back and side-to-side. Unlevel machines cannot distribute loads properly.
Check floor surface: Machines on uneven floors or soft surfaces (old floorboards, vinyl flooring) may rock during spin, triggering UE errors. Ensure firm, level installation surface.
DE means the door is not properly closed or the locking mechanism is faulty.
The door lock is a critical safety feature—it prevents opening during operation when the drum contains water or spins at high speed. The DE code indicates the control board cannot verify the door is securely locked, preventing cycle start or stopping mid-cycle.
Common fixes:
Inspect door closure: Ensure the door closes fully with a distinct click. Wipe the door seal area—detergent buildup or debris can prevent proper seating. Check nothing is trapped between the door and seal.
Remove trapped fabric: Small items—socks, underwear edges—can lodge in the door latch area, preventing full closure. Carefully inspect and remove any trapped material.
Check door latch alignment: The door catch (on the door itself) must align precisely with the latch housing (on the machine body). If the door has been knocked or the machine has been moved roughly, alignment can shift. Gently adjust the door position by loosening hinge screws slightly, realigning, and retightening.
Lock mechanism failure: If the door closes properly but DE persists, the electronic locking mechanism has likely failed. You might hear clicking as the machine attempts to engage the lock. This is an internal electrical component requiring professional replacement—typically a new door interlock assembly.
LE indicates a motor overload or mechanical issue, often triggered by heavy loads or internal strain.
The LE code appears when the motor draws excessive current trying to turn the drum, suggesting mechanical resistance or electrical problems preventing normal operation. The machine’s control board monitors motor current constantly, shutting down if it exceeds safe limits to prevent motor damage or fire risk.
Troubleshooting approach:
Reset the machine: Turn off and unplug for 60 seconds, allowing the control board to fully reset. Plug back in and try again. Temporary electronic glitches occasionally trigger LE errors that clear with reset.
Reduce load size: Overloading creates excessive resistance. Remove half the laundry and try again. If the error clears, you’ve simply exceeded capacity.
Check for obstructions: Foreign objects—coins, hairpins, underwire from bras—can wedge between the drum and outer tub, preventing rotation. Try rotating the drum by hand with the machine off. It should turn smoothly with slight resistance. Grinding, catching, or complete inability to turn indicates mechanical obstruction requiring professional disassembly.
Bearing failure: Worn drum bearings create excessive friction, overloading the motor. Symptoms include loud rumbling during spin, rust stains on laundry, or water leaking from underneath. Bearing replacement is a major repair requiring machine disassembly—often uneconomical compared to replacement for older machines.
Persistent LE errors after reset and load reduction require professional diagnostics to distinguish between motor faults, bearing problems, or control board issues.
FE means the washer is overfilling, often due to a faulty water inlet valve or pressure sensor issue.
The FE code (Fill Error) appears when water level exceeds the maximum safe level. This prevents flooding, water damage to electrical components, and potential overflow from the drum. Multiple sensors monitor water level—if these detect overfilling, the machine immediately stops intake and displays FE.
Immediate action:
Turn off water supply: When FE appears, immediately turn off the inlet taps. A stuck-open inlet valve can continue filling even with power off, potentially causing serious water damage.
Drain manually: Most LG machines allow emergency draining via the pump filter. Use the filter access to slowly drain excess water into a shallow container. This prevents overflow while you investigate.
Common causes:
Stuck inlet valve: The solenoid valve controlling water entry can stick open due to debris, scale buildup (common in London’s hard water), or electrical failure. Even with power off, water pressure can force water through a stuck valve. This requires valve replacement.
Pressure sensor fault: The water level pressure sensor might incorrectly report water level, causing the machine to continue filling past the safe point. This electronic component requires professional testing and replacement.
Control board malfunction: Less commonly, the main PCB fails to close the inlet valve despite correct sensor readings. This complex diagnosis requires specialist testing.
FE errors involving internal components need professional repair—internal electrical and water systems are not DIY-safe. For reliable appliance repairs across London, contact qualified engineers.
TE or HE indicate a heating fault, usually linked to a faulty temperature sensor or heating element.
Both codes relate to water temperature problems. TE (Temperature Error) and HE (Heating Error) appear when the machine cannot achieve or maintain required wash temperatures. This affects wash quality—many cycles depend on specific temperatures for effective cleaning and stain removal.
Why water stays cold:
The most obvious symptom is cold water remaining cold throughout the wash. Touch the door glass 15 minutes into a hot wash cycle—it should feel warm. If it stays cold, heating has failed.
Temperature sensor malfunction: The thermistor (temperature sensor) might report incorrect temperatures to the control board. If the sensor falsely reports the water is already hot, the heating element never activates. Conversely, if it reports persistently cold readings despite actual heating, the code appears because the machine “thinks” heating has failed. Sensor resistance can be tested with a multimeter—typically around 50,000 ohms at 25°C, decreasing as temperature rises.
Heating element failure: The element itself may have burnt out or developed electrical faults. Heating elements operate at 230V and draw significant current—electrical failures manifest as complete heating loss or tripped circuit breakers. Testing requires disconnecting power, accessing the element (usually through the rear panel), and checking for continuity with a multimeter.
Both sensor and element replacement require accessing internal components under warranty-voiding conditions. Professional repair is strongly recommended unless you have electrical appliance repair experience.
CL means Child Lock is activated and not a fault with the washing machine.
This is the most commonly misunderstood “error code”—it’s actually a feature indicator, not a fault. CL (Child Lock) prevents accidental program changes or door opening by curious children pressing buttons during operation.
Why it prevents button response:
When Child Lock activates, all buttons except the power button become disabled. Pressing wash cycle buttons, temperature adjustments, or spin speed controls produces no response, leading many users to suspect machine failure.
How to disable Child Lock:
The deactivation method varies slightly by LG model but generally involves pressing and holding a specific button combination for 3-5 seconds. Common combinations include:
- Hold the “Temp” and “Spin” buttons simultaneously for 3 seconds
- Press and hold the “Child Lock” button (if present) for 3 seconds
- Hold “Prewash” and “Extra Rinse” together for 3 seconds
Check your specific model’s manual for the exact combination. Once deactivated, CL disappears and normal button function resumes.
Common confusion with faults:
Users often report “the buttons don’t work” without noticing the CL display. If your machine shows CL and won’t respond to button presses, it’s functioning correctly—simply deactivate Child Lock rather than calling for repairs.
SE indicates a motor or hall sensor fault affecting drum rotation.
The SE code (Motor Sensor Error) appears when the control board cannot properly communicate with the motor’s position sensors (hall sensors). These sensors tell the control board the motor’s rotational position and speed, allowing precise control during different cycle phases—gentle agitation during washing, gradual acceleration during spin, controlled deceleration at cycle end.
Symptoms:
The drum may not spin at all, rotate erratically, or fail to reach full spin speed. You might hear the motor attempting to start—humming or clicking sounds—without successful rotation. In some cases, the machine completes wash and rinse but fails at the spin phase when SE appears.
Sensor communication issues:
Hall sensors are magnetic sensors detecting motor shaft position. Wiring connections between sensors and the control board can loosen through vibration, corrode from moisture, or suffer physical damage. Sometimes reseating these connections resolves SE errors, but accessing them requires disassembling the machine.
Motor control board faults:
The motor control module processes hall sensor signals and drives the motor accordingly. Electronic failures in this module prevent proper motor operation even with functional sensors and motor. This sophisticated electronics requires specialist diagnostics to distinguish from sensor or motor failures.
When engineer diagnostics are required:
SE errors are beyond DIY troubleshooting. Professional diagnostics using multimeters and manufacturer diagnostic software can test sensor resistance, verify control board signals, and isolate faults to specific components. Attempting repairs yourself risks electric shock from high-voltage motor circuits and invalidates warranties.
CE signals excessive motor current, usually caused by overload or internal motor control problems.
The CE code (Current Error) appears when the motor draws more electrical current than safe limits allow. This protects both the motor and home electrical circuits from damage due to overcurrent conditions that could cause overheating, component failure, or fire risks.
Common causes:
Overloading: Excessive laundry weight creates mechanical resistance, forcing the motor to draw high current attempting to turn the drum. This is the most common cause and easiest to resolve.
Mechanical obstruction: Items jammed between drum and tub, failed bearings, or foreign objects create resistance triggering high current draw similar to overloading.
Motor control failure: The motor control module regulates current delivery to the motor. Internal failures can cause uncontrolled current flow, triggering CE protection.
Reset procedure:
- Turn off and unplug the machine
- Remove laundry and check for obstructions
- Wait 2 minutes for capacitors to discharge
- Plug back in and try a reduced load
- If CE reappears immediately or persists with small loads, professional repair is required
Persistent CE faults requiring professional repair:
CE errors that occur with empty drums, appear immediately on cycle start, or return despite load reduction indicate motor, control board, or wiring faults beyond user troubleshooting. These electrical faults need trained technician diagnosis and repair.
Blockages and load issues are often DIY-fixable, but electrical, motor, or heating faults require professional repair.
Safe DIY troubleshooting:
You can safely attempt:
- Cleaning pump filters (OE errors)
- Checking and cleaning inlet filters (IE errors)
- Redistributing or reducing loads (UE, LE, CE errors)
- Ensuring proper door closure (DE errors)
- Turning water taps fully on (IE errors)
- Deactivating Child Lock (CL display)
- Basic resets—unplugging for 60 seconds
When to stop and call professionals:
Never attempt DIY repair for:
- Heating element replacement (TE/HE errors)
- Motor or sensor faults (SE/LE/CE errors)
- Control board repairs (any persistent error)
- Inlet valve replacement (FE errors)
- Door lock mechanism replacement (DE errors)
- Any repair requiring machine disassembly beyond filter access
Clear warnings:
Electrical safety: Washing machines operate on 230V mains electricity. Internal components remain live even when switches are off unless unplugged. Water and electricity create lethal shock risks. Never open panels or access internal components while plugged in.
Water damage risks: Incorrect reassembly can cause water leaks damaging floors, ceilings (in flats), and belongings. Professional repairs include pressure testing and leak checks.
Warranty implications: Opening sealed components voids manufacturer warranties. If your machine is under warranty, any self-repair invalidates coverage.
Landlord responsibilities: Landlords providing washing machines in rental properties must ensure professional repairs maintain safe operation. DIY fixes by landlords without appropriate qualifications may breach duty of care to tenants.
Seek professional repair services if error codes persist, involve heating or motor faults, or return after resetting.
Situations requiring immediate professional help:
- Any burning smell from the machine
- Water leaking from underneath or around the door
- Loud grinding, banging, or scraping noises
- Sparking or smoke from any part of the machine
- Error codes appearing on brand-new machines (warranty service)
- Multiple different error codes appearing in sequence
Call an engineer when:
- Error codes persist after basic troubleshooting (cleaned filters, checked taps, reduced loads)
- Electrical errors (TE, HE, SE, CE) appear
- FE (overfilling) occurs
- DE persists with clear door alignment
- Machine has progressively worsening symptoms over weeks
Benefits of professional diagnosis:
Qualified engineers can test components individually, access manufacturer diagnostic modes revealing detailed fault information, and order specific replacement parts ensuring correct fixes. They carry common parts (pumps, valves, sensors) enabling same-visit repairs for frequent faults.
For reliable washing machine repairs across all London areas, professional engineers diagnose faults accurately and complete repairs safely. Whether you’re experiencing persistent error codes, suspect component failure, or need routine appliance maintenance, expert support ensures your washing machine operates reliably.
Regular filter cleaning, balanced loads, and proper installation help prevent most common LG error codes.
Monthly maintenance:
-
- Clean the pump filter: Even without OE errors, clean the filter monthly. This prevents gradual buildup that eventually causes drainage problems.
- Inspect inlet filters: Check and rinse inlet filters every 3-6 months, more frequently in hard water areas.
- Wipe door seals: Remove detergent residue and debris from door gaskets weekly, preventing DE errors from poor door closure.
- Best practice during use:
- Avoid overloading: Respect capacity limits. Overloading causes UE, LE, and CE errors while reducing wash quality and stressing components.
- Use correct detergent amounts: Excessive detergent creates excess suds affecting sensors and promoting buildup in pumps and hoses.
- Empty pockets: Remove coins, tissues, and small items preventing pump filter blockages and mechanical damage.
- Don’t leave wet laundry: Remove laundry promptly after cycles, preventing mildew in the drum and gasket deterioration.
Installation quality:
- Ensure level installation: Machines must sit level to balance loads properly and prevent premature bearing wear.
- Secure hoses: Check drain and inlet hoses aren’t kinked or stressed. Replace every 5 years regardless of appearance—internal deterioration isn’t visible.
- Adequate ventilation: Don’t box machines into sealed cupboards. Air circulation prevents moisture buildup and overheating.
Preventative mindset:
Monthly filter cleaning takes 5 minutes and prevents most common errors. Proper loading practices extend machine lifespan by years. These simple habits maintain reliable operation and avoid inconvenient breakdowns requiring repairs.
