LG Washer Error Codes: Meanings & Quick Fixes

A blinking error code on your LG washer looks alarming, but it is really just the machine pointing at one specific fault. Front loader or top loader, the code narrows the cause so you are not guessing.

Most codes clear with something simple: straightening a hose, clearing the drain filter, or spreading out a wet load. This guide translates the common LG washer error codes into plain steps, and flags the few that genuinely need a technician.

Key Takeaways

Here are the essentials for reading LG washer error codes:

What a code is: Each LG washer error code names one fault, such as a drain problem (OE), a water-supply problem (IE), or an unbalanced load (UE).
Most common codes: OE (drain), IE (water supply), and UE (unbalanced load) are the most common codes, and all three usually trace to a hose, filter, or load issue rather than a broken part.
Newer displays: Recent LG washers show alphanumeric codes instead of letters; E02 is IE, E03 is OE, and E01 is dE.
Try a reset first: Unplugging the washer for a minute clears many glitch-based codes before any repair is needed.

What Do LG Washer Error Codes Mean?

Each LG washer error code points to one specific fault, such as a drain problem, a water-supply issue, or a door or motor fault, so matching the code to its meaning below tells you exactly what to check first. If your model shows an alphanumeric code instead of letters, it points to the same fault: E01 is the door (dE), E02 is the water inlet (IE), and E03 is drainage (OE), per LG’s error-code list.

Error Code FE

What It Means: Water overflow error. The water valve is letting too much water into the drum, and the pump is running to drain it out automatically.

How to Fix It: Close both water taps behind the washer immediately to stop the flow. This usually indicates a faulty water inlet valve that is stuck “open.” You will likely need to replace the valve assembly.

Error Code LE

What It Means: Locked Motor error. The motor can’t spin properly. This often happens if the washer is overloaded with heavy towels or blankets, straining the motor.

How to Fix It: Open the door and remove some heavy items to lighten the load. If the drum is empty and it still happens, let the machine cool down for 30 minutes. Perform a reset (unplug, wait, plug back in) and try a Rinse + Spin cycle.

Error Code OE

What It Means: Water Outlet error, one of the most common codes. The washer shows it after it has tried and failed to drain for about 13 minutes, so it is telling you water is stuck in the tub ⁽¹⁾.

How to Fix It:

Check the drain hose behind the machine; ensure it isn’t kinked or crushed.
Clean the drain pump filter (often called the coin trap). This is a small door on the bottom front of most front loaders. If this is clogged with lint or coins, water cannot drain.
If the hose and filter are clear, the drain pump itself may have failed.

Error Code dE

What It Means: Door Error. The washer cannot sense the door latched shut. Some models split this into dE1, meaning the door is not fully closed (usually laundry caught in the gasket), and dE2, meaning the door is shut but the lock switch circuit is not engaging, which points to the latch’s electrical side rather than the physical catch ⁽²⁾.

How to Fix It:

Push the door firmly to ensure it clicks.
Check for clothes stuck between the door glass and the rubber gasket.
Clean the lock mechanism with rubbing alcohol to remove gunk.
If the error persists, the door latch assembly or the hinge might be broken.

Error Code CL

What It Means: Child Lock. This is not actually an error; it is a safety feature that disables the buttons so kids can’t change settings.

How to Fix It: Look for a button on your panel marked with a lock icon (or two buttons connected by a line). Press and hold that button (or buttons) for 3 seconds to disable the lock.

Error Code UE or UB

What It Means: Unbalanced Load. The drum is spinning unevenly because wet clothes are clumped on one side.

How to Fix It: Pause the cycle and open the door, then untangle the clothes and spread them evenly around the drum. If you are washing one heavy item like a rug, add a few towels to balance the weight. LG also suggests keeping loads to about two-thirds of the drum and checking that the washer sits level, since a tilted machine reads a spin as unbalanced.

Error Code tE

What It Means: Temperature Error. The machine is sensing a problem with the heating element or the thermistor (temperature sensor).

How to Fix It: Unplug the washer for 15 minutes to let it reset. Plug it back in and run a Spin Only cycle. If the code returns when you try to wash, the thermistor likely needs replacement.

Error Code SUD

What It Means: Suds detection. You used too much detergent, or the wrong type.

How to Fix It: Do nothing at first. The washer adds a suds-reducing cycle that lengthens the run, and it pauses spinning so foam cannot leak out ⁽³⁾. Going forward, use only High Efficiency (HE) detergent and cut the amount you pour in, since most people use far too much.

Error Code IE

What It Means: Inlet Error. The washer isn’t filling with water fast enough (or at all).

How to Fix It:

Check that the water taps on the wall are fully open.
Inspect the inlet hoses for kinks.
Turn off the water, unscrew the hoses from the back of the washer, and check the small mesh screens inside the inlet valves. If they are clogged with sediment, clean them carefully.
In cold weather, check for frozen supply pipes; thawing them restores the fill.

Error Code PF

What It Means: Power Failure. The power supply was interrupted during a cycle.

How to Fix It: This usually clears itself. Restart the cycle. If it keeps happening, check that the power cord is secure and that the outlet isn’t loose. Avoid using extension cords with large appliances.

Error Code PE

What It Means: Pressure Sensor Error. The sensor that tells the machine how much water is in the tub is malfunctioning.

How to Fix It: Unplug the machine for 10 minutes to reset the electronics. If the code persists, the water level pressure switch usually needs to be replaced.

Error Code tCL

What It Means: Tub Clean. This is a reminder, not an error. The machine is telling you it’s time to run a cleaning cycle.

How to Fix It: Remove all laundry. Add a tablet of washer cleaner or liquid chlorine bleach to the dispenser. Select the “Tub Clean” cycle and press start.

Error Code CE

What It Means: Current Error. There is an electrical issue, often related to the motor or power surge.

How to Fix It: Unplug the washer immediately. Wait 60 seconds. Plug it back in and try a rinse cycle. If the code pops up again, this typically requires a professional technician to check the wiring harness or motor.

Error Code Cd

What It Means: Cool Down. This appears after a drying cycle (on combo units) is done. It spins occasionally to keep clothes from wrinkling while they cool.

How to Fix It: No fix needed. You can press the “Pause” button at any time to unlock the door and remove your clothes.

Error Code AE

What It Means: Leak (Auto-shutoff) error. A sensor in the base pan under the drum has detected water, so the washer halts the cycle to limit the leak. This is the one code to act on right away.

How to Fix It: Turn off the water taps and check the fill and drain hose connections for a slow drip or a loose coupling. Sop up the water in the base pan with a towel, then run a short cycle. If the code returns, the leak is inside the cabinet (a tub seal or an internal hose) and needs a technician.

How Do I Reset My LG Washer?

The fastest fix for many random glitches is a hard reset, unplugging the washer for a minute before calling a repairman, since that clears the computer’s memory.

Turn the washer off.
Unplug the washer from the wall (or flip the circuit breaker).
Press and hold the Start/Pause button for 5 seconds while the power is off.
Plug the machine back in and turn it on.

Why Won’t My LG Washer Drain?

An LG washer won’t drain (OE) almost always because of a clog, a kinked drain hose or a blocked drain pump filter. According to LG, the OE code appears once the washer has been unable to drain for about 13 minutes.

First, check the drain hose. It should not be inserted too far down the standpipe, and it must not be kinked.

Second, check the drain pump filter. On front loaders, there is a small square door on the bottom left or right. Open it, place a towel on the floor, and unscrew the black cap. Water will rush out, along with lint, coins, and debris. Clean this out, screw it back in, and test the machine.

FAQs

How Long Does an LG Washer Last?

An LG washer typically lasts 10 to 15 years with normal household use. You get the most life out of it by cleaning the drain pump filter monthly, running the Tub Clean cycle to clear residue, keeping loads under two-thirds of the drum, and leaving the door open between washes so the seal dries.

How Do I Use LG Smart Diagnosis?

LG Smart Diagnosis lets the washer report its fault code to LG through your phone. Open the LG ThinQ app, turn the washer on, and choose Smart Diagnosis in the app. Hold your phone’s microphone next to the “Smart Diagnosis” logo on the panel while you press and hold the marked button (often Temp) until the countdown ends, and the app then explains what the code means.

Does an LG Top Loader Have a Filter?

Yes, though the filter type depends on the model. Older LG top loaders use mesh lint bags that sit inside the drum, while newer high-efficiency models rely on a pump filter at the back of the machine or a self-cleaning pump that flushes lint down the drain on its own. Check your manual to see which one you have before hunting for a coin trap.

How Do I Fix the P5 Error on My LG Washer?

On current LG washers the P5 code (shown as PS on some panels) points to a power-supply problem, not the water level. According to LG, plug the washer straight into a wall outlet rather than a power strip or extension cord, then unplug it for 60 seconds before restarting ⁽⁴⁾. If it keeps coming back, have the outlet and the machine’s control board checked, since the problem is likely the outlet or the board rather than the wash cycle.

How Often Should I Clean the Drain Pump Filter?

Clean the drain pump filter about once a month to keep the OE drain error away. Move to every two weeks if you have shedding pets or regularly wash muddy, linty, or heavily soiled items, since that debris is exactly what clogs the filter and stops the washer draining.

Why Does My LG Top Loader Washer Smell?

An LG washer smells because bacteria and mold feed on detergent and fabric-softener residue left in the drum and around the seal. Run a Tub Clean cycle once a month with white vinegar or a washer cleaner, wipe the gasket and dispenser, and leave the lid or door open between washes so the drum dries out instead of staying damp.

What Does Error Code DL Mean?

The dL code stands for Door Lock, and it differs from dE: dE means the washer cannot tell the door is shut, while dL means the door is shut but the lock assembly will not drive the locking bar home. Try a power reset first; if the code stays, the door latch or lock switch usually needs replacing before the machine will run.

Final Thoughts

On an LG washer, the code is the diagnosis, so start with the cheapest fix before you spend a cent. A hard reset (power off, unplug for a minute, hold Start/Pause for 5 seconds) clears the random glitch behind many codes, and most of the rest come down to a kinked drain hose, a clogged pump filter, or an unbalanced load you can rebalance by hand.

Two codes are the exception and should go straight to a pro. A CE (current error) that survives a reset points at the motor or wiring harness, which is not a job for anyone but a qualified technician. An AE leak code is the one to act on right away: shut off the water taps, then get the base-pan sensor and hose connections checked before you run another cycle. When the basics do not clear the code, calling in help is the frugal choice, not the expensive one.
