LG washer error codes name a family of faults, not a fault. OE covers a kinked hose, a filter with a coin in it and a pump that is electrically dead — one code, three afternoons, three different bills. What separates them is not on the display at all. It is the stage the cycle had reached when the code appeared, and no chart records that for you.
So this page groups every code LG publishes into the family it belongs to, in LG’s own words, with a link to the full diagnosis. It also flags where LG’s documentation does not agree with itself, because on this brand one code carries two different meanings on two pages that are both live today.
LG contradicts itself on dE2, and both pages are live
Start here, because this is the one that costs people money. LG’s dedicated page for the door-lock family says “A dE2 error code indicates that the drawer is closed, but not locked” (Front Load Washer — What are dE, dE1, and dE2 Error Codes?), and the string E30 does not appear anywhere on it. LG’s front-load code list says “A dE2/E30 error code indicates that the door is closed but not locked” (LG Front Load Washer — Error Code List (New)), pairing E30 with dE2 and naming a different part of the machine. Both pages were opened and read on 2 September 2026, and neither acknowledges that the other exists.
The internet resolves this confidently in one direction or the other, usually by copying whichever LG page the writer happened to open. This page will not, because nothing available settles it: no third LG page adjudicates, and the two that disagree carry identical authority. The honest version is the practical one. If your machine shows dE2, check the door latch and the dispenser drawer before accepting a diagnosis from anyone, LG’s help library included. One of those checks takes ten seconds, and half of LG’s customers are being told to skip it.
There is a second oddity on those pages that hints at how the disagreement got there. Both print the word “dryer” inside a washer procedure — the dE2 causes open “This can be caused if there is too much laundry in the dryer” — which is LG’s own copy-paste, not a transcription error at this end.
Top-load and front-load LG machines do not share a code set
This is the mistake that sends people down the wrong page, and it is easy to make because the characters overlap. LG documents the two machine types separately, identical letters do not always carry identical definitions, and a top-loader frequently has no display to print a code on. Read a front-load chart against a top-load machine and you get a confident answer to a question your washer never asked.
Take dE itself. The front-load page: “A dE error code on your LG front load washing machine indicates that the washer door was unable to lock.” The top load LED blinking error codes page gives the same two characters a different component: “A dE error code means that the washer was not able to lock the drawer.” Same letters, different machine, different part.
The bigger difference is the panel. Many LG top-loaders report faults by blinking the cycle indicator lights they already have, because a row of LEDs is the only vocabulary that panel owns. LG’s page is built as a filter rather than a list for that reason: it asks you to “Filter the error codes by selecting the options that are blinking” and works backwards from there. The consequence is one instruction — video the panel, do not photograph it. A still frame cannot tell you whether two lights blink together or alternate, and that distinction is the entire message. Method: washing machine blinking lights, no code.
A code names a family. Where the cycle stopped names the fault
Every code chart on the internet, LG’s included, stops at the definition — and the definition is the coarse half of the answer. OE tells you the water level did not fall far enough in the time allowed, and it cannot tell you why, because knowing why is not something a pressure reading can do. A slow drain, a filter packed with lint, a kinked hose and a pump with no electrical life left all produce the identical two characters.
The machine tells you which one you have anyway — not through the display, through behaviour. A pump you can hear running while the water creeps down is a restriction. A pump that is silent when it should be working is not a restriction at all, and no amount of filter cleaning changes that. So before you look anything up, write down two things: the code, and the point in the cycle it appeared at.
| The code appeared… | What that narrows it to |
|---|---|
| Before the cycle will start | Door or drawer lock, water supply, or Child Lock. It never got permission to begin |
| During fill, or fill never finished | Supply side: tap, hose, inlet screen, or the sensor reading the level |
| Mid-wash, water still in the drum | Drain, motor, heater or sensor. It was running and chose to stop |
| At the drain-to-spin handover | Almost always drain or suds. No washer accelerates a drum it believes still holds water |
| As spin ramps up, repeatedly | Balance. The load first, the levelling feet second |
| At different points on different cycles | An intermittent sensor, or a supply problem. Hardest to pin down |
A reader who arrives with “OE at the end of the wash, pump audible” is most of the way to an answer. A reader who arrives with “OE” has a family of four. The same family-first method on other brands: Samsung washer error codes, Maytag washer error codes.
The full LG washer error codes table
Grouped into fifteen fault families rather than listed alphabetically, because that is how the machine is organised and how you will actually search it. LG prints the same fault three ways across display generations and regions — OE, E03 and E21 are one code, not three — so the numeric variants share a row. A sixteenth row holds the three LG washer error codes that are not errors at all. Read the quotation marks carefully. Quoted rows are LG’s own wording from the front-load error code list and the top load LED blinking codes page, both read on 2 September 2026. Unquoted rows are plain-language descriptions written here, because the sentence on LG’s page could not be captured in full — and a paraphrase inside quotation marks is a misquote.
| Family | Codes | What LG says | What it usually is | Full diagnosis |
|---|---|---|---|---|
| Fill | IE E02 E10 | “The [IE,E02,E10] (Water Inlet Error) error occurs if the tub does not fill to an adequate level within a specified period.” | A tap not fully open or a clogged inlet screen, not a valve | not filling with water |
| Overfill | FE E04 E12 | “The FE/E04/E12 error indicates a problem with water overfilling. During normal operation, the drain pump is activated to prevent leaks.” | A valve not closing, or a level sensor reading high. The pump running on its own is the machine protecting your floor | washing machine overflowing |
| Drain | OE E03 E21 DR | “An OE/E03/E21 error code indicates the washing machine is unable to drain the water used during the wash cycle.” | Pump filter or drain hose. A dead pump is the minority case | LG washer won’t drain |
| Water level sensor | PE E33 | “The PE error code indicates that the water level sensor is malfunctional.” · Top-load: “The PE error indicates that the water pressure sensor isn’t working properly.” | Sits behind fill and drain symptoms alike, which is why it gets misdiagnosed as either | won’t drain, not filling |
| Door not closed | dE dE1 E01 | “A dE/dE1/E01 error code indicates that the door is not closed properly.” · Dedicated page: “the washer door was unable to lock” | Laundry caught in the gasket, or an overfilled drum pushing the seal | door locked after cycle |
| Closed but not locked | dE2 E30 dL | LG’s two pages disagree — “the drawer is closed, but not locked” on one, “the door is closed but not locked” on the other. Top-load dL: “the door latch switch is not functioning properly.” | Check both: the latch path, then the dispenser drawer. Neither takes long | door locked after cycle |
| Unbalanced load | UE uE | “Occurs when the laundry is piled up on one side of the drum, causing an imbalance, despite the drum’s movements to evenly distribute the load.” | A load too small as often as one too big. Two shoes cannot balance a drum | washer won’t spin, how to level a washer |
| Suds | Sud | “If the washing machine detects too many suds, it displays this error code and adds a suds reducing cycle. This adds about 2 hours to the cycle time.” | Detergent dose, essentially always. LG prices it at two hours | signs of too much detergent |
| Tub will not spin | LE LE1 | “An LE error code is displayed when the tub fails to spin.” | Something jamming the drum, or a load the motor cannot start | drum not turning |
| Motor over-current | CE | An over-current in the motor’s electrical circuit | An overloaded drum before a failed motor. Empty it, run a Rinse and Spin | washer won’t spin |
| Heating | tE HE dHE | A heating fault, commonly at the thermistor; dHE on wash-dry combo models | Only on models with a heater or dry function. Shows as long cycles first | washer stops mid cycle |
| Leak | AE | A leak detected inside the appliance | Often the sensor rather than a puddle. A dry floor does not clear it | washing machine leaking water |
| Vibration sensor | vS uS | A vibration sensor fault | Level and load are the only variables you control. Beyond that, a part | washer shakes during spin |
| Freeze | FF u51 | A freeze condition detected in the water path | A garage or unheated utility room in winter. Not a machine fault | not filling with water |
| Power and control board | PF PS EE E6 SE | A power failure, a supply voltage fault, or an internal self-check failure | PF is an interruption, not damage. The rest are service codes | how to reset a washing machine |
| Not faults at all | CL tCL Cd | “CL is not an error code, but an indicator that the child lock feature is active.” · “A tCL error means it is high time to run the tub clean cycle.” · Cd: the drying cycle is complete | Nothing is wrong. tCL is a counter; CL survives a reset because it is not a fault to clear | control lock and child lock, tub clean cycle |
Four LG code pages Google still ranks, and none of them exist
Search for an LG code and Google hands you LG’s own support library near the top of page one. Several of those results no longer lead anywhere. LG retires help-library articles without redirecting them, so the URL survives, the old title stays in the index, and clicking it lands you on a generic “Troubleshooting” hub asking you to select a product.
Four were checked by hand on 2 September 2026 — all four ranking, all four now serving that hub with no code content: lg-washer-error-code-list--20150140270078, the older lg-front-load-washer-error-code-list--20153792986252, lg-washer-what-is-a-front-load-washing-machine-oe-error-code--1337714738535 and lg-washer-what-is-a-top-load-washing-machine-ueub-error-code--1394563702295. The top-load code list at --20154403824104 went the same way earlier this year.
The last one has a real cost attached. It was the page documenting lowercase uE against uppercase UE — the machine still trying to rebalance versus the machine having given up — and with it gone, that distinction survives only in retailers and repair blogs citing a source that is not there any more. It is probably right. It is no longer LG’s word, and this page will not pretend otherwise.
The habit that fixes this is small: open the link before you trust the answer behind it. A search result is a claim about a page, not a reading of one. Same failure mode, every brand: error code not in the manual.
Capture the code before the power cycle clears it
A reset clears the stored code. That is not a side effect — it is the entire function, which is why photographing the panel comes first. On this brand a single character moves a code between families, and “I think it was dE something” is not a diagnosis anyone can work from, least of all the technician you pay to guess at it.
LG’s documented procedure for the door-lock family is duller than the internet’s version: power the washer off, unplug it or switch off the breaker, and then — with the power still disabled — press and hold START/PAUSE for five seconds before restoring power. Holding the button with the machine dead is what discharges the board, and it is the step most third-party write-ups drop. You will also find an “open and close the door six to twelve times within twelve seconds” reset repeated confidently across appliance sites. It is not on LG’s dE/dE1/dE2 page, which gives the button-hold and nothing resembling a door-cycling trick — the same pattern as Whirlpool’s lid-cycling reset, which is on a dozen sites and in none of Whirlpool’s documentation. Method: how to reset a washing machine.
If the same code comes back at the same stage, the reset did not fail. It worked: it cleared the state, the machine re-tested the condition, and the condition is still there. That is a result — and the moment to stop resetting and start diagnosing.
When an LG code means stop rather than troubleshoot
Most of these codes are the machine refusing to proceed, which is a safety system working. A few conditions are not, and they outrank whatever the display says.
- A burning smell, or scorching at the plug. Stop at the breaker, not at the plug.
- A breaker or GFCI that trips again after being reset. It is doing its job. Re-arming it repeatedly is the wrong response every time.
- Water on the floor near a live outlet. Power off first, diagnose second.
- The drain hose and pump filter both confirmed clear, and the pump silent when it should run. Procedure: how to clean a washing machine filter.
- The same code, at the same stage, after one full documented reset, twice.
The last two are not stop-use conditions. They are where more checking costs more than the call would.
FAQ
What does dE2 mean on an LG washer?
LG’s own pages give two answers. Its dedicated dE/dE1/dE2 page says the drawer is closed but not locked; its front-load code list says dE2/E30 means the door is closed but not locked. Both were live on 2 September 2026, so check the latch path and the dispenser drawer.
Are LG top-load and front-load error codes the same?
No. LG publishes them separately and the same letters can mean different things: dE is a door that would not lock on a front-loader and a drawer that would not lock on a top-loader. Many top-loaders have no display and blink cycle lights instead.
How do I clear an LG washer error code?
Photograph the panel, then power off, kill the breaker or unplug, hold START/PAUSE for five seconds with the power disabled, and restore power. That is LG’s documented procedure for the door-lock codes. One reset is worth doing. The fourth is not.
What is the most common LG washer error code?
OE and its variants E03 and E21 — the drain family, and the most over-repaired, because the fix is usually the filter or the drain hose rather than the pump.
Does an LG error code mean I need a repair?
Frequently not. CL, tCL, Cd, PF, UE and Sud describe conditions, not failures. The suds family is a detergent dose that LG says costs about two hours, not a part.
My LG code is not on this list. What now?
Check the machine type first, since the two code sets differ, then look for a leading or trailing digit that moves a code into another family. Then open LG’s live list against your model number — and do not trust a Google result for an LG code page until you have seen the code on it.
—
An LG code narrows your machine to a system. The stage it stopped at narrows it to a component. And when the manufacturer’s own two pages disagree about which part a code refers to, the answer is to check both — not to pick the one that ranks higher.
