LG Washing Machine OE Error
Applies to front-load and top-load washers; LG's top-load list labels OE the “outlet error”.
Your LG washing machine has stopped with water still inside because it cannot get rid of the water it used. LG groups the causes of OE into three: a clogged drain pump filter, a drain hose that is pressed or kinked, and — in cold weather — a drain hose that has frozen. Most OE errors are one of those three, not a failed pump.
Work through the checks in the order below. The spin test in step 1 tells you early whether the blockage is in the machine or in your house drain, which decides everything that follows.
Safety first
- Switch the washer off and unplug it before opening the drain pump filter cover or reaching behind the machine.
- Water trapped in the tub can be hot. Drain it slowly through the residual water hose into a shallow pan, and keep towels ready — opening the pump filter releases whatever water is left.
- If you are thawing a frozen machine, use warm water (50–60 °C), never boiling — LG warns boiling water is a burn risk.
Common causes
A clogged drain pump filter (front loaders)
The pump filter catches lint, coins and debris before they reach the pump. LG names it as one of the main causes of OE: once it blocks, water cannot leave the tub.
A drain hose that is pressed or kinked
If the washer sits too close to the wall, the hose kinks behind it and throttles the flow. LG specifies at least 10 cm (4 inches) of clearance at the back and 2 cm (1 inch) on each side.
A blocked house drain
Sometimes the washer is fine and the drain it empties into is blocked. Step 1 separates this from a machine fault before you clean anything.
Objects inside the drain hose
LG's top-load guidance lists coins and similar objects clogging the hose itself — the hose needs disconnecting and the object removing with tweezers.
A frozen drain hose
Prolonged cold weather can freeze the water sitting in the hose. LG: OE in freezing weather points at the drain hose, and the machine needs thawing before it can drain.
A failing drain pump
If the filter, the hose and the house drain are all clear and water still does not move, the pump itself is the remaining suspect — that is service work, below.
Step-by-step checks
- Run the spin test firstLift the drain hose out of the drain, switch the washer on and run a Spin (or Spin Only) cycle. If water flows freely out of the hose, the washer is draining fine and the house drain is blocked — clean the drain and the error is explained. If no water comes out, the fault is inside the machine; continue below.
- Clean the drain pump filter (front loaders)Power off and unplug. Open the access cover on the lower front of the washer, pull out the residual water hose and remove its cap to drain the tub water into a pan. Then turn the pump cap counter-clockwise, take the filter out and clean it and its opening with a soft brush or toothbrush under warm water. Refit the filter securely — a loose cap leaks — replace the hose cap and close the cover.
- Straighten the drain hoseFollow the hose from the back of the washer to the drain. Remove kinks and sharp bends, and make sure the machine is not crushing it against the wall — keep the clearances LG specifies (10 cm behind, 2 cm at the sides). On a top loader, LG adds that the hose should run gently downwards rather than raised or folded.
- Clear objects from the hoseIf the hose still runs slowly, disconnect it and check inside for coins or other objects. LG's own instruction is to remove anything clogging it with a pair of tweezers, then reconnect.
- Thaw it, if the machine may have frozenPour warm water (50–60 °C) into the tub, close the door and wait 1–2 hours for the drain pump and hose to thaw; a warm wet cloth wrapped around the hose helps. Then run Spin. If no water drains, the ice has not fully melted — wait and try again.
- Test with a fresh cycleRun a new cycle and watch it drain. LG's front-loader guidance is blunt: if OE appears again after these checks, the unit may require a service call.
When to call a technician
Call for service when OE returns after the filter is clean, the hose is straight and clear, and the spin test has ruled out the house drain. At that point, on LG's own account, the drain pump is what is left — and pump replacement is not a DIY step.
Call sooner if the machine leaks from the filter cover after refitting (stop, reseat the cap once; a damaged seal is a service item), or if the drum holds water you cannot drain at all through the residual hose.
Model differences
| What you have | What changes |
|---|---|
| Front-load washer (incl. WashTower washer) | There is a user-cleanable drain pump filter behind the lower-front access cover — it is LG's first check for OE, and the steps above follow LG's order. |
| Top-load washer | LG's top-load list labels OE the “outlet error” and works through the hose — position, kinks, objects, freezing — rather than a pump filter. Follow the hose steps; your model's manual governs anything further. |
| OE after freezing weather, any model | Treat it as a frozen hose first (LG groups OE with its freeze guidance) and thaw before suspecting the pump. |
One-page checklist — OE
- Spin test done — machine fault or house drain identified
- Drain pump filter cleaned and cap refitted securely (front loaders)
- Drain hose straight, unkinked, clearances kept (10 cm back, 2 cm sides)
- Hose checked inside for coins and objects
- Frozen hose thawed with warm water, if winter is a factor
- Fresh cycle run — drains fully, no OE

Frequently asked questions
Is OE a serious fault?
Usually not. LG's own cause list for OE is a clogged drain pump filter, a kinked drain hose, or a frozen drain hose — all checkable at home. OE only points at the drain pump itself once those three are eliminated.
There is water stuck in the drum. How do I get it out?
On a front loader, open the lower-front access cover, pull out the residual water hose, remove its cap and drain the water into a shallow pan — LG's procedure before cleaning the filter. The water may be hot, so drain it slowly.
Does my top loader have a drain pump filter to clean?
LG's top-load error list handles OE through the drain hose — its position, kinks, trapped objects and freezing — and does not route you to a pump filter. Follow the hose checks and your model's manual.
How often should the drain pump filter be cleaned?
LG's troubleshooting guidance for drainage errors recommends cleaning the drain pump filter monthly — it is maintenance, not just an OE fix.
OE appeared during freezing weather. Is the pump broken?
Probably not. LG lists a frozen drain hose as a standard OE cause: thaw the tub and hose with warm water (50–60 °C), wait 1–2 hours, then run a Spin cycle before suspecting any part.
