LG Washer OE Error Code: What It Means and How to Fix It

By Dan Mercer · Published October 5, 2026 · Updated October 6, 2026 · Codes covered: OE, E03, E21 · Sources

An OE code on an LG washer means it can't drain the water out in time. On front loaders it's usually a clogged drain pump filter, and on both types it's often a kinked, frozen or badly placed drain hose. You can fix most cases yourself without tools.

Some newer LG front loaders show the same drain error as E03 or E21.

What the OE code means

LG calls OE a "Water Outlet Error": the washer is draining slowly or not at all. The cycle stops, usually with water still in the drum or tub.

OE is a drain code, not an overflow code. People often mix this up, because on Samsung washers OE means overflow. On LG washers, too much water shows as FE ("Overflow Error"), which LG's manual blames on a faulty water valve. That one needs service: turn off the taps, unplug the washer and call LG.

Front-load vs. top-load. Both use OE for a drain problem, and both share the hose checks. The difference is the filter:

• Front loaders have a drain pump filter behind a small access cover at the bottom front. LG's manual says OE blinks when this filter is clogged.
• Top loaders: LG's top-load troubleshooting doesn't include a pump-filter step. It focuses on the drain hose, foreign objects inside the hose, freezing, and the house drain. Check your manual to see if your model has a filter.

Related codes. FF ("Freeze Failure") means the hoses or pump may be frozen. LG says OE can also appear when the drain hose freezes.

Likely causes (most common first)

1. A clogged drain pump filter (front loaders). Lint, coins, hairpins and small items collect here.
2. A kinked, pinched or crushed drain hose. LG says vibration can kink the hose, especially if the washer is pushed tight against the wall. LG recommends at least 4 inches of space behind the washer and 1 inch on each side.
3. The drain hose is too high. LG's manuals say the end of the hose must be no more than 96 inches (2.4 m) above the bottom of the washer. The small LG SideKick pedestal washer has a lower limit of 53 inches.
4. Objects stuck in the drain hose, such as coins (LG mentions this for top loaders).
5. A frozen drain hose or pump in a cold garage or basement.
6. A clogged house drain, meaning the standpipe or floor drain the hose empties into.
7. Too many suds. LG says excess suds can create air pockets the pump can't push out, which triggers a drain error.
8. A failed drain pump or wiring fault.

How to fix it, step by step

Try these in order, and run a Spin Only or Rinse+Spin cycle after each step to see if the code clears.

1. Check the drain hose. Pull the washer out carefully and straighten any kinks or flattened sections. Make sure the end is no higher than 96 inches above the bottom of the washer, unless your manual says otherwise.
2. Listen to the pump (front loaders). LG's test:
   • Press Power, set Spin Speed to High, and press Start/Pause to run a spin-only cycle.
   • For the first 15 seconds, listen for a hum, and possibly the sound of water draining.
   • A hum means the pump motor is running, so the problem is probably a clog. Go to step 3.
   • No hum at all points to the pump or its wiring. See "Test the part" below.
3. Clean the drain pump filter (front loaders). The water may be hot, so let it cool first.
   • Turn off the washer and unplug it.
   • Open the drain pump filter cover at the bottom front. Put down towels and a shallow pan.
   • Unclip the small drain tube, pull out its plug and drain the water into the pan, a little at a time.
   • Twist the pump filter counterclockwise to remove it. Clean the filter and the opening, using a toothbrush if you need to.
   • Put the plug back in the drain tube and clip it back in place.
   • Twist the filter back in clockwise until it's snug, then close the cover.
4. Run Tub Clean if you found suds or debris. LG suggests a Tub Clean cycle after clearing the filter. If the filter was already clean, LG says suds may be the cause, so use less detergent from now on. Use HE detergent.
5. Clear the hose (top loaders). LG suggests disconnecting the drain hose from the washer and removing any coins or objects with tweezers. Reconnect it securely.
6. Thaw a frozen washer. Pour warm water, 122–140°F (50–60°C), into the drum or tub. Close the door or lid and wait 1 to 2 hours. You can also wrap the drain hose in a cloth soaked in warm water. Then run Spin Only to drain it. Never use boiling water, which LG says can damage the washer.
7. Test your home's drain. Take the drain hose out of the standpipe, hold it over a bucket, and run a spin-only cycle. If it drains well, the standpipe or house drain is clogged and needs clearing, not the washer.
8. Stop if OE keeps returning. If the hose, filter and house drain are all clear, LG says the washer may need repair.

Test the part

If the pump doesn't hum, or it hums but still won't drain with a clean filter and hose, the likeliest failed part is the drain pump. Here's a basic check with the washer unplugged.

1. Unplug the washer and turn off the taps. Drain as much water as you can first (step 3 above, or bail out a top loader).
2. Look inside the filter housing (front loaders). With the filter out, shine a flashlight in. Remove anything wrapped around or jammed against the small pump impeller, like hair, string or a coin. Don't use metal tools.
3. Reach the pump's connector. This depends on the model. It usually means removing a lower or rear panel, and on some top loaders tipping the washer. Washers are heavy, so get help, check your manual, and watch for sharp edges.
4. Photograph the wires, then pull the connector off by its housing, not the wires.
5. Check the pump coil for continuity. Set your multimeter to the lowest ohms setting and touch the probes to the pump's two terminals.

Swipe the table sideways to see every column.

1. Read the result. OL means the pump coil has failed and the pump needs replacing. A reading only shows the coil is intact. A pump can pass and still be jammed or weak.

If the pump passes and OE persists, stop and call a pro. The next step is checking whether the control board is powering the pump, which is a live-voltage test and not a DIY job.

Safety notes

When to call a pro

Call LG or a qualified appliance technician if:

• OE keeps returning with a clean filter, a straight hose and a clear house drain.
• You don't hear the pump hum during a spin-only cycle.
• The pump coil reads open (OL), or the impeller is broken.
• You see FE (overflow) or the washer keeps filling with water. Turn off the taps and unplug the washer first.
• Water is leaking from under the washer, or you can see damaged wiring.
• Your washer is under warranty. Check the terms before opening any panels.
