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

What does the OE code mean on an LG washer?

The OE code is LG's drain error. On front-load models, LG says OE (also shown as E03 or E21 on some models) "indicates the washing machine is unable to drain the water used during the wash cycle" ^[1]. On top-load models, LG says the code appears when the washer is unable to drain water for 13 minutes ^[2].

The first character is the letter O, not a zero, although it is easy to read it as "0E". The meaning is the same on both styles of LG washer, but the checks differ. Front-load washers have a drain pump filter you can open; top-load washers do not ^[4].

The same two letters mean something else on other machines. On an LG dishwasher, OE is also a drain fault ^[5] (see our guide to a dishwasher that won't drain). On many Samsung washers, OE means the opposite problem: too much water, or an overflow ^[6]. If you are not sure which brand or series your code belongs to, check it in our error code lookup.

What causes an LG washer OE error?

LG lists four causes across its front-load and top-load pages, and none of them is a failed part: each one blocks the water on its way out. If all four check out, LG's guidance points to a repair, so a failed drain pump or control is the remaining suspect.

Cause	What you may notice	First fix
Kinked or pinched drain hose	Washer pushed tight against the wall; hose bent behind it	Pull the washer out and straighten the hose
Clogged drain pump filter (front-load)	Water stays in the drum; lint, coins or hair in the filter	Drain and clean the filter
Excess suds	Foam in the drum or door glass	Run Tub Clean; use less HE detergent
Frozen or blocked hose or drain opening	Cold laundry room; water backs up at the standpipe	Thaw with warm water; clear the drain opening
Failed drain pump or control	No hum during Spin Only; OE returns after cleaning	Call LG service

Kinked, pinched or badly placed hose. LG's top-load guide asks you to make sure the hose "is not bent, clogged, or has become pinched between the back of the washer and the wall" ^[2]. LG's top-load error list also names an incorrectly installed hose as a cause ^[3].

Clogged drain pump filter. On front-load models the filter catches lint, coins and small items before they reach the pump. When it clogs, the pump cannot move water.

Too many suds. LG notes that excess suds can create air pockets the drain pump cannot remove, which is enough to trigger OE. This is common when regular detergent goes into a high-efficiency (HE) washer, or when the dose is too large ^[1].

A frozen hose. In unheated garages and basements, the hose can freeze solid. LG's top-load error list names a frozen hose as an OE cause ^[3].

How do you fix the LG washer OE code?

Work from the easiest check to the hardest. Turn the washer off and unplug it before you touch the hose, filter or access panel. If the last cycle was hot, let the water cool before you drain it.

Step 1: Check the drain hose

Pull the washer a few inches away from the wall. Follow the hose from the back of the washer to the standpipe or laundry sink. Straighten any kink, free any section trapped behind the cabinet, and make sure nothing heavy sits on it. LG then suggests running a spin cycle to see whether the code clears ^[1].

If the hose looks fine but you suspect a blockage, LG's top-load list says to lift the hose out of the drain opening and run a spin. If water drains through the hose, the household drain opening may be the clog, not the washer ^[3]. Have a bucket ready before you try this.

Step 2: Run Spin Only and listen

Plug the washer back in and run a Spin Only cycle. On front-load models, LG suggests setting spin to High and listening for a humming sound, which means the drain pump motor has started. LG's next step after hearing the hum is to check the filter, because the pump is running but something is blocking it ^[1]. In our reading, no hum at all suggests a pump or control problem, which is a job for LG service.

Top-load models without a Spin Only option have another route: start a cycle, then pause it. LG says that after 8 minutes the washer times out, shows "dr" and tries to drain ^[2].

Step 3: Clean the pump filter or clear the drain

If the washer still won't drain, unplug it again. On a front-load model, clean the drain pump filter as shown in the next section. On a top-load model there is no filter for owners to open, so clear the hose and the drain opening it empties into, and remove any coins or debris from the hose ^[3].

Step 4: Run an empty test cycle

Plug the washer in and run a short cycle with no laundry. LG's top-load guide uses an empty wash cycle as the final check: if OE comes back, the washer needs repair ^[2].

After it drains: run Tub Clean

If the washer drains during Spin Only, LG recommends a Tub Clean cycle to wash away any buildup that formed while OE was showing ^[2]. On front-load models LG also says to reduce detergent ^[1]. Use HE detergent only.

If the hose froze: thaw it first

If the laundry room was below freezing, remove the laundry and standing water first. LG's top-load list then says to pour warm water of about 122-140 °F (50-60 °C) into the tub and wait 1 to 2 hours, and to wrap a warm, wet cloth around the hose if it is still frozen. LG warns against boiling water because of the burn risk ^[3].

How do you clean the drain pump filter on an LG front-load washer?

The drain pump filter sits behind a small access panel at the lower front of most LG front-load washers; on some models the panel is on the right side of the service cover ^[4]. Expect water to come out, so lay down towels first.

1. Turn the washer off and unplug it. If the door is locked, drain the water through the filter first (steps 2-5); take the laundry out once the door unlocks.
2. Set a shallow pan near the access panel, then open the panel.
3. Pull the small drain tube into the pan, remove its cap and let the water drain. Do not pull the tube too far, because LG says it can kink. Recap it and push it back in.
4. Turn the filter counterclockwise to remove it. A little more water will run out.
5. Remove coins, hair, lint and debris. Rinse the filter by hand with a soft brush or sponge.
6. Turn the filter clockwise until it stops, and close the panel.

LG's steps for draining, removing and refitting the filter come from its filter-cleaning guide ^[4]. A filter that is not screwed in fully can leak, so check for drips on the next cycle. LG also reminds owners to screw the drain tube cap back on securely to prevent leaks ^[1].

If water also stays in the drum and the washer will not spin, our guide to a washer that won't spin covers the overlap between drain and spin problems.

What if the OE code keeps coming back?

If OE returns after you have cleared the hose, cleaned the filter and run an empty cycle, the washer needs a repair. LG says so on its front-load list ^[1] and its top-load guide ^[2]. LG does not name the failed part; in our reading the drain pump, its wiring or the control are the parts left once the drain path is clear.

These are electrical parts inside the cabinet. We do not recommend opening the cabinet or swapping a pump yourself unless you are trained, and never force or defeat the door lock to reach wet laundry. While you wait for service, you can still drain the drum through the filter tube on a front-load model, with the washer unplugged. A top-load model has no filter tube; if Spin Only and the pause-until-"dr" method both fail, remove the laundry and leave the standing water for the technician.

If your washer shows a different code after the drain is fixed, check our pages for the LG UE code (unbalanced load), the LG IE code (water inlet) and the LG LE code (motor). You can browse every LG appliance guide or all washer repair guides.

How can you prevent the OE error?

Because every cause LG lists is a blockage, these habits prevent most repeat codes in our reading.

• Clean the pump filter monthly (front-load). LG recommends cleaning the drain pump filter on a monthly basis, and checking it sooner if draining slows ^[4].
• Use less HE detergent. Follow the dose on the detergent label for your load size, and lean toward less, to keep suds down.
• Protect the hose. Leave a gap between the washer and the wall so the hose cannot pinch, and keep the hose from freezing in cold rooms.

Empty pockets before every load, too. Coins, hair ties and tissue are the debris the filter is designed to catch.
