LG Washer OE Error: Drain Problem Fix

The OE error is the most common LG washer error code, indicating the washer cannot drain water from the tub. This guide covers troubleshooting for both front load and top load LG washers, with important differences in filter access.

What Triggers OE

The OE error appears when the washer has been unable to drain for 13 or more minutes. The control board determines that water should have drained by now but the water level sensor still detects water in the tub.

Critical Difference: Front Load vs Top Load

Feature	Front Load	Top Load
Filter Access	Yes—bottom-left behind panel	NO user-accessible filter on most models
Primary Fix	Clean drain pump filter	Check external drain hose
Max Drain Hose Height	96 inches (8 feet)	53 inches (SideKick)

Common Causes (Ranked by Likelihood)

1. Clogged drain pump filter — 60% of cases on front loaders
2. Kinked or obstructed drain hose
3. Drain hose height exceeds maximum
4. Excessive suds creating air pockets
5. Faulty drain pump motor

Front Load Washer: Step-by-Step Fix

Step 1: Power Off and Unplug

1. Press POWER to turn off the washer
2. Unplug from the wall outlet
3. Wait 2 minutes before proceeding

Step 2: Locate the Drain Filter

The drain pump filter is at the bottom-left front of the washer, behind a small access panel or door.

1. Place towels on the floor in front of the washer
2. Open the access panel (press, pull, or use a flathead screwdriver)
3. You’ll see a small emergency drain hose and a larger filter cap

Step 3: Drain Residual Water

There will be water—prepare for it.

1. Place a shallow pan (less than 4” tall) under the filter area
2. Pull out the small emergency drain hose
3. Remove the cap from the hose
4. Let water drain slowly into the pan
5. Empty the pan as needed—there may be several gallons
6. Replace the cap when finished

Step 4: Remove and Clean the Filter

1. Turn the filter cap counter-clockwise
2. Pull the filter straight out (more water may drain)
3. Remove all debris: coins, hair, lint, paper clips, bra underwires
4. Rinse the filter under running water
5. Use a flashlight to inspect inside the pump housing
6. Remove any debris from the housing

Step 5: Reinstall and Test

1. Insert the filter back into the housing
2. Turn clockwise until snug (don’t overtighten)
3. Replace the emergency drain hose cap
4. Close the access panel
5. Plug in the washer
6. Run a SPIN ONLY cycle to test drainage

Listening test: During SPIN ONLY, listen for the pump:

• Humming sound = Pump is working, water should drain
• Complete silence = Pump motor may have failed

Top Load Washer: Troubleshooting

Most LG top load washers have no user-accessible drain pump filter. Focus on these areas:

Check the Drain Hose

1. Pull the washer away from the wall
2. Inspect the entire drain hose for:
   • Kinks or sharp bends
   • Clogs (disconnect and flush with water)
   • Proper height (not exceeding 53” for SideKick models)
3. Ensure the hose end isn’t pushed too far into the standpipe

Verify Drain Hose Height

Maximum heights:

• Standard front load: 96 inches (8 feet)
• SideKick pedestal washer: 53 inches
• Anti-siphon loop minimum: 34-40 inches from floor

If the hose is too high, the pump can’t push water up and out.

Run SPIN ONLY Test

1. Select SPIN ONLY or DRAIN + SPIN cycle
2. Start the cycle
3. Listen for pump operation
4. Check if water drains

Excess Suds Causing OE

Too many suds can create air pockets that prevent proper drainage, triggering OE.

Signs of suds issue:

• Visible foam in drum or around door seal
• Sud/Sd error appeared earlier in the cycle
• Using non-HE detergent

Fix:

1. Run a RINSE + SPIN cycle with no detergent
2. Switch to HE (High Efficiency) detergent
3. Use less detergent than recommended
4. Run Tub Clean cycle
