# How to Fix LG Error OE (Drain Error)
The LG washing machine error code **OE** (which stands for Water **O**utput **E**rror) is a common indication that the machine has failed to successfully drain water from the drum within the specified time limit (usually 5 to 10 minutes, depending on the model).
While often a sign that the main **Drain Pump** is failing, the vast majority of OE errors are actually caused by a simple blockage.

## Explanation: What Error OE Means
If your LG washer displays the OE code, it means the water level sensor still detects water in the drum after the drain cycle has finished.
**The two most likely causes are:**
1. **Blockage:** Debris (coins, socks, lint) has clogged the drain filter or the pump impeller.
2. **Pump Failure:** The drain pump is worn out, not receiving power, or has completely failed.

## Step-by-Step Fix: How to Diagnose and Clear the OE Error
Before performing any physical inspection, you **MUST** ensure the machine is completely disconnected from power.
### Step 1: Safety & Preparation
1. **Unplug the Machine:** Locate the power cord and disconnect the washer from the wall outlet.
2. **Turn Off Water:** Shut off both the hot and cold water supply valves connected to the back of the washer.
3. **Position for Water:** Place towels and a shallow basin near the front bottom of the machine, as water will leak out during this process.
### Step 2: Check the Drain Hose (External Blockage)
Often the simplest fix.
1. **Check for Kinks:** Inspect the entire length of the drain hose, ensuring it is not severely bent or kinked where it enters the standpipe or sink.
2. **Check the Standpipe:** Verify that the end of the drain hose is not pushed too far down into the standpipe (if using one). If it is too deep, the hose can siphon water back into the drum, confusing the sensors.
3. **Clear the Connection:** If draining into a sink, ensure the sink’s drain is not blocked.
### Step 3: Clean the Drain Pump Filter (Internal Blockage)
This is the most common source of the OE error. The filter traps foreign objects before they can reach the pump impeller.
1. **Locate the Access Panel:** On most LG front-load washers, the drain filter is located behind a small square or rectangular panel at the bottom-front of the machine. Open this panel (you may need a flathead screwdriver).
2. **Drain the Remaining Water:** You will see a small rubber hose or cap. Remove the cap or unscrew the plug to drain the remaining water into your basin.
3. **Remove the Filter:** Once the water is drained, carefully unscrew the large circular filter plug (turn counter-clockwise).
4. **Inspect and Clean:** Remove any trapped items (coins, lint, hair, paperclips, etc.) from the filter and the filter housing cavity. Rinse the filter thoroughly under a sink.
5. **Check the Impeller:** Using a flashlight, look into the cavity where the filter screws in. You should be able to see the **impeller** (a small fan or propeller). Push it gently with your finger—it should turn freely. If it is stiff or stuck, there is a large blockage lodged directly in the pump.
6. **Reassemble:** Screw the clean filter back in tightly, replace the drainage cap/plug, and close the access panel.
### Step 4: Test the Drain Pump (Advanced Diagnosis)
If the filter is perfectly clean and the error persists, the drain pump itself is the likely culprit.
1. **Locate the Pump:** The drain pump is usually located just behind the drain filter access panel. You may need to tilt the machine back or remove the front lower panel to fully access it.
2. **Check Connections:** Ensure the wiring harness attached to the pump motor is securely fastened. Loose connections can mimic a failed pump.
3. **Check for Continuity (Optional):** If you own a multimeter, disconnect the wiring harness and check the pump motor terminals for continuity. If the motor shows no continuity (infinite resistance), the pump is electrically dead and requires replacement.
### Step 5: Final Test
Plug the machine back in and run a short **Rinse & Spin** cycle. If the machine drains successfully, the OE error should be gone. If the error returns, the drain pump motor must be replaced.

**Replacement Part Recommendation**
If you have confirmed that the drain filter is clean, the hose is clear, and the pump impeller is stuck or the motor is dead, the unit requires a new drain pump assembly.
