LG Washer Not Draining Completely — What’s Happening
When an LG front-load washer does not drain completely, water remains in the tub at the end of the cycle. LG defines this as a drain failure, meaning the machine cannot remove water from the tub within the expected time. The symptom is typically tied to a blocked or restricted drain path, a clogged pump filter, or a failed drain pump. LG front-load models display an OE error code when this drainage failure occurs, though the underlying issue is the same whether or not the code appears on your control panel.
Most Likely Causes
- Kinked, bent, or twisted drain hose A drain hose pinched behind the washer or bent sharply at a connection point restricts water flow and is the most common cause of incomplete draining.
- Clogged drain pump filter Lint, coins, small clothing items, and other debris accumulate in the pump filter over time and block water from reaching the pump.
- Blocked drain pump impeller or failed pump motor Debris jams the pump impeller, or the pump motor itself fails and can no longer move water out of the tub.
- House drain line blockage A clog or restriction in your standpipe or home drain line downstream of the washer prevents water from leaving the machine, even if the washer’s own drain system is clear.
- Frozen drain hose In unheated laundry rooms or garages, the drain hose can freeze in cold weather and block water flow completely.
- Drain hose installed too high LG specifies the drain hose should not be installed higher than 6 cm from the floor at the washer end, or gravity cannot assist proper drainage.
How to Diagnose and Fix
- Inspect the drain hose along its entire length for kinks, sharp bends, or any point where the hose is compressed or twisted.
- Pull the drain hose out of the standpipe or drain connection and place the end in a bucket, then run a Spin Only cycle (press Power, select High spin) to see if water exits the hose freely.
- If water drains freely into the bucket, the blockage is in your house drain line, not the washer.
- Open the pump filter access panel at the front lower corner of the washer, place towels on the floor, and slowly unscrew the filter cap to drain residual water and remove trapped debris.
- Clean the pump filter thoroughly, check the filter cavity for coins or foreign objects, then reinstall the filter and tighten the cap securely.
- Run another Spin Only test and listen for the drain pump to hum or run during the first 15 seconds of the cycle.
- If the pump hums but no water moves, remove the pump from the cabinet and inspect the impeller for debris or a broken blade.
- If the pump is silent and the hose and filter are clear, measure for supply voltage at the pump terminals during a drain command to confirm the control board is sending power to the pump.

When to Call a Pro
Call a technician if you have cleared the hose and filter but the pump still does not run, or if the pump hums continuously without moving water and you cannot access or remove the pump assembly yourself. Diagnosing control board voltage and replacing the pump often require disassembly of the front panel and cabinet, and mistakes during reinstallation can cause leaks or further electrical faults.
