This is one of the most common issues LG washing machine owners face, and in most cases, it's something you can diagnose and fix at home in under 30 minutes. This guide walks you through every cause and every fix, so you can stop asking "why won't my lg washer won't drain" and get back to clean laundry fast.
LG Washer Won't Drain: Causes & Quick Fixes at a Glance
Why Does an LG Washer Won't Drain Issue Happen?
When your lg washer won't drain, it almost always points to one thing: something is preventing water from leaving the drum. The issue can be as simple as a clogged filter or as involved as a failed pump motor. Understanding the root cause is the fastest path to a fix.
The lg washer won't drain problem typically shows up in one of two ways — either the machine stops mid-cycle and displays an OE error code, or it completes the cycle but leaves water sitting in the drum. Both point to the same underlying drainage failure. Either way, an lg washer won't drain situation needs to be addressed promptly to avoid further damage.
How to Fix an LG Washer That Won't Drain: Step-by-Step
Step 1: Run a Spin Only Cycle
The first thing to try when your lg washer won't drain is running a dedicated Spin Only cycle. Cancel the current program, select Spin Only, and press Start. If the lg washer won't drain issue is caused by excess suds or a temporary sensor glitch, this cycle will often clear it on its own.
If the drum still has standing water afterward, move to Step 2.
Step 2: Clean the Drain Filter
A clogged drain filter is the number one reason an lg washer won't drain. Lint, hair, coins, and small clothing items accumulate in the filter over time and eventually block water from flowing out.
The filter is located at the bottom front of most LG washers, behind a small access panel.
How to clean it:
Place a shallow tray and towels under the access panel to catch water
Open the panel and pull out the small emergency drain hose — remove the cap and let residual water drain out
Turn the filter cap counter-clockwise and pull it out
Remove all lint, hair, coins, and debris from the filter and housing
Rinse the filter under running water until clean
Reinsert, tighten the cap, and close the panel
Run a short test cycle to confirm your lg washer won't drain error is gone
Pro tip: Clean the drain filter at least once a month. This single habit eliminates the majority of lg washer not draining issues before they happen. For a broader look at drainage problems across washer brands, check our guide on washing machine not draining.
Step 3: Inspect the Drain Hose
If the filter is clean but your lg washer won't drain, the drain hose is the next place to look.
Pull the washer away from the wall and check the entire hose for kinks or sharp bends
Detach the hose from the standpipe or utility sink and inspect inside for blockages
Make sure the hose is installed at the correct height — LG recommends between 6 cm and 96 cm from the floor
Check that the hose isn't inserted too deeply into the standpipe, which can create a siphon effect and cause your lg washer won't drain fault to keep returning
If the hose is cracked, brittle, or deformed, replace it. A damaged hose is a common overlooked cause of the lg washer water not draining problem.
Step 4: Check the Drain Pump
If you've cleaned the filter and checked the hose but your lg washer won't drain, the pump may be the culprit. The drain pump is responsible for physically pushing water out of the machine — if it's jammed or failing, your lg washer won't drain no matter what else you try.
Signs of a pump problem:
Loud humming or buzzing noise when the machine tries to drain
Water drains very slowly or not at all
OE error code appears immediately when the drain phase begins
To inspect the pump:
Unplug the washer completely
Remove the back or bottom access panel (varies by LG model)
Locate the drain pump at the base of the machine
Check the impeller blades for trapped objects and clear any debris by hand
Reconnect and run a test cycle
If the pump motor is burnt out or seized, it needs professional replacement. See our detailed breakdown of lg washer drain pump replacement for costs, signs, and when to call a tech.
Step 5: Check for LG ThinQ App or Software Issues
If you have an lg thinq washer not draining, a software or connectivity glitch may be causing your lg washer won't drain problem — especially after a firmware update.
Try the following:
Open the LG ThinQ app and check for any error notifications or pending updates
Run a diagnostic cycle directly through the app to identify the fault
If the app shows no issues, power cycle the washer: unplug for 5 minutes, then restart
ThinQ-connected models can sometimes get stuck in a fault state after a software hiccup. A full reset usually resolves the lg washer won't drain issue without any physical intervention.
Step 6: Reset the Washer
After addressing the physical cause, reset the machine to clear any fault codes stored in the control board:
Turn the washer off and unplug from the outlet
Wait a full 5 minutes
Plug back in and run a short wash cycle to confirm your lg washer won't drain error no longer appears
This step is essential even after cleaning the filter or hose — the control board needs a reset to recognize that the fault has been resolved. If the my lg washer is not draining problem returns after the reset, it's time to call a professional.
LG Washer Won't Drain: Front-Load vs. Top-Load
Front-Load LG Washers
Front-loaders are the most prone to the lg washer won't drain issue. Because the drum sits horizontally, the pump handles 100% of the drainage work with no gravity assist. A partially clogged filter or weak pump causes your lg washer won't drain problem to surface much sooner in front-loaders than in top-load models. Monthly filter maintenance is non-negotiable.
Top-Load LG Washers
On top-loaders, gravity assists drainage, so the system is slightly more tolerant of partial blockages. However, lg washing machine not draining on a top-loader is usually caused by drain hose positioning or a foreign object lodged in the pump — not the filter. Start with the hose inspection and pump check on these models.
