How to Replace ADQ72912303 Lint Filter on LG Washing Machine — Step-by-Step

Your LG top-load washer is leaving lint all over your freshly washed clothes, or you've noticed water draining slower than usual. Nine times out of ten, it's the lint filter — that small mesh screen working overtime to catch fabric fibers, pet hair, and debris. Models like the WT-H750 and WTG8520 use the ADQ72912303 filter, and replacing it is the easiest maintenance task you'll do all year.

What You Need Before Starting

Here's the good news: you don't need tools for this job. The lint filter on LG top-loaders is designed for tool-free removal and installation. You'll just need:

• Replacement ADQ72912303 lint filter
• Clean towel or rag
• Small brush (old toothbrush works great)
• Bowl of warm water

Time needed: 5-10 minutes
Difficulty: EASY

Safety First

Unplug the washing machine before you start. Even though you're not accessing electrical components, it's smart practice. Also, make sure the washer has finished its cycle and drained completely — you don't want water spilling out when you remove the filter assembly.

Step 1: Locate the Lint Filter Assembly

Open the washer lid. The lint filter is inside the drum, typically attached to the agitator or the center post depending on your model. On the WT-H550 and WT-H650, it's a small mesh basket that sits at the top of the center column. You'll see a circular or rectangular mesh screen — that's what you're replacing.

Step 2: Remove the Old Filter

Grip the filter firmly and pull straight up. Some models have a slight twist-and-lift mechanism, but most just pull out. You might feel some resistance from built-up lint or mineral deposits — that's normal. If it's really stuck, gently wiggle it side to side while pulling upward. Don't force it; gradual pressure works better than yanking.

Step 3: Clean the Filter Housing

With the old filter out, look inside the housing where it sat. You'll probably see accumulated gunk — lint, detergent residue, and hard water buildup. Use your brush and warm water to scrub this area clean. This step matters because a clean housing helps the new filter seal properly and prevents drainage issues. Dry the area with your towel before installing the new filter.

Step 4: Install the ADQ72912303 Filter

Take your new ADQ72912303 filter and align it with the housing. The filter has guides or tabs that match slots in the housing — line them up so it sits flush. Push down firmly until you hear or feel it click into place. Give it a gentle tug upward to confirm it's seated correctly. If it lifts right out, it's not locked in yet.

Step 5: Test the Installation

Plug the washer back in and run a quick rinse cycle without clothes. Watch for any leaks around the filter area during the drain cycle. The water should flow freely through the mesh. If you notice slow drainage or water backing up, remove the filter and reinstall it — it might not be seated properly.

Testing After Installation

After your test cycle completes, open the lid and check the filter again. It should still be firmly in place, not loose or tilted. Run a full wash cycle with a load of towels — they produce plenty of lint. After the cycle, pull out the filter and examine it. You should see lint caught in the mesh, which means it's working correctly. Clean the filter after every few loads to maintain optimal performance.

Frequently Asked Questions

How often should I replace the ADQ72912303 lint filter?

Replace it when you notice the mesh is damaged, torn, or permanently clogged even after cleaning. With normal use, a lint filter can last 2-3 years. However, if you wash a lot of towels, pet bedding, or heavily soiled items, you might need to replace it annually. Clean it every month regardless — that extends its life significantly.

Will this filter fit my LG model if it's not on the compatibility list?

The ADQ72912303 fits most LG top-load washers with a center post agitator design. It replaces the older ADQ72912302 and NEA61973201 part numbers. If your washer is an LG top-loader made between 2010-2020, there's a strong chance it'll fit. Check your owner's manual or compare the old filter's dimensions before ordering. The filter housing design is pretty standardized across LG's top-load lineup.

Can I clean and reuse the old filter instead of replacing it?

You can clean it regularly — in fact, you should. Rinse it under hot water and use a soft brush to remove trapped lint after every few loads. But if the mesh is torn, stretched, or has holes, cleaning won't help. A damaged filter lets lint pass through, defeating its purpose entirely. At under $15, replacing it when it's worn is cheaper than dealing with lint-covered clothes or drainage problems down the road.
