How to Keep Your LG Washer Running Well and Lasting Longer

What LG Washers Are Built For and How to Protect Your Investment

LG washers use direct-drive motors and inverter technology to reduce vibration and wear, which means they can handle larger loads and run more quietly than older belt-drive machines. That engineering also means your machine will last longer if you follow a few straightforward maintenance steps. The good news: most of what keeps an LG washer healthy is about cleaning the drum and seals, managing water quality, and catching small problems before they become expensive ones.

Your LG washer manual (usually available as a PDF on LG's support website by model number) will tell you the specific cycle names and settings for your machine, but the maintenance routine is the same across all models. The most important thing you can do is run a cleaning cycle monthly and wipe down the rubber door gasket after every few loads—that's where mold and odor start.

Key Takeaways

• Run LG's TubClean or Tub Clean cycle once a month to prevent mold, odor, and buildup inside the drum.
• Wipe the rubber door gasket dry after each wash, especially in humid climates, because moisture trapped there causes mold within weeks.
• Use the correct amount of detergent—too much leaves residue that traps bacteria and creates smell, and LG washers use less water than older machines.
• Check the drain filter (usually at the bottom front of the machine) every three months and clear any lint, coins, or debris that blocks water flow.
• Hard water and mineral buildup can reduce efficiency, so run a cleaning cycle more often if your water is hard, or use a water softener if buildup is visible.

Running the Cleaning Cycle and Why It Matters

LG washers have a dedicated cleaning program—called TubClean, Tub Clean, or Self Clean depending on your model year—that uses hot water and agitation to dissolve detergent residue, mold spores, and mineral deposits. This cycle takes 30 to 50 minutes and should run once a month, or every two weeks if you wash frequently or live in a humid climate.

To run it: press the power button, select the TubClean or Tub Clean cycle (check your manual for the exact button sequence on your model), and start. Do not add detergent or clothes. If your machine has a Tub Clean+ option, that cycle adds extra heat and is worth using every other month. After the cycle finishes, leave the door open for at least an hour so the drum dries completely.

If you notice a sour smell even after running the cleaning cycle, the gasket may need manual cleaning. Mix one part white vinegar with one part water, soak a cloth in it, and wipe the entire rubber seal—pay special attention to the creases where water pools. Rinse with a damp cloth and dry.

Caring for the Door Gasket and Preventing Mold

The rubber gasket around the door is the most common place mold grows in front-load washers because water and detergent residue get trapped in the folds. LG gaskets are designed to shed water, but they only work if you help them dry. After every wash—or at least after every third wash—open the door and wipe the gasket with a dry cloth, paying attention to the creases on the underside.

In humid climates or if you run back-to-back loads, leave the door open between washes. This takes 30 seconds and prevents the warm, wet environment where mold thrives. If mold has already started (you'll see black or pink spots), soak a cloth in white vinegar, tuck it into the gasket creases, and let it sit for 15 minutes. Then wipe thoroughly and run a TubClean cycle.

If the gasket smells even after cleaning, or if you see mold that won't come off, the gasket may need to be replaced. LG gaskets are available through the manufacturer's parts website or through appliance parts retailers. Replacement takes 10 to 15 minutes and costs between $50 and $150 depending on your model.

Using the Right Amount of Detergent

LG washers use significantly less water than traditional top-load machines, which means detergent concentrates more in the drum. Using the amount you would use in an older washer will leave residue, trap bacteria, and create odor. Start with half the amount the detergent bottle recommends, and adjust only if clothes don't come clean.

High-efficiency (HE) detergent is designed for LG washers and produces fewer suds, which means the machine can rinse more effectively. If you use regular detergent, you may need to run an extra rinse cycle to remove all the soap. Check your manual for the rinse options available on your model—many LG washers have a Extra Rinse or Rinse+ setting.

Liquid detergent dissolves faster than powder in cold water, which is useful if you wash in cold cycles. Powder detergent works well in hot water but can leave visible residue if the water is too cold. If you notice white or colored streaks on clothes after washing, you're likely using too much detergent or the water temperature is too low for the type you're using.

Checking and Clearing the Drain Filter

LG washers have a drain filter (also called a lint trap) that catches coins, buttons, lint, and other debris before they reach the pump. If this filter clogs, water drains slowly or not at all, and the machine may display an error code. Check it every three months, or immediately if you notice water pooling at the bottom of the drum after a cycle.

The filter is usually located behind a small panel at the bottom front of the machine. To access it: turn off and unplug the washer, open the panel (it may be held by a clip or screw), and slowly unscrew the filter cap by turning it counterclockwise. Water will spill out, so place a towel underneath. Empty any debris, rinse the filter under running water, and screw it back in hand-tight—do not over-tighten.

If water won't drain at all, the filter may be severely clogged or the drain hose may be kinked. Check that the hose behind the washer is not bent or pinched. If the hose is clear and the filter is empty, the pump itself may be blocked—this requires a service call.

Managing Hard Water and Mineral Buildup

Hard water (water with high levels of calcium and magnesium) leaves white or chalky deposits inside the drum and on clothes. If you have hard water, you'll notice this buildup within a few months. The TubClean cycle helps, but running it every two weeks instead of monthly will keep buildup minimal.

A second option is to add a water softener to your home's main water line, which removes minerals before water reaches the washer. This is a larger investment but solves the problem for all appliances. A third option is to use a commercial descaling product designed for washers—follow the product instructions and run a cleaning cycle afterward.

If you see white deposits on clothes or inside the drum, soak the affected clothes in white vinegar and water (one part vinegar to three parts water) for 30 minutes, then wash again. For the drum, run a TubClean cycle with a commercial washer descaler, or use white vinegar in place of detergent on a hot water cycle.

Understanding Error Codes and When to Call for Service

LG washers display error codes on the control panel when something is wrong. Common codes include dE or dL (door lock problem), oE (overflow), uE (unbalanced load), and IE (inlet valve problem). Your manual will list all codes specific to your model. Many codes can be fixed by stopping the cycle, checking for obvious problems (like a twisted hose or an overloaded drum), and restarting.

If an error code appears repeatedly, or if the washer won't drain, won't fill, or makes unusual noises, contact LG support or a local appliance repair service. LG's support website has a parts locator and a service request tool. Keep your model number (usually on a sticker inside the door frame) and your purchase date handy when you call.

Frequently Asked Questions

How often should I run the TubClean cycle?

Run it once a month for normal use, or every two weeks if you wash frequently, live in a humid climate, or notice odor. If you use cold water for most loads, run it every three weeks because cold water doesn't dissolve detergent residue as well as hot water.

Can I use regular detergent in my LG washer?

You can, but it's not ideal. Regular detergent produces more suds than HE detergent, and LG washers use less water to rinse them out. If you use regular detergent, use half the recommended amount and run an extra rinse cycle. HE detergent is cheaper over time and works better.

What does it mean if my washer smells bad even after cleaning?

The gasket is the most likely culprit. Wipe it thoroughly with vinegar and water, especially the creases underneath. If the smell persists after cleaning and running a TubClean cycle, the gasket may need to be replaced, or mold may be growing inside the pump or drain hose—contact a repair service.

Why is water pooling at the bottom of my drum?

The drain filter is probably clogged. Check it first by opening the panel at the bottom front and clearing any debris. If the filter is clean and water still won't drain, the drain hose may be kinked or the pump may be blocked—check the hose first, then call for service if that doesn't solve it.

Is it normal for my LG washer to be quiet?

Yes. LG's direct-drive motor and inverter technology are designed to run quietly. If your washer suddenly becomes very loud or makes grinding or squealing sounds, something may be wrong—contact support or a repair service.
