Sarah Mitchell Key Takeaways
- Run LG's TubClean cycle monthly to prevent mold, mildew, and odors
- Clean the drain pump filter every month — it traps coins, lint, and debris that cause clogs
- Wipe the door boot seal after every wash to prevent mold buildup in front-load models
- Inspect water inlet hoses annually and replace every 5 years to prevent burst-hose flooding
The Bottom Line
Monthly TubClean cycles and drain filter cleaning are the two most important maintenance tasks for any LG washer. These simple habits prevent the most common and costly washer failures.
LG washer maintenance — here's what you need to know.
Regular maintenance keeps your LG washer running efficiently, prevents odors, and avoids expensive repairs. LG has built specific maintenance features into their washers — here's how to use them effectively along with other essential care tasks.
Run TubClean Monthly
LG washers include a dedicated TubClean cycle that runs a high-temperature wash to sanitize the drum and remove detergent residue, mold, and bacteria. Run this cycle once a month without any clothes in the drum. You can add a washing machine cleaner tablet or a cup of white vinegar, but the cycle works effectively on its own. Your LG washer will remind you with a "tCL" indicator when it's time to run TubClean — don't ignore it. Skipping this cycle is the #1 cause of washer odor complaints.
Clean the Drain Pump Filter
The drain pump filter is located behind a small access panel on the front bottom of your LG washer. This filter catches coins, buttons, hair pins, and lint before they reach the pump. A clogged filter causes slow draining, error code OE, and can damage the pump motor. Place a towel and shallow pan under the access panel, unscrew the filter slowly (water will drain out), remove debris, and reinstall. Do this monthly for best results.
Care for the Door Boot Seal
Front-load LG washers have a rubber door gasket (boot seal) that's prone to mold and mildew buildup. After every wash, wipe the inside folds of the gasket with a dry cloth. Monthly, clean the gasket with a solution of equal parts water and white vinegar. Leave the door slightly ajar between washes to allow air circulation. Neglecting gasket care leads to persistent odors and eventually requires a From $80 gasket replacement.
Inspect Water Supply Hoses
Check your washer's hot and cold water supply hoses every 6 months for bulging, cracking, or corrosion at the connections. A burst washer hose can release 500+ gallons of water per hour — it's one of the most common causes of residential water damage. Replace rubber hoses with braided stainless steel hoses, which are far more resistant to bursting. LG recommends replacing hoses every 5 years regardless of appearance.
Use the Right Detergent Amount
LG high-efficiency washers require HE detergent, and most people use too much. Excess detergent creates residue buildup inside the drum and drain system, causing odors and eventually clogging components. Use the amount recommended on the detergent packaging for HE machines — typically 1–2 tablespoons per load. If you see suds through the door window during a cycle, you're using too much detergent.
