How to Clean Your LG Washing Machine: The 2026 Master Guide
Step-by-step instructions to remove smells, mold, and buildup from front & Top Load LG washers.
Technician's Insight: Most LG owners wait until their clothes smell like sour milk before cleaning their machine. By then, bacteria had already formed a biofilm behind the drum. In 2026, with AI-driven machines, keeping the sensors clean is essential for the machine to weigh your laundry correctly. Let's get it cleaned the right way.

Phase 1: Deep Cleaning
Phase 2: Filters & Logic
1. Using the LG Tub Clean Feature Correctly
Every modern LG washer has a dedicated **tub clean** cycle. This isn't just a regular wash; it uses higher water levels and extreme temperatures to break down detergent scum.
- Frequency: Run this cycle once a month or every 30 wash loads.
- Step 1: Ensure the drum is completely empty.
- Step 2: Add your cleaner (see section below) directly into the drum or the main wash compartment.
- Step 3: Select 'Tub Clean' on the dial and press Start.
2. Vinegar, Bleach, or Tablets? (The 2026 Verdict)
In 2026, LG's AI DD technology uses sensitive rubber components. Here is what you should use:
| Cleaner | Rating | Reason |
|---|---|---|
| Affresh / LG Tablets | Best | Slow-dissolving; reaches behind the drum. |
| Liquid Bleach | Good | Kills mold and bacteria instantly. |
| White Vinegar | Avoid | Can degrade rubber seals over time. |
3. The Rubber Gasket: The #1 Source of Odors
If you have an LG front loader, the grey rubber seal (gasket) at the front is where mold lives. Water gets trapped in the folds.
- Mix 1 cup of bleach with 1 quart of warm water.
- Pull back the folds of the rubber seal and wipe inside with a microfiber cloth.
- The Secret Spot: Look for the small drain holes at the bottom of the seal. Use a toothbrush to clear any hair or lint blocking them.
- Leave the door open for 2 hours to air dry.

4. Cleaning the ezDispense Drawer
LG's auto-detergent system can become clogged with gooey old soap. To clean it:
- Remove the drawer by pressing the release button in the center.
- Rinse it under warm running water. Do not use harsh chemicals here.
- Wipe the inside of the drawer cavity in the machine; this is a hidden spot for black mold.
5. The Drain Pump Filter (Front Load Focus)
If your LG washer isn't draining properly or smells like stagnant water, the drain pump filter is likely clogged. This small filter catches coins, hair, and lint.
- Open the small cover at the bottom front of the machine.
- Pull out the small rubber hose and drain the excess water into a bowl.
- Unscrew the large plastic filter (turn counter clockwise).
- Rinse the filter under warm water and remove any debris. Pro Tip: Use a flashlight to check inside the pump housing for trapped coins.
6. Cleaning the 2026 Microplastic Filter
Newer 2026 LG models come with a built-in microplastic filter to protect the environment. Unlike the drain filter, this needs gentle handling.
- Locate the filter cartridge (usually near the water inlet or detergent drawer).
- Pull it out and use a soft brush to remove the fine microfibers.
- Do not use soap; just plain water is enough to keep the mesh clear.
7. LG Maintenance Master Schedule
To keep your machine running for 10+ years, follow this simple routine:
| Task | Frequency | Benefit |
|---|---|---|
| Wipe the door gasket. | After Every Wash | Prevents Mold & Odors |
| Clean Detergent Drawer | Weekly | Stops Clogs |
| Run Tub Clean Cycle | Monthly | Removes Biofilm |
| Drain Pump Filter | Every 3 Months | Prevents OE Errors |
Common LG Cleaning Questions
Q: Why does my LG washer still smell after a tub clean?
A: This usually happens because mold is trapped in the drain pump filter or the rubber door gasket. A Tub Clean cycle cleans the drum, but you must clean the filters and gasket manually.
Q: Can I use dishwasher tablets to clean my LG washer?
A: It is not recommended. Dishwasher tablets create too much foam (suds) for a washing machine, which can damage the sensors and the motor.
Q: How do I get rid of the tcL code on my display?
A: tcL stands for Tub Clean. It is a reminder, not an error. Simply run the Tub Clean cycle with a cleaner, and the code will disappear automatically.
