LG Washing Machine Maintenance Guide
Most LG washers don't ask for much, but they do complain when the basics get ignored. Usually it starts with a musty smell, slower draining, extra shaking on spin, or a small leak that turns into a much bigger headache.
A little regular care makes a real difference. Give the machine some attention now and then, and it will usually run cleaner, quieter, and with fewer surprise repair calls.

Safety Warnings
Unplug the washer and shut off both water supply valves before removing filters, accessing hoses, or cleaning near electrical components. Never force open panels or reach into standing water inside the machine; if you smell burning, see sparking, or find major leaks, stop and call a professional.
Step-by-Step DIY Guide
Take these one at a time. It goes faster that way, and you're less likely to miss the little trouble spots that cause odors, leaks, or poor draining.
Step 1: Disconnect Power and Shut Off Water
Start with the simple part that people rush past. Unplug the washer, close both water supply valves, and pull the machine forward just enough to reach the back and lower front comfortably. You want working room, not a wrestling match with the hoses.
Step 2: Clean the Detergent Dispenser Drawer
Pull the dispenser drawer all the way out. Most LG machines have a release tab, so if it feels stuck, don't force it. Rinse the drawer with warm water, scrub away the sticky detergent and softener film with a soft brush, and dry it before sliding it back in. That buildup gets nasty fast and can leave the washer smelling sour.
Step 3: Wipe the Door Gasket or Lid Opening
This area is a magnet for moisture and grime. On front-load models, peel back the folds of the rubber gasket and wipe out lint, hair, leftover detergent, and any slimy residue with a soft cloth and mild cleaner. On top-load units, clean around the lid opening and rim where splashes and debris settle. Dry the area well when you're done or the mildew will come right back.
Step 4: Run the LG Tub Clean Cycle
With the washer empty, add a washer cleaner tablet or another cleaner approved for your model. Choose Tub Clean if your LG has it. If not, use the hottest cleaning cycle available and let it run all the way through. Even when the drum looks clean, this cycle helps wash out residue and the biofilm that causes that damp, stale odor.
Step 5: Clean the Drain Pump Filter
On most LG front-load washers, you'll find a small access panel near the bottom front of the machine. Put down a towel and a shallow pan first, because there's usually water waiting inside. Drain the hose, remove the pump filter, clear out lint and debris, rinse it clean, and reinstall it securely. If your model doesn't have a user-accessible filter, check the owner's manual before taking anything apart.
Step 6: Check and Clean the Inlet Screens
Once the water is off, unscrew the hot and cold supply hoses from the back of the washer. Look at the small inlet screens inside the valve openings. If you see sediment or mineral buildup, clean them gently with a soft brush or rinse them out. Reconnect the hoses without overtightening. Those tiny screens can cause surprisingly annoying fill problems when they get clogged.
Step 7: Inspect Hoses and Level the Washer
Now give the hoses a close look. Check for bulges, cracks, rust around the fittings, or any sign of seepage, and replace anything questionable before it fails. Then make sure the washer sits solidly on the floor. If it rocks or vibrates harder than usual, adjust the leveling feet and lock them in place. A stable washer runs quieter and puts less strain on the drum and suspension.
When to Call a Pro
- You've done the routine cleaning, but LG error codes like OE, IE, UE, LE, or DE keep showing up.
- Water is leaking from underneath the cabinet or from inside the machine, not just at the hose connections.
- The drum still makes grinding, scraping, or heavy banging noises after you've checked the leveling.
- The washer still won't drain, spin, or power on after you clean the filter, hoses, and dispenser.
