How do you fix an unbalanced LG washer?
On the LG WM1377HW washer, most “unbalanced” problems are fixed by correcting the load (size and distribution) and making sure the washer is solidly level on the floor. If it still bangs or won’t spin after leveling and reloading, the suspension and shock system is the next place to check.
- Pause the cycle, open the door, and redistribute items evenly around the drum.
- Avoid washing a single bulky item (comforter/blanket) by itself; add a few similar items to help balance.
- Avoid very small loads; they can tumble into one heavy clump.
- Reduce spin speed for bulky loads to limit vibration.
- Run a Rinse+Spin test cycle after reloading to confirm the shake is gone.
The WM1377HW can spin up to high speed; even a slight tilt can cause walking, banging, or repeated rebalancing attempts. Follow the leveling steps in the WM1377HW user manual and confirm all four leveling feet are firmly contacting the floor.
- Place a level across the top; check side-to-side and front-to-back.
- Adjust the leveling feet only as much as needed.
- Tighten the locknuts after leveling.
- Re-test with a small load and a spin cycle.
If the washer is level and loads are reasonable but it still shakes hard, the tub support system may be worn.
Common signs you may need service or parts:
- Loud banging even with medium, well-distributed loads
- Excessive tub movement when you push down on the drum by hand (power off)
- Vibration getting worse over time
If you suspect worn dampers, the compatible replacement is the washer shock absorber 383EER3001G.
| What you notice | Most likely cause | Best next step |
|---|---|---|
| Shakes only with bulky items | Load distribution/spin too high | Reload, lower spin |
| Shakes on most loads | Washer not level | Re-level and re-test |
| Banging plus tub “bounce” | Worn shocks/suspension | Inspect shocks, replace if weak |
Running unbalanced loads can shorten the life of the suspension, increase noise, and cause the washer to move out of position, which can stress hoses and wiring.

Is LG a good washing machine to buy?
Yes. LG washers are a strong choice overall, and the LG WM1377HW is built around a high-efficiency front-load design with an inverter direct-drive motor intended for low noise, low vibration, and fewer moving parts. Long-term satisfaction still depends heavily on correct installation, loading, and routine cleaning (see the WM1377HW user manual).
LG front-load washers are popular because they typically balance cleaning performance, efficiency, and features well. For the WM1377HW, the manual highlights several practical design points.
- Inverter direct-drive motor design (fewer moving parts than belt-driven systems)
- High spin speeds (up to 1,400 RPM) to reduce dryer time
- HE detergent design for better rinsing and less oversudsing
- Tub Clean cycle to help prevent detergent residue and musty odors
- Large-capacity stainless steel drum and door-lock safety features
Even a good washer can feel “bad” if it is installed or used in a way that creates vibration, odors, or draining issues.
- Overloading or packing the drum too tightly can reduce cleaning and increase wear
- Using non-HE detergent can cause oversudsing and poor rinsing
- Skipping monthly Tub Clean can lead to odor and residue buildup
- Poor leveling can cause shaking during spin
- Old or kinked hoses can cause fill or leak problems
| Feature | Front-load (like WM1377HW) | Traditional top-load |
|---|---|---|
| Water use | Lower | Higher |
| Cleaning action | Tumble wash | Agitation/impeller |
| Odor risk | Higher if door stays closed | Lower |
| Spin extraction | Typically higher | Typically lower |
A washer is a long-term purchase; choosing a solid platform like the WM1377HW can pay off in lower water use and faster drying. The biggest “make or break” factors are using HE detergent, keeping the door area dry, and keeping the machine level.

How long do LG front loader washing machines last?
LG front-load washers typically last 10 to 15 years with normal household use. For the LG WM1377HW, lifespan is most affected by routine care (especially keeping the door seal and tub clean) and correcting vibration or draining issues early; see the maintenance guidance in the WM1377HW user manual.
- Monthly tub cleaning: This model includes a Tub Clean cycle; running it regularly helps prevent odor and residue buildup.
- Door boot care: Wipe moisture and debris from the door seal area after laundry.
- Proper detergent: Use HE (High-Efficiency) detergent to reduce oversudsing and residue.
- Stable installation: Keeping the washer level reduces wear on suspension and bearings.
- Drain system upkeep: Clearing coins, lint, and debris from the drain path prevents pump strain.
| Task | How often | Why it matters |
|---|---|---|
| Run Tub Clean cycle | Monthly | Reduces buildup that causes odor and component stress |
| Wipe door glass and seal | After use | Helps prevent mildew and leaks |
| Leave door ajar to dry | After use | Reduces moisture that shortens seal life |
| Check hoses for wear/leaks | Every 6 months | Prevents water damage and sudden failures |
| Clean drain pump filter area | As needed | Prevents slow drain and pump overload |
If your WM1377HW is noisy, won’t drain, or won’t unlock, the washer may not be “worn out”; it may need a targeted repair. Common wear items include the drain pump and door lock.
- If the washer won’t drain or drains slowly, inspect the drain path and consider the washer drain pump assembly 4681EA2001T.
- If the door won’t lock/unlock reliably, the LG washer door lock assembly EBF49827801 is a common fix.
- If you see tears, leaks, or mold around the opening, inspect the washer door boot MDS38265303.
A front-load washer can run for years longer when we prevent residue buildup, keep the door area dry, and address early symptoms (vibration, slow drain, door lock issues) before they stress major components like the motor, bearings, and control board.
