LG Washing Machines Repair Manual – Step-by-Step Troubleshooting Guide (2025)
LG washing machines are known for their advanced features, quiet operation, and long-lasting performance. However, like any appliance, they can sometimes malfunction or display errors that require attention. If your LG washer isn't draining, spinning, or starting properly, don’t panic. This repair manual will help you fix the most common problems yourself, without calling a technician.
Note: This guide works for most LG front-load and top-load models, including popular ones like LG WT7150CW, LG WM4000HWA, and LG WM3400CW.
Common LG Washing Machine Problems and Fixes
1. Washer Not Turning On
- ✅ Check the power cord: Make sure it’s plugged in properly and not damaged.
- ✅ Test the outlet: Try plugging another device into the same socket to see if it's working.
- ✅ Reset the washer: Unplug it for 1 minute, then plug it back in and press the Power button.
Still not turning on? The control board or fuse might be faulty—you may need a technician for that.
2. Washer Won’t Drain
- ✅ Check the drain hose: Remove any kinks or clogs.
- ✅ Clean the pump filter: LG front-loaders usually have a filter behind a small front panel.
- ✅ Run the Spin+Drain cycle: This can help force the remaining water out.

3. Washer Not Spinning
- ✅ Uneven load: Open the lid and rearrange the clothes.
- ✅ Lid not locked: Make sure the lid or door is fully closed—LG washers won’t spin otherwise.
- ✅ Check error codes: Look for code “UE” (Unbalanced Error) or “LE” (Motor Error).
4. Strange Noises or Vibrations
- ✅ Level the washer: Use a wrench to adjust the feet so the machine doesn’t wobble.
- ✅ Remove shipping bolts: These must be taken out on new washers before use.
- ✅ Inspect the drum: Check for coins, clips, or other items stuck inside.

LG washers often display error codes on the screen. Here’s what the most common ones mean:
| Error Code | Meaning | Quick Fix |
|---|---|---|
| UE | Unbalanced Load | Rearrange clothes, restart the spin cycle |
| LE | Motor Locked | Unplug, wait 10 mins, try again |
| OE | Drain Error | Check the hose and the pump filter |
| FE | Water Overflow | Check the water inlet valve |
