Understanding Lg Thinq Washer Features

Some unique features include:
- Smart Diagnosis: Sends washer status and error info to LG support.
- Remote Start: Begin washing from your phone.
- Energy Monitoring: Track water and electricity use.
- Auto Dose: Controls detergent quantity automatically.
Many problems are related to these features, so understanding them helps you identify issues more easily.

Common Lg Thinq Washer Problems And How To Fix Them
LG ThinQ washers are reliable, but like any appliance, they can develop issues. Here are the most frequent problems and how to solve them.
1. Washer Not Starting
If your washer won’t start, check these areas:
- Power supply: Confirm the outlet works. Plug another device in to test.
- Door lock: Make sure the door is fully closed. A loose door prevents starting.
- Child lock: Some models have a child lock (CL). Disable it by holding the appropriate button for 3 seconds.
- Control panel: If unresponsive, unplug the washer for 60 seconds, then reconnect.
If these steps don’t help, check for error codes on the display.
2. Water Not Draining
A common frustration is water left inside after a cycle. Here’s what to do:
- Check drain hose: Ensure it’s not kinked or blocked.
- Clean drain filter: Open the lower panel, remove the filter, and clear debris.
- Run a drain cycle: Select ‘Drain & Spin’ on the control panel.
- Pump failure: If you hear a humming noise but no draining, the pump may be clogged or faulty.
Don’t forget to place a towel under the filter—many users miss this and spill water everywhere.
3. Washer Not Spinning
If your clothes are still wet, the spin cycle may not be working:
- Load balance: Too many or too few items can cause imbalance. Rearrange laundry and try again.
- Drain issue: If water isn’t draining, spinning won’t start.
- Error codes: Look for codes like UE (unbalanced load) or LE (motor error).
Try running an empty spin cycle. If it works, your load was likely unbalanced.
4. Strange Noises
LG ThinQ washers are usually quiet. Noises can indicate:
- Foreign objects: Coins or buttons stuck in the drum or filter.
- Loose drum: If the drum wobbles, check for worn bearings.
- Pump noise: A loud humming often means debris in the pump.
Remove items from pockets before washing—many forget, leading to noise and damage.
5. Error Codes Explained
LG ThinQ washers display error codes to guide troubleshooting. Here are the most common:
| Error Code | Meaning | Quick Solution |
|---|---|---|
| IE | Water Inlet Error | Check water supply and inlet hose |
| OE | Drain Error | Clean drain filter and check hose |
| UE | Unbalanced Load | Redistribute laundry |
| LE | Motor Error | Reset washer, check for overload |
| PE | Pressure Sensor Error | Restart washer, check water level |
| CL | Child Lock | Hold child lock button to disable |
If you see a code not listed, consult your manual or the ThinQ app for details.
Step-by-step Troubleshooting Guide
Let’s walk through the most common fixes in detail.
Checking Power And Connectivity
- Unplug and Replug: Sometimes, resetting the washer solves minor glitches.
- Circuit Breaker: Make sure the breaker hasn’t tripped.
- Wi-Fi Connection: If using ThinQ app, check that your washer is connected. Reconnect via the app if necessary.
Cleaning The Drain Filter
This simple step solves many problems:
- Open the access panel at the washer’s bottom front.
- Place a tray or towel under the filter.
- Unscrew the filter slowly, letting water drain.
- Remove debris, rinse filter, and replace.
Many users skip regular filter cleaning, leading to drainage issues. Clean monthly for best results.
Resolving Water Supply Issues
- Ensure the water faucets are fully open.
- Check hoses for bends or clogs.
- Clean inlet screens (filters inside hose connection).
- If water flow is weak, replace hoses or call a plumber.
Fixing Unbalanced Loads
- Remove some items if overloaded.
- Add towels to small loads for balance.
- Avoid washing only heavy items (like a single blanket).
If unbalanced load errors persist, the suspension system may need repair.
Dealing With Connectivity And App Errors
LG ThinQ relies on Wi-Fi. If remote functions don’t work:
- Restart your router.
- Reconnect washer in the ThinQ app.
- Update the app for bug fixes.
Some homes have Wi-Fi dead spots—move your router closer if you lose connection often.
Resetting The Washer
To reset:
- Unplug washer.
- Wait at least 60 seconds.
- Plug back in and power on.
This resets internal electronics and can clear minor errors.
Regular Maintenance Tips
Preventing issues is better than fixing them. Here’s how to keep your LG ThinQ washer running smoothly:
Cleaning And Care
- Drum cleaning: Run the ‘Tub Clean’ cycle monthly with no laundry, using washer cleaner.
- Door gasket: Wipe rubber seal after each use to prevent mold.
- Detergent drawer: Remove and clean every few weeks.
- Ventilation: Leave the door open between washes to air out the drum.
Water And Detergent Management
- Use HE detergent (high efficiency) for front-loaders.
- Avoid overdosing—ThinQ’s auto dose helps, but check levels regularly.
- Hard water can cause buildup; use a washing machine cleaner if you notice residue.
Checking Smart Features
- Update ThinQ app regularly.
- If Smart Diagnosis isn’t working, check your phone’s Bluetooth and Wi-Fi.
Monitoring Performance
- If cycles seem longer than usual, check for clogs or slow water supply.
- If clothes aren’t clean, try a different cycle or increase detergent slightly.
Advanced Troubleshooting: When To Call A Professional
Some issues require expert help. Here’s how to tell:
- Repeated error codes: If resetting doesn’t fix recurring codes, parts may need replacement.
- Leaks: Water leaking from underneath often means a damaged hose or seal.
- Electrical smells: Stop using immediately—could indicate wiring problems.
- Drum not turning at all: Motor or belt failure needs professional repair.
LG offers Smart Diagnosis—use the ThinQ app to send error info directly to support.

Non-obvious Insights For Lg Thinq Washer Owners

Frequently Asked Questions
What Does The Ie Error Mean On My Lg Thinq Washer?
The IE error stands for ‘Water Inlet Error’. It means your washer isn’t getting enough water. Check that faucets are fully open, hoses aren’t kinked, and the inlet filter is clean. If the problem continues, water pressure may be too low, or the inlet valve may need replacing.
How Often Should I Clean The Drain Filter?
You should clean the drain filter at least once a month. If you wash items with lots of lint or small objects, clean it more often. Regular cleaning prevents drainage issues and helps your washer last longer.
Can I Use Regular Detergent In My Lg Thinq Washer?
Always use HE detergent for LG ThinQ front-load washers. Regular detergent can cause excess suds, poor cleaning, and even damage. The ThinQ auto dose feature helps manage the right amount, but check your detergent type before using.
How Do I Reset My Lg Thinq Washer?
To reset your washer, unplug it from the wall and wait 60 seconds. Plug it back in, then press and hold the Start/Pause button for 5 seconds. This resets the washer’s electronics and clears many minor errors.
Is It Normal For My Washer To Make Noise During Spinning?
Some noise is normal, especially during spinning. However, loud banging, grinding, or rattling can mean an unbalanced load, loose parts, or foreign objects in the drum. Stop the cycle, check inside, and redistribute laundry to reduce noise.

Troubleshooting your LG ThinQ washer doesn’t need to be stressful. With the right knowledge, most problems are easy to fix at home. Start by checking basic issues like power, water supply, and filter cleanliness. Use the ThinQ app for error codes and remote diagnostics.
