LG Washing Machine Wi-Fi Troubleshooting: Fix Connection & App Errors

Smart home appliances make laundry simpler, but Wi-Fi issues can cause frustration. If your LG washing machine Wi-Fi connection fails or the LG ThinQ app shows errors, don’t panic. This guide explains how to fix connection and app problems quickly.

Why LG Washing Machines Use Wi-Fi

Wi-Fi allows your LG washing machine to connect with the LG ThinQ app. You can:

• Start or stop cycles remotely.
• Get notifications when a load finishes.
• Monitor energy use and water consumption.
• Download specialized washing cycles.

According to Statista (2025), over 65% of homeowners prefer appliances with Wi-Fi connectivity. Therefore, knowing how to fix app and connection errors saves time and avoids repair costs.

Common LG Washing Machine Wi-Fi Connection Issues

Most Wi-Fi problems fall into predictable categories. Here are the most common:

1. Incorrect Wi-Fi frequency: LG washers connect only to 2.4 GHz networks, not 5 GHz.
2. Weak router signal: Poor placement reduces connectivity.
3. App glitches: Outdated ThinQ app versions may cause errors.
4. Washer firmware issues: Old software blocks a smooth connection.
5. Router settings: Disabled DHCP or a hidden SSID interferes with setup.

Step-by-Step LG Washing Machine Wi-Fi Troubleshooting

1. Check Your Wi-Fi Network

• Ensure the router broadcasts at 2.4 GHz.
• Keep the washer within 30 feet of the router.
• Restart your modem and router.

2. Update the LG ThinQ App

• Go to the Google Play Store or Apple App Store.
• Install the latest update.
• Clear the app cache if errors persist.

3. Reset the Washer’s Wi-Fi Settings

• Press and hold the Wi-Fi button on the control panel for 3 seconds.
• Wait until the Wi-Fi icon blinks.
• Reconnect using the ThinQ app.

4. Verify Router Settings

• Enable DHCP for automatic IP assignment.
• Keep the SSID visible (don’t hide the network name).
• Ensure the router allows at least WPA2 security.

5. Reinstall the LG ThinQ App (if needed)

• Delete and reinstall the app.
• Re-add your washer during setup.

LG ThinQ App Error Codes and Fixes

• Error Code 001: Incorrect Wi-Fi password → Re-enter password.
• Error Code 002: No network detected → Restart router.
• Error Code 005: Connection timed out → Move washer closer.
• Error Code 007: Server issue → Try again later or reinstall the app.

When to Update Your Washer’s Firmware

LG regularly releases firmware updates for smart washers. Updated software improves Wi-Fi stability and energy efficiency.

Steps:

1. Open the ThinQ app.
2. Go to Settings > Update Firmware.
3. Keep the washer powered on during updates.

According to Energy Star, newer software versions can reduce appliance energy waste by 10–15%.

Practical Tips for Stronger Wi-Fi Performance

• Place your router on an open shelf, not behind walls.
• Limit interference from microwaves or cordless phones.
• Use a Wi-Fi extender if your laundry room is far from the router.

Personal Suggestion: If you live in a small apartment, a Wi-Fi extender may be unnecessary. But for larger homes, especially two-story houses, an extender ensures smooth app performance.

Repair vs DIY Fix

If troubleshooting doesn’t work, you may need professional repair. However, most Wi-Fi connection issues resolve with simple resets. Hiring a technician should be the last option.

Before calling for service, check:

• Router functionality.
• App updates.
• Washer’s Wi-Fi icon status.

If the icon stays off despite resets, you may face a Wi-Fi module failure, which requires service.
