Modern washing machines LG with support Wi-Fi Open up new possibilities: remotely starting a wash cycle, monitoring its status, automatically updating programs, and even troubleshooting problems via a smartphone. But to take advantage of these features, you first need to properly connect the appliance to your home network. In this article, we'll walk you through the process step by step—from checking model compatibility to resolving common connection issues.
It is important to understand that the procedure may vary depending on washing machine models (for example, LG F4V9RWP2W vs LG WT7300CW), firmware version, and router type. We'll look at a universal algorithm that's suitable for most devices. LG with module Wi-FiWe'll also point out key points where details may vary. If your car was manufactured before 2018, check its specifications—it may not support wireless connectivity.
Before you begin, make sure you have the following on hand: smartphone (Android/iOS) with the app installed LG ThinQ, login details Wi-Fi network (name and password), as well as access to router in case you need to change the settings (for example, switch the frequency from 5 GHz to 2.4 GHz).
1. Checking the compatibility of your LG washing machine with Wi-Fi
Not all washing machines LG equipped with a module Wi-FiTo avoid disappointment, first make sure your model supports network connectivity. Here's how:
- 🔍 Look at the body of the car: modern models with support Wi-Fi usually have a corresponding logo (for example, Smart ThinQ or Wi-Fi Ready) on the front panel or sticker.
- 📄 Review the documentation: The operating instructions or the box should contain information about the functions Smart Diagnosis or Remote Control.
- 🌐 Check on the LG website: Enter the car model in the search on the official website - the availability of the module will be indicated in the specifications Wi-Fi (look for sections
Smart functionsorConnection).
If your car was made after 2019, it most likely supports Wi-FiFor 2017-2018 models (e.g. LG FH4U1JBH2N or LG T2455VS2ML) additional may be required Wi-Fi adapter, which is purchased separately. Check with the manufacturer or service center.
⚠️ Attention: Some washing machines LG with function Smart Diagnosis (for example, via NFC) do not support full connection to Wi-FiThey can only send error data to a smartphone, but do not allow remote control of the washing machine.
| Model range | Wi-Fi support | Do you need an adapter? | Notes |
|---|---|---|---|
| LG FH4U1JBH2N, LG F4V9RWP2W (2020–2026) | Yes | No | Built-in module, supports ThinQ |
| LG WT7300CW, LG WM3900HWA (2018–2019) | Yes | Sometimes | An adapter may be required LG SmartThinQ Wi-Fi Dongle |
| LG FH2G6TDH2N, LG T2455VS2ML (until 2017) | Partially | Yes | Only Smart Diagnosis via NFC |
2. Preparing the router for connecting the washing machine
Washing machines LG usually only work with networks 2.4 GHzIf your router broadcasts two frequencies (2.4 and 5 GHz) under the same name, your device may not see the network. Here's what to do:
- 📶 Divide the networks: go to the router settings (usually at the address
192.168.0.1or192.168.1.1) and disable the functionSmart ConnectorBand Steering. Create separate names for 2.4 GHz and 5 GHz (e.g.MyWiFi_2GAndMyWiFi_5G). - 🔒 Check the encryption type: car LG supports only
WPA2-PSK (AES)If you haveWPA3orWEP, change security settings. - 📡 Make sure the signal is stable: The washing machine must be in a strong reception area. If the signal is weak, use repeater or move the router closer.
Also check if it is enabled on the router MAC address filter or guest mode — they can block new devices from connecting. If you're unsure of the settings, temporarily disable the password on the 2.4 GHz network (but don't leave it open for long!).
⚠️ Attention: If your router only supports 5 GHz (for example, some models from providers), you will need to purchase a separate 2.4 GHz router or access point. Washing machines LG do not work at 5 GHz frequency.
3. Installing and configuring the LG ThinQ app
To control the washing machine through Wi-Fi application required LG ThinQIt is available for Android (version 6.0 and higher) and iOS (version 12.0 and above). Download it from the official stores:

What should I do if my car won't switch to Wi-Fi mode?
If the button Smart ThinQ does not respond or the indicator does not blink:
1. Check if the control panel is locked (some models have a function Child Lock).
2. Make sure the machine is not in wash or pause mode.
3. Try holding the button longer (up to 10 seconds).
4. If nothing helps, reset the machine to factory settings (instructions in section 6).
5. Typical errors and their elimination
Even if you follow the instructions correctly, problems may arise. Let's look at the most common errors and how to solve them:

|---|---|---|
Unable to connect to temporary network |
The smartphone does not see the network LG_WASHER_XXXX |
Restart your machine and router. Make sure the Wi-Fi mode is disabled on your smartphone. Battery saving. |
Incorrect Wi-Fi password |
Typo or password change on the router | Check the password in your router settings. If you recently changed it, reconnect your machine. |
Weak signal |
The machine is far from the router | Use repeater or move the router. Avoid obstacles (walls, furniture). |
Server error (in the ThinQ app) |
Problems on the LG side or traffic blocking | Check your smartphone's internet connection. Restart the app. |
If the machine connects to Wi-Fi, but the application ThinQ doesn't see it, try:
- 🔄 Update the app to the latest version.
- 📱 Reinstall ThinQ (sometimes resetting the cache helps).
