LG ThinQ Washer Login Timeout with Samsung SmartThings... | digitalhomefaults.org

Technical Background:

The LG ThinQ washer uses Wi-Fi (2.4 GHz band) for network connectivity and communicates with the cloud via LG's servers. Integration with Samsung SmartThings requires mutual authentication and data exchange through a cloud-to-cloud API. A login timeout suggests a failure during this authentication phase. Samsung SmartThings uses hub-based Zigbee or Z-Wave for some devices but usually relies on the device's native Wi-Fi when integrating with appliances like LG washers. Failure can occur at the account link, authentication, or actual device communication stages. Power cycling the washer and the home's Wi-Fi router is often an initial step to resolve temporary network glitches.

Symptoms:

Washer cannot be added to Samsung SmartThings. The SmartThings app displays a 'Login timeout' error during the device pairing process. The LG ThinQ app may work independently, indicating a problem specific to the SmartThings integration. The washer's Wi-Fi LED may flash intermittently during the connection attempt.

Possible Causes:

Cloud service outage on LG's or Samsung's side.
Incompatible firmware version on the LG ThinQ washer.
Incorrect login credentials entered within the SmartThings app.
Wi-Fi signal interference or weak signal strength (RSSI below -70 dBm) near the washer, especially if using a Bell Giga Hub or Rogers Ignite router.
Firewall settings on the home router blocking communication between the washer and SmartThings cloud servers.
Two-factor authentication (2FA) enabled on the LG account interfering with the SmartThings login flow.

Solution:

1

Verify the Wi-Fi signal strength near the washer using a Wi-Fi analyzer app on a smartphone. Ensure the RSSI is above -70 dBm. Relocate the router or add a Wi-Fi extender if needed.
2

Update the LG ThinQ washer's firmware through the LG ThinQ app. Check for any pending updates in the app's settings menu.
3

Remove the LG account from the SmartThings app and re-add it. Ensure the correct login credentials are used, and temporarily disable 2FA on the LG account to rule it out as a cause.
4

Power cycle the LG ThinQ washer by unplugging it for 5 minutes and then plugging it back in. This resets the network connection.
5

Check the Samsung SmartThings status page for any reported outages or service disruptions.
6

Ensure the home router's firewall is not blocking outbound connections on ports 80, 443, and 8883, which are commonly used for IoT device communication.
7

If using a Bell Giga Hub or Rogers Ignite router, access the router's settings page and ensure that device isolation is disabled. Some routers have a setting that prevents IoT devices from communicating with each other.

Safety Warning:

Never attempt to disassemble or repair the LG ThinQ washer yourself. High voltage AC circuits are present inside. Always disconnect the power supply before performing any maintenance. Ensure that all data transmitted between the LG ThinQ washer and Samsung SmartThings is encrypted to prevent unauthorized access. Do not share login credentials with untrusted parties. Physical tampering with the device's network module can compromise the security of your entire smart home network.

Prevention:

- Periodically check for firmware updates for both the LG ThinQ washer and the Samsung SmartThings hub (if applicable). - Monitor the Wi-Fi signal strength near the washer and ensure it remains stable. - Review and update the LG account password regularly. - Avoid using special characters in the Wi-Fi password, as they can sometimes cause compatibility issues. - Consider assigning a static IP address to the washer on the home network to prevent IP address conflicts.

Expert Tip:

Try using a different Samsung account for the SmartThings integration to isolate potential account-specific issues. Some users have reported success by creating a new Samsung account specifically for smart home integrations.

Frequently Asked Questions

•What are the default ports used by LG ThinQ devices for cloud communication?

LG ThinQ devices commonly use ports 80 (HTTP), 443 (HTTPS), and 8883 (MQTT) for communication with LG cloud services.

•How can I check the firmware version of my LG ThinQ Washer?

Open the LG ThinQ app, select your washer, navigate to settings, and look for the 'Software Update' or 'Firmware Version' option.

•What is the typical Wi-Fi range for an LG ThinQ Washer in a Canadian home environment?

The typical Wi-Fi range is around 15-20 meters, but this can be significantly reduced by walls, appliances, and other sources of interference, especially in older Canadian homes with thick walls.
