How to Update Software on LG ThinQ Dishwasher
If you want your smart appliance to stay connected, responsive, and compatible with the LG ThinQ app, knowing how to update software on LG ThinQ dishwasher models matters.
The process is usually simple, but the exact steps depend on the dishwasher’s model, Wi-Fi connection, and whether a firmware update is available.
LG uses software updates to improve connectivity, fix bugs, and sometimes add features that help the dishwasher work better with the ThinQ ecosystem.
Here is how the update process works, what to check before you start, and what to do if the update does not appear.
What software updates do on an LG ThinQ dishwasher
LG ThinQ dishwashers use embedded firmware to manage functions such as cycle control, alerts, Wi-Fi communication, and app integration.
A software update can improve how the dishwasher communicates with the LG ThinQ app, resolve intermittent connection problems, and refine system stability.
In many cases, updates are delivered over-the-air through the appliance’s Wi-Fi connection.
That means you do not usually need a USB drive or service visit.
However, not every model receives updates at the same time, and some updates may be pushed automatically by LG rather than manually initiated.
Before you start the update process
Before attempting an update, make sure the dishwasher is ready for a stable software transfer.
This reduces the chance of failed downloads or incomplete installations.
- Confirm that the dishwasher is connected to a strong 2.4 GHz Wi-Fi network.
- Make sure the LG ThinQ app is installed on your smartphone and signed in.
- Check that your router is online and the signal is stable near the dishwasher.
- Keep the dishwasher powered on during the update process.
- Do not start a wash cycle while checking for updates.
If the dishwasher recently lost power or Wi-Fi, reconnect it first.
A weak signal is one of the most common reasons an LG appliance fails to detect a firmware update.
How to update software on LG ThinQ dishwasher through the app
The most common method is through the LG ThinQ mobile app.
The menu labels may vary slightly by app version and dishwasher model, but the general process is similar.
- Open the LG ThinQ app on your phone.
- Select your dishwasher from the device list.
- Tap the settings or device information section.
- Look for a software update, firmware update, or device update option.
- If an update is available, follow the on-screen prompts to begin installation.
During the update, avoid closing the app, disconnecting Wi-Fi, or turning off the dishwasher.
Some updates complete in a few minutes, while others may take longer depending on the file size and network speed.
What if no update option appears?
If you do not see an update prompt, that does not necessarily mean something is wrong.
The dishwasher may already be running the latest firmware, or LG may not have released an update for your specific model yet.
Try refreshing the appliance screen in the app, reconnecting the dishwasher to Wi-Fi, or closing and reopening the ThinQ app.
If the issue continues, check the model documentation or LG support pages for confirmation that your appliance supports remote firmware updates.
How to reconnect a dishwasher if the update fails
When a software update does not start or stops midway, the underlying problem is often connectivity rather than the firmware itself.
Reconnecting the dishwasher to Wi-Fi usually resolves the issue.
- Open the LG ThinQ app and remove the dishwasher from the device list if needed.
- Restart the dishwasher and your router.
- Reconnect the appliance to Wi-Fi using the app’s device setup flow.
- Confirm that the dishwasher shows as online before checking for updates again.
LG ThinQ appliances generally work best on a 2.4 GHz network.
If your router combines 2.4 GHz and 5 GHz under one name, temporary band steering can sometimes interfere with initial setup.
If you continue to have trouble, try simplifying the network environment during setup.
Signs your LG ThinQ dishwasher may need an update
Not every appliance displays a clear update prompt.
Still, a few symptoms can suggest that your dishwasher would benefit from updated firmware.
- The dishwasher frequently drops offline in the LG ThinQ app.
- Cycle status or notifications fail to sync correctly.
- Remote monitoring works intermittently.
- App commands lag or do not register reliably.
- LG support recommends updating for a known issue.
These signs do not always mean the firmware is outdated, but they are worth checking if your smart features are not performing as expected.
How to verify the update was installed
After an update finishes, confirm that the dishwasher is still connected and responding normally in the LG ThinQ app.
If the app shows the device online, the update likely completed successfully.
You can also review the device information screen in the app for a version number or update history, if your app version displays that detail.
If the dishwasher behaves normally after the update and reconnects without errors, that is another good sign the installation succeeded.
Troubleshooting common update problems
Some update problems are easy to fix once you identify the cause.
The most common issues involve Wi-Fi, app permissions, or temporary server delays.
The dishwasher is offline in the app
Check the router, verify the dishwasher is powered on, and make sure the appliance is within range of the network.
Restarting both the router and dishwasher can clear temporary connection errors.
The app says an update is available, but it will not start
Close and reopen the LG ThinQ app, then check for account sign-in issues.
Also confirm that the phone has a stable internet connection, because the app may need to communicate with LG servers before launching the update.
The update stops halfway
This is often caused by weak Wi-Fi or a brief network interruption.
Keep the dishwasher powered on, improve the signal if possible, and retry the update once the network is stable.
The dishwasher is updated but still acting oddly
If smart features remain unreliable after the update, remove and re-add the appliance in the LG ThinQ app.
If the problem continues, contact LG support with the model number, current firmware version, and a description of the issue.
Best practices for keeping LG ThinQ dishwasher software current
Routine maintenance helps smart appliances stay dependable.
While LG may push updates automatically in some cases, it is still smart to check the app periodically, especially after app changes or network changes.
- Keep the dishwasher connected to a stable home Wi-Fi network.
- Update the LG ThinQ app on your phone regularly.
- Use the same LG account for device management.
- Leave the appliance powered on so scheduled updates can complete.
- Review LG support notices for model-specific firmware guidance.
For homeowners using multiple LG smart appliances, consistent network settings can prevent device confusion and reduce reconnection issues.
A reliable router, strong signal, and updated app environment make firmware updates much smoother.
When to contact LG support
If the dishwasher refuses to connect, the update option never appears, or repeated update attempts fail, LG support may need to help.
Have your model number, serial number, and a summary of the steps you already tried ready before contacting them.
Support can confirm whether your LG ThinQ dishwasher is eligible for a firmware update, whether the update is being rolled out in stages, and whether there is a known issue affecting your specific model.
