If your LG ThinQ dishwasher remote start is not working, the cause is usually a setup, connectivity, or safety setting problem rather than a major failure.
This guide walks through the most common reasons the feature stops responding and how to restore app control quickly.
How LG ThinQ remote start is supposed to work
LG ThinQ remote start is not the same as pressing Start on the dishwasher itself.
On most LG dishwashers, the appliance must first be placed into Remote Start mode at the control panel, then the ThinQ app can send the command from your phone.
For the feature to work reliably, several conditions usually have to be true at the same time:
- The dishwasher must be connected to Wi-Fi.
- The LG ThinQ app must be signed in to the same LG account linked to the appliance.
- Remote Start must be enabled on the dishwasher.
- The door must be closed and latched.
- Control Lock or Child Lock cannot block input.
Common reasons LG ThinQ dishwasher remote start is not working
Most cases come down to one of a few specific issues.
Checking them in order saves time and prevents unnecessary resets.
Remote Start is not enabled at the dishwasher
Many LG dishwashers require you to press and hold the Remote Start button or select the remote option on the control panel before the app can start a cycle.
If the dishwasher is not waiting for a remote command, the app may appear connected but still fail to start the cycle.
The dishwasher is offline
If the appliance loses Wi-Fi, ThinQ cannot send commands.
Weak signal strength, router changes, power interruptions, or band incompatibility can break the connection.
Some LG appliances work best on a 2.4 GHz network rather than 5 GHz.
The door is open or not fully latched
Dishwashers include safety interlocks that prevent remote operation when the door is open.
Even if it looks closed, a misaligned rack, detergent pod, or dirty latch can stop the cycle from starting.
Control Lock is enabled
Control Lock, sometimes called Child Lock, disables keypad input and can prevent remote commands from being accepted.
This setting is easy to overlook because the appliance may still power on normally.
The app or firmware is outdated
Older versions of the LG ThinQ app may not communicate cleanly with newer appliance firmware.
Likewise, the dishwasher may need a software update to improve connectivity or fix remote-command issues.
Account pairing is broken
If the dishwasher was moved, repaired, factory reset, or connected to a new phone, the pairing between the appliance and your LG account may be incomplete.
In that case, the app may show the device but fail when sending a start command.
Step-by-step fixes to try first
Use these troubleshooting steps in order.
They resolve most cases of LG ThinQ dishwasher remote start not working without requiring service.
1. Confirm the dishwasher is in Remote Start mode
At the control panel, activate the remote-start option according to your model’s instructions.
Some models require a long press, while others require you to select a cycle first and then enable remote operation.
2. Close the door firmly
Open the dishwasher, remove anything blocking the door, and shut it firmly until the latch clicks.
If a lower rack is protruding, push it in fully and try again.
3. Check for Control Lock
Look for a lock icon or indicator light on the display.
If the control panel is locked, hold the proper key combination for your model to unlock it before retrying ThinQ remote start.
4. Verify Wi-Fi connection in the ThinQ app
Open the app and confirm the dishwasher shows as online.
If the device appears offline, restart your router, move the appliance closer to the access point if possible, and reconnect the dishwasher to the network.
5. Restart the dishwasher and your phone
Power cycling both devices can clear temporary communication errors.
Unplug the dishwasher or switch off the circuit briefly, restart the smartphone, then reconnect and try again.
6. Update the LG ThinQ app
Install the latest app version from the Apple App Store or Google Play Store.
App updates often include bug fixes for appliance control and cloud communication.
7. Reconnect the appliance to Wi-Fi
If the connection seems unstable, remove the dishwasher from the app and set it up again.
During setup, make sure the correct home network is selected and the password is entered accurately.
Wi-Fi and router issues that can block remote start
ThinQ connectivity problems often come from the home network rather than the dishwasher itself.
Smart appliances are especially sensitive to router settings that phones and laptops tolerate without issue.
- 2.4 GHz versus 5 GHz: Many smart appliances prefer 2.4 GHz for better range and wall penetration.
- Band steering: Routers that automatically switch devices between bands can confuse appliance pairing.
- Guest networks: Guest Wi-Fi often blocks local device discovery and cloud registration.
- Firewall or security settings: Aggressive router security can interfere with IoT communication.
- Weak signal: Dishwashers are often installed in kitchens where metal cabinets and appliances can reduce signal strength.
If the dishwasher is far from the router, consider a mesh Wi-Fi node or access point closer to the kitchen.
A stable signal matters more than raw speed for appliance control.
Model-specific settings that may affect LG ThinQ dishwasher remote start
LG dishwasher features vary by model, so the exact button sequence may differ.
Some models require a cycle to be selected locally before the app can trigger Start, while others allow remote initiation only after the appliance enters standby mode.
Check the following in your user manual or LG support page:
- Whether Remote Start must be turned on after every cycle selection
- Whether the cycle must be paused or idle before remote use
- Whether certain wash options disable remote operation
- How long the appliance remains in remote-ready mode before timing out
Knowing these model-specific limits can prevent repeated failed attempts that look like a network problem but are really a usage restriction.
When the ThinQ app shows the dishwasher, but Start still fails
This usually means the cloud connection is working, but the appliance is refusing the command.
Focus on state changes: door status, lock status, and whether the machine is actually waiting for a remote command.
Also check whether another cycle is already running or whether the dishwasher is paused mid-cycle.
If the app sends a command but nothing happens, sign out of the ThinQ app, sign back in, and test again.
If needed, remove the dishwasher from your LG account and add it back from scratch.
When to reset the dishwasher
A reset is worth trying if remote start worked before and suddenly stopped after a power outage, Wi-Fi change, or app update.
A full reset can clear temporary logic errors and restore the appliance’s network handshake.
Before resetting, save any custom settings and confirm you know the Wi-Fi password.
After the reset, reconnect the dishwasher to ThinQ and re-enable remote operation at the panel.
When to contact LG support
If LG ThinQ dishwasher remote start is not working after verifying Wi-Fi, lock status, door closure, app version, and pairing, the issue may involve a faulty control board, latch sensor, or wireless module.
Contact LG support or a certified appliance technician if you notice any of these signs:
- The dishwasher never enters Remote Start mode.
- The control panel shows error codes.
- The door latch feels loose or inconsistent.
- The appliance disconnects from Wi-Fi repeatedly.
- Physical buttons also respond unreliably.
For service efficiency, note the model number, serial number, app version, router type, and the exact steps that fail.
That information helps support teams narrow down the problem faster.
