What the Rinse Aid Notification Means
The rinse aid notification on an LG ThinQ dishwasher is a maintenance reminder, not a fault code.
It appears when the dishwasher detects that the rinse aid dispenser is low, empty, or needs attention before the next wash cycle.
Rinse aid helps water sheet off dishes, reduces spotting, and improves drying performance, especially on glassware and plastic items.
If the message stays on after refilling, the issue is usually tied to the dispenser setting, the sensor, or the way the dishwasher was reset.
How to Clear the Rinse Aid Notification on LG ThinQ Dishwasher
The most reliable way to clear the rinse aid notification on LG ThinQ dishwasher models is to refill the dispenser fully, close it securely, and run a normal cycle if needed for the system to update.
Some models clear the alert immediately, while others require a short delay or a cycle completion before the indicator disappears.
- Open the dishwasher door and locate the rinse aid dispenser on the inside of the door.
- Turn the dispenser cap to open it.
- Fill the reservoir with rinse aid up to the maximum line.
- Wipe away any spills around the cap and seal.
- Close the dispenser firmly until it clicks or locks.
- Start a wash cycle if the notification does not clear right away.
If the indicator remains visible, check the rinse aid setting in the control panel or LG ThinQ app.
On some LG dishwashers, the notification is linked to the amount of rinse aid selected, so increasing the dosage setting can help the sensor register the refill properly.
Check the Rinse Aid Dispenser Setting
LG dishwashers often let you adjust rinse aid output to match water hardness and drying needs.
If the dispenser is set too low, the machine may continue showing the notification sooner than expected, especially in areas with hard water.
- Set a higher rinse aid level if dishes still appear spotted or wet.
- Use a lower setting if you see streaks, rainbow film, or excess suds.
- Consult the owner’s manual for the exact adjustment method for your model.
The LG ThinQ app may also display appliance status and alerts, depending on your model.
If the app shows the rinse aid message but the control panel does not, refresh the appliance connection and confirm the dishwasher is online.
When the Notification Will Not Clear
If you have refilled the dispenser and the warning still stays on, the problem is usually one of a few common causes.
These issues are typically simple and do not require a service call right away.
Air trapped in the dispenser
Sometimes the dispenser does not register the refill because air pockets prevent the liquid from settling properly.
Tapping the door gently or topping off the reservoir can help the sensor detect the refill.
Residue around the cap
Dried rinse aid can build up around the opening and interfere with the cap seal.
Clean the dispenser edge with a damp cloth, then dry it before closing the cap again.
Sensor delay
Some LG ThinQ models update the rinse aid status only after a cycle or after the dishwasher powers through a short internal check.
In this case, the notification may clear after the next wash rather than immediately.
Very low rinse aid level setting
If the dosage setting is near the minimum, the dishwasher may still behave as though the reservoir is low.
Increase the setting slightly and monitor the alert over the next few loads.
Reset and Power-Cycle Steps That May Help
When the normal refill process does not work, a basic reset can help the dishwasher refresh its status.
This is not a factory reset; it is a simple power-cycle that can clear temporary display issues.
- Turn off the dishwasher using the control panel.
- Unplug the unit or switch off the circuit breaker for about one minute.
- Restore power.
- Check whether the rinse aid notification is still displayed.
If your LG ThinQ dishwasher supports app-based controls, open the app and confirm that the appliance status has synced.
A delayed Wi-Fi update can make the warning appear longer than it should.
How to Prevent the Alert From Returning Too Soon
Frequent rinse aid warnings usually point to heavy usage, a low dispenser setting, or a leak at the cap.
A few small changes can reduce how often the alert comes back.
- Use a quality rinse aid approved for automatic dishwashers.
- Refill before the dispenser reaches empty if you wash daily.
- Match the setting to your water hardness and drying results.
- Keep the dispenser cap clean and tightly closed.
- Check for moisture or residue around the dispenser after each refill.
Homes with hard water often need a higher rinse aid dose because minerals make drying slower and spotting more likely.
In that case, the alert may return faster simply because the machine is using more rinse aid per cycle.
Rinse Aid Notification vs Other Dishwasher Alerts
It helps to distinguish the rinse aid reminder from other LG dishwasher alerts.
The rinse aid message usually does not indicate a mechanical problem, while error codes such as IE, OE, or LE point to water, drainage, or motor-related issues.
- Rinse aid notification: refill reminder for drying performance.
- Water supply or drainage codes: indicate a plumbing or pump issue.
- Door or latch issues: may prevent a cycle from starting properly.
If the dishwasher will not run, or if multiple alerts appear at once, the rinse aid message may not be the main issue.
In that situation, review the other code first.
When to Check the Owner’s Manual or Contact Support
Model differences matter with LG appliances.
Some ThinQ dishwashers clear the notification through the front panel, while others rely on specific menu steps, app settings, or cycle completion to update the indicator.
Check the owner’s manual if you do not see a clear rinse aid level setting or if the display behaves differently from other LG models.
If the notification stays on even after refilling, power-cycling, cleaning the dispenser, and adjusting the setting, contact LG support for model-specific guidance.
Support may recommend a diagnostic check if the dispenser sensor seems unresponsive or if the warning appears even when the reservoir is full.
That is uncommon, but it can happen on units with a faulty sensor or control board.
Quick Checklist for Clearing the Alert
- Refill the rinse aid dispenser to the max line.
- Wipe away residue and close the cap securely.
- Increase the rinse aid setting if needed.
- Run a cycle or wait for the dishwasher to update.
- Power-cycle the dishwasher if the alert persists.
- Check the LG ThinQ app for a synced status update.
Once the system recognizes the refill, the notification should disappear and drying performance should improve over the next few wash cycles.
