Are you frustrated with your LG dishwasher showing the IE error? Don’t worry; you’re not alone. The IE error, which stands for Inlet Error, is a common issue that many LG dishwasher owners encounter. It indicates a problem with the dishwasher’s water inlet system, preventing it from filling with water properly. But fear not! In this article, we’ll guide you through the troubleshooting process step by step, so you can get your dishwasher back to its efficient cleaning glory.

1. Check the Water Supply

The first thing you should do when encountering the IE error is to check the water supply. Make sure the water supply valve connected to the dishwasher is fully open. Sometimes, the valve might get accidentally closed, disrupting the water flow. If the valve is already open, you can try turning it off and then back on again to see if it resolves the issue.

2. Inspect the Inlet Hose

The next step is to inspect the dishwasher’s inlet hose for any kinks or clogs. The inlet hose is the tube that connects the water supply to the dishwasher. Sometimes, it can get twisted or blocked, leading to the IE error. Straighten out any kinks in the hose and remove any debris or blockages if you find them.

3. Check the Water Filter

LG dishwashers are equipped with a water filter to prevent debris from entering the dishwasher’s system. However, if the filter gets clogged, it can disrupt the water flow and trigger the IE error. Locate the filter inside the dishwasher and clean it thoroughly. Refer to your dishwasher’s manual for specific instructions on how to remove and clean the filter.

4. Verify the Float Assembly

The dishwasher’s float assembly is a small device located at the bottom of the dishwasher tub. Its purpose is to monitor the water level inside the dishwasher. If the float gets stuck or is obstructed, it can erroneously signal an overflow condition, resulting in the IE error. Gently lift the float and ensure it moves freely without any obstructions.

5. Examine the Water Inlet Valve

The water inlet valve controls the water flow into the dishwasher. A malfunctioning valve can cause the IE error to appear. To check the valve, disconnect the dishwasher from the power and water supply. Then, access the valve and inspect it for any signs of damage or debris. If you suspect the valve is faulty, it might need to be replaced.

6. Test the Water Pressure

Inadequate water pressure can also trigger the IE error. To test the water pressure, turn off the dishwasher and disconnect the inlet hose from the water supply valve. Place a container under the open end of the hose and turn on the water supply valve. The water should flow out with decent pressure. If the pressure is low, there might be an issue with your home’s water supply that needs to be addressed.

7. Reset the Dishwasher

Sometimes, a simple reset can resolve minor glitches causing the IE error. To reset your LG dishwasher, turn it off and unplug it from the power source for a few minutes. Then, plug it back in, turn it on, and check if the error persists. If the IE error was caused by a temporary hiccup, the reset should clear it.

8. Seek Professional Help

If you’ve tried all the above steps and the IE error still persists, it’s time to seek professional help. LG dishwashers come with a warranty, and if your dishwasher is still covered, contact LG customer support or an authorized service center to schedule a repair. They have the expertise and tools to diagnose and fix complex issues with your dishwasher.


Dealing with the IE error on your LG dishwasher can be frustrating, but with the troubleshooting steps mentioned above, you can diagnose and resolve the issue. From checking the water supply and inspecting the inlet hose to examining the water inlet valve and resetting the dishwasher, these steps cover the most common causes of the IE error. Remember to refer to your dishwasher’s manual for specific instructions and safety guidelines. If all else fails, don’t hesitate to contact professional technicians to ensure your dishwasher gets the proper care it deserves.
