The IE error on an LG dishwasher can be a frustrating issue to deal with, especially if you’re unsure of how to fix it. This error indicates that the dishwasher is not filling with water properly or at all, which can prevent you from being able to clean your dishes effectively. Fortunately, there are several troubleshooting steps you can take to resolve this problem. In this comprehensive guide, we will cover everything you need to know about the IE error, its causes, and how to fix it.


To fix the IE error on an LG dishwasher, first check if your home’s water pressure is above 20 PSI. Next, inspect the water inlet filter for clogs and clean or replace it if necessary. Also, examine the water supply line for any kinks or bends and ensure the water supply valve is fully open. If the error persists after these steps, seek professional help. Regular maintenance of your dishwasher can help prevent this error in the future.

What is the IE Error?

The IE error on an LG dishwasher is a code that signifies a problem with the water inlet in the dishwasher. This error typically occurs when there are issues such as low water pressure, a clogged water inlet filter, a kinked or bent water line, or a closed or partially closed water supply valve.

Main Causes of the IE Error

Understanding the main causes of the IE error can help you troubleshoot and fix the issue more effectively. Here are the common causes of the IE error:

  1. Low water pressure: The dishwasher may not be receiving adequate water pressure to fill the appliance properly. The water pressure in your home should be above 20 PSI for the dishwasher to operate correctly.
  2. Kinked or bent water line: If the water line connected to the dishwasher has kinks or bends, it can restrict the water flow.
  3. Closed or partially closed water supply valve: If the water supply valve connected to the dishwasher is not fully open, it can limit the water supply.
  4. Clogged inlet screens: The inlet screens on the water supply hose can get clogged over time, restricting water flow.

How to Fix the IE Error

Now that you understand what causes the IE error, let’s look at how you can fix it. Here are some steps to follow:

  1. Check the water pressure: Make sure your household water pressure is above 20 PSI. You can check this with a water pressure gauge that can be purchased at most home improvement stores.
  2. Inspect the water inlet filter: A clogged water inlet filter can cause the IE error. To clean the filter, disconnect the water supply hose from the inlet water valve and check the filter screen for any clogs. If the screen is clogged, clean or replace it.
  3. Examine the water supply line: Check the water line for any kinks or bends and straighten them if necessary. Also, ensure that the water supply valve is fully open.
  4. Clean the dishwasher regularly: Regular maintenance can help prevent buildup and improve the dishwasher’s performance. This includes cleaning the spray arms and filters and using a dishwasher cleaner or deodorizer to remove any odor.

If you’ve tried these steps and the IE error persists, it’s recommended to consult a professional technician for further assistance.

Preventing the IE Error in the Future

To prevent the IE error from recurring in the future, regular maintenance of your dishwasher is essential. This includes checking the water pressure regularly, cleaning the water inlet filter, inspecting the water supply line, and regular cleaning of the dishwasher. By following these steps, you can ensure optimal performance of your dishwasher and prevent the IE error.

When to Seek Professional Help

There are cases when professional help should be sought to fix the IE error on an LG dishwasher. If you have checked the water inlet filter, water line, and water pressure, but the IE error persists, it’s advisable to contact LG customer support or a qualified appliance repair technician. Additionally, if you’re not comfortable performing the troubleshooting steps yourself or lack the necessary tools, seeking professional help is the best course of action.

In conclusion, while the IE error on an LG dishwasher can be a daunting issue to resolve, it’s not impossible to fix. With a little troubleshooting and regular maintenance, you can keep your dishwasher running smoothly. Remember, if the problem persists after attempting these fixes, don’t hesitate to seek professional help.
