How to Reset LG Dishwasher AE Code: Troubleshooting Made Easy

In today’s fast-paced world, dishwashers have become indispensable appliances in our kitchens. They save us time and effort, allowing us to enjoy our meals without worrying about the daunting task of dishwashing. LG dishwashers are known for their efficiency and reliability, but like all machines, they can encounter issues from time to time. One common problem that LG dishwasher owners may face is the AE code error. In this article, we’ll guide you through the process of resetting your LG dishwasher when you encounter the AE code, ensuring that your dishwasher is back in perfect working order.

Understanding the AE Code

Before we delve into the reset process, it’s essential to understand what the AE code signifies. AE, in the context of an LG dishwasher, stands for “Auto Error.” It’s a built-in feature designed to alert you when the dishwasher encounters an issue that needs attention. This error code could indicate various problems, such as water supply issues, drainage problems, or even a malfunction in the dishwasher’s components.

Troubleshooting Steps

1. Turn Off and Unplug

The first step in resolving the AE code error is to turn off the dishwasher and unplug it from the power source. This ensures your safety while you work on troubleshooting the issue.

2. Check the Water Supply

One common reason for the AE code is a lack of water supply. Ensure that the water inlet valve is open and that there are no kinks or blockages in the water supply hose.

3. Examine the Drainage System

A clogged drainage system can trigger the AE code. Inspect the dishwasher’s drain hose and filter for any obstructions. Remove any debris or buildup that may be causing the blockage.

4. Inspect for Leaks

Water leaks can also lead to the AE code. Carefully inspect the dishwasher for any visible leaks. If you find any, address them promptly to prevent further issues.

5. Reset the Dishwasher

Now, let’s get to the heart of the matter—resetting the dishwasher. This process may vary slightly depending on your LG dishwasher model. Refer to your user manual for model-specific instructions.

a. Control Panel Reset

For many LG dishwasher models, you can reset the control panel by pressing and holding the Start button for about five seconds. This should clear the error code and allow you to restart the dishwasher.

b. Power Cycle Reset

Alternatively, you can perform a power cycle reset by unplugging the dishwasher for a few minutes and then plugging it back in. This often resolves minor glitches and resets the dishwasher’s system.

6. Run a Test Cycle

After resetting the dishwasher, it’s a good idea to run a test cycle to ensure that the AE code is gone. Load the dishwasher with a few dishes, select a short cycle, and see if it runs without any issues.


Your LG dishwasher’s AE code error may seem daunting at first, but with the troubleshooting steps outlined in this article, you can quickly resolve the issue and have your dishwasher back to its efficient self. Remember to consult your user manual for model-specific instructions and always prioritize safety when working with appliances.
