Owning a dishwasher has become a modern-day convenience that saves time and effort in our daily lives. LG dishwashers, known for their reliability and performance, are a popular choice for many households. However, like any other appliance, they may encounter issues over time. One common problem that LG dishwasher users might come across is the DE error code. If you see this error on your dishwasher’s display, don’t fret! In this comprehensive guide, we will walk you through the troubleshooting steps to clear the DE error and get your dishwasher back to its efficient self.

Understanding the DE Error:

The DE error code on your LG dishwasher stands for “Drain Error.” It indicates that there is a problem with draining water from the appliance during a wash cycle. There are several reasons why this error might occur, ranging from a clogged drain hose to a faulty drain pump. But before we jump into the solutions, let’s first understand some common factors that can lead to this issue.

  1. Blocked Drain Hose: Over time, debris, food particles, or foreign objects may accumulate and block the dishwasher’s drain hose. This obstruction can prevent water from properly draining, triggering the DE error.
  2. Clogged Filter: The dishwasher’s filter is designed to catch food particles and prevent them from clogging the drain. However, if the filter gets too dirty or clogged, it can hinder the draining process and trigger the error.
  3. Faulty Drain Pump: The drain pump is responsible for removing water from the dishwasher’s tub. A malfunctioning or worn-out drain pump can result in inadequate drainage, leading to the DE error.
  4. Installation Issues: Improper installation, such as an incorrectly installed drain hose or an improperly positioned dishwasher, can cause drainage problems and trigger the error code.

Troubleshooting Steps:

Now that we have a good understanding of the potential causes behind the DE error, let’s get to work and troubleshoot the issue. Follow these step-by-step instructions to clear the DE error in your LG dishwasher:

Step 1: Check the Drain Hose

  1. Start by turning off the dishwasher and disconnecting it from the power source for safety.
  2. Locate the drain hose at the back of the dishwasher. It is usually a flexible, ribbed tube connected to the dishwasher and the sink or garbage disposal.
  3. Carefully inspect the drain hose for any kinks, bends, or obstructions. Straighten out any kinks and remove any visible debris or foreign objects.
  4. If the drain hose appears damaged or severely clogged, consider replacing it with a new one. You can find compatible drain hoses at appliance stores or online retailers.

Step 2: Clean the Filter

  1. Locate the dishwasher’s filter at the bottom of the tub. It is typically found near the back and can be accessed by removing the lower rack.
  2. Take out the filter and rinse it under running water to remove any food particles or debris. Use a soft brush or sponge if necessary to clean stubborn dirt.
  3. Inspect the filter for any signs of damage. If the filter is damaged, replace it with a new one from LG or an authorized distributor.

Step 3: Check the Drain Pump

  1. The drain pump is usually located at the bottom of the dishwasher, near the filter. Before proceeding, make sure the dishwasher is completely disconnected from the power source.
  2. Remove any water that may have accumulated at the bottom of the dishwasher using a sponge or absorbent cloth.
  3. Once the area is dry, inspect the drain pump for any blockages or foreign objects. Clear any obstructions that you find.
  4. Try manually turning the drain pump impeller to check for any resistance or signs of damage. If the impeller does not spin freely, the drain pump may need replacement.

Step 4: Check for Installation Issues

  1. Ensure that the dishwasher is correctly installed, with the drain hose properly connected to the sink or garbage disposal.
  2. Make sure there are no kinks or bends in the drain hose that could obstruct water flow.
  3. Verify that the dishwasher is level and stable. If it’s not properly leveled, water may not drain correctly, leading to the DE error.


Clearing the DE error in your LG dishwasher is a relatively simple task that you can often accomplish on your own. By following the troubleshooting steps outlined in this guide, you can identify and resolve common issues that cause the DE error code. However, if you have gone through all the steps and the error persists, it might be time to contact LG’s customer support or a professional technician for further assistance.

Remember, regular maintenance and proper usage can help prevent many dishwasher issues, including the DE error. Keep the filter clean, avoid overloading the dishwasher, and ensure the drain hose is free from blockages to enjoy hassle-free dishwashing for years to come.

FAQs (Frequently Asked Questions):

Q1: Can I reset the dishwasher to clear the DE error code? A: Yes, you can try resetting the dishwasher to clear the DE error. Simply turn off the power to the dishwasher for about 30 seconds and then turn it back on. In some cases, this can reset the error code and resolve the issue.

Q2: Why is my dishwasher making strange noises when the DE error appears? A: The strange noises you hear may be the result of the dishwasher’s drain pump struggling to remove water due to the error. If the pump is unable to drain water properly, it may make unusual sounds.

Q3: Can I use a generic drain hose instead of an LG-specific one? A: While using a generic drain hose might be possible, it’s recommended to use an LG-specific one or an authorized replacement to ensure compatibility and proper fit.

Q4: What should I do if the DE error persists even after troubleshooting? A: If the DE error persists after following the troubleshooting steps, it’s best to contact LG’s customer support or a certified technician for a thorough diagnosis and repair.

Q5: Is it safe to attempt dishwasher repairs myself? A: While some troubleshooting steps are safe for users to perform, more complex repairs involving electrical or mechanical components should be left to trained technicians to avoid any safety risks.

Q6: How often should I clean the dishwasher’s filter? A: It’s a good practice to clean the dishwasher’s filter at least once a month to prevent debris buildup and ensure efficient draining.

Q7: Can hard water contribute to the DE error in my LG dishwasher? A: Yes, hard water can lead to mineral deposits and buildup in the dishwasher’s components, including the drain pump, which may contribute to the DE error. Consider using a water softener if you have hard water.

Q8: Is the DE error covered under LG’s warranty? A: The DE error caused by manufacturing defects or faulty parts may be covered under LG’s warranty. Contact LG customer support or refer to your warranty documentation for more information.
