How to Clear LG Dishwasher Error Codes

LG dishwashers are known for their efficiency and convenience, but like any other appliance, they can encounter issues that result in error codes. These error codes are your dishwasher’s way of communicating a problem. While they can be frustrating, they are usually straightforward to diagnose and resolve. In this guide, we’ll walk you through the steps to clear LG dishwasher error codes.

Understanding LG Dishwasher Error Codes

Before attempting to clear error codes, it’s essential to understand what the code means. LG dishwasher error codes are typically displayed as a combination of letters and numbers. Common error codes include “IE” (inlet error), “OE” (outlet error), “LE” (leak error), and “FE” (fill error), among others. You can refer to your dishwasher’s user manual or LG’s official website to find the specific meaning of the error code.

Safety Precautions

Before you begin troubleshooting and clearing error codes, ensure your safety:

  1. Power Off: Always disconnect the power supply to the dishwasher by unplugging it or switching off the circuit breaker to prevent electrical accidents.
  2. Wait for It to Cool: If your dishwasher has recently been in use, wait for it to cool down before attempting any repairs.

Steps to Clear LG Dishwasher Error Codes

1. Identify the Error Code

As mentioned earlier, it’s crucial to know what error code you’re dealing with. Refer to your dishwasher’s user manual or look up the specific code online to determine its meaning.

2. Check for Obvious Issues

Sometimes, error codes can be triggered by simple issues like a blocked water supply or a clogged filter. Check the following:

  • Water Supply: Ensure that the water inlet valve is fully open, and there’s no kink in the inlet hose.
  • Filters: Clean the dishwasher’s filters, as a dirty filter can cause drainage problems.

3. Reset the Dishwasher

Resetting the dishwasher can often clear error codes:

  • Press Start/Reset Button: Press and hold the Start/Reset button for about 5 seconds. This should reset the dishwasher.

4. Run a Test Cycle

After resetting the dishwasher, run a test cycle to see if the error code reappears. Follow these steps:

  • Close the dishwasher door securely.
  • Select a cycle and press Start. Allow the dishwasher to complete the cycle.

5. Consult the User Manual

If the error code persists after resetting and running a test cycle, consult your dishwasher’s user manual for specific troubleshooting steps related to the error code. LG often provides detailed guidance for each code in their manuals.

6. Contact LG Customer Support

If none of the above steps resolve the error code, it’s time to contact LG customer support or a qualified technician. Provide them with the specific error code and details about the issue you’ve encountered.

7. Address Specific Error Codes

a. IE (Inlet Error)

  • Check the water inlet valve for any clogs or obstructions.
  • Ensure the water supply to the dishwasher is turned on and not restricted.
  • Examine the inlet hose for kinks or damage.

b. OE (Outlet Error)

  • Verify that the drain hose is not kinked or clogged.
  • Ensure the dishwasher’s drain filter is clean and free of debris.
  • Check for any blockages in the sink’s plumbing that might be affecting drainage.

c. LE (Leak Error)

  • If your dishwasher has a visible leak, turn off the water supply and unplug it immediately.
  • Check the dishwasher’s door seal for damage or wear and replace if necessary.
  • Inspect the tub and hoses for cracks or loose connections.

d. FE (Fill Error)

  • Make sure the water inlet valve is fully open and functioning correctly.
  • Check for kinks or twists in the water inlet hose.
  • Examine the water pressure; low water pressure can trigger this error.

e. HE (Heater Error)

  • If you encounter this error, the dishwasher’s heating element may be faulty. It might require replacement, and it’s advisable to contact a technician for this issue.

8. Perform a Hard Reset

  • In some cases, a hard reset can clear persistent error codes. To do this, unplug the dishwasher from the power source for a few minutes and then plug it back in. This can help reset the dishwasher’s control board.

9. Firmware Update

  • Some LG dishwashers allow for firmware updates through a USB connection. Check if your dishwasher model has this feature and if there are any available updates on LG’s official website. An outdated firmware can sometimes cause error codes.

10. Seek Professional Assistance

  • If you’ve followed all the steps mentioned above and the error code still persists, it’s time to call in a professional technician. They have the expertise and diagnostic tools to identify and fix more complex issues with your dishwasher.
