Common LG Dishwasher Error Codes and Their Meanings

When an error code appears on your LG dishwasher, identifying the code is the first step towards a solution.

Below are some of the most frequently encountered LG dishwasher error codes and their meanings:

Error Code OE: Drainage Issue 

This code indicates a drainage problem, typically due to a clogged filter or drain hose, preventing the water from draining out properly.

Error Code IE: Water Inlet Problem 

When this code appears, it generally means there’s an issue with the water supply, such as a kinked inlet hose or a closed water valve.

Error Code AE: Leakage Detected 

AE signifies that the dishwasher has detected a leak. This might occur if water is pooling at the bottom of the appliance due to a faulty door seal or hose connection.

Error Code FE: Overflow Detected 

This code is triggered when there’s an overflow, which could happen if the water supply pressure is too high or if there’s an issue with the inlet valve.

1. Resolving the OE Error Code (Drainage Issue)

If your dishwasher isn’t draining, here’s how to address the problem:

To troubleshoot a leak, follow these steps:

1. Turn off the dishwasher: Disconnect the appliance to avoid any electrical hazards.

3. Check hose connections: Ensure all hoses are securely connected and check for cracks or wear.
