LG dishwashers are known for their efficiency and smart features, but like any appliance, they can occasionally display error codes that interrupt your cleaning cycles. One of the more common issues is the LE error code. Understanding what this code means, why it occurs, and how to resolve it can help you get your dishwasher back to optimal performance quickly.

What the LE Error Code Means

The LE error on an LG dishwasher indicates a leak detected in the appliance. This safety feature is designed to prevent water from flooding your kitchen. When the dishwasher senses water where it shouldn’t be—usually in the base pan under the appliance—it triggers the LE code and stops the cycle.

Common signs of an LE error include:

• Dishwasher stops mid-cycle and shows “LE” on the display
• Water or moisture detected under the dishwasher
• Hoses or connections that appear wet or leaking
• Unusual sounds from the appliance as the leak sensor is triggered

Why the LE Error Occurs

There are several reasons the LE code might appear:

• Water leaks from hoses or connections due to age, loosened clamps, or cracks.
• Door gasket failure allowing water to escape from the front of the dishwasher.
• Cracks or damage in the tub or base pan where water accumulates.
• Faulty leak detection sensor giving a false reading.
• Overfilling due to improper detergent use or a malfunctioning water inlet valve.

How to Diagnose and Fix the LE Error

You can troubleshoot an LE error with a few careful steps:

Step-by-Step DIY Guide:

1. Turn Off the Dishwasher: Disconnect power or turn off the circuit breaker to ensure safety.
2. Inspect for Water Leaks: Pull out the dishwasher and check under and around it for water pooling. Examine hoses, clamps, and the base pan for moisture or damage.
3. Check the Door Seal: Look at the rubber gasket around the door. If it’s cracked, torn, or worn out, water may be escaping during cycles.
4. Examine Tub and Pan: Inspect the dishwasher tub and base pan for cracks or damage that could allow water to reach the leak sensor.
5. Test the Leak Sensor: If no visible leak is found, the sensor itself may be faulty. Inspect the wiring and connections; a multimeter can be used to check continuity according to the service manual.
6. Fix or Replace Parts: Replace damaged hoses, seals, or sensors as needed. Make sure all clamps are tight and the appliance is properly reinstalled.

Most often, replacing a worn door gasket or fixing a loose hose resolves the LE error. If the tub itself is damaged, professional service may be required.

Preventive Measures

Preventing leaks can reduce the likelihood of the LE code appearing in the future:

• Regularly inspect hoses, clamps, and connections for wear or looseness.
• Clean and maintain the door gasket to prevent cracks and tears.
• Avoid overfilling the detergent dispenser or using excessive detergent.
• Ensure the dishwasher is level to prevent uneven water distribution.
• Check the base pan periodically for any signs of moisture.

Quick Troubleshooting Checklist

• Disconnect power and inspect for water under the dishwasher
• Check hoses, clamps, and water inlet connections
• Examine the door gasket for cracks or damage
• Inspect the tub and base pan for leaks or cracks
• Test or replace the leak sensor if no visible leak is found

Addressing an LE error promptly helps prevent water damage and ensures your LG dishwasher continues to clean efficiently. With careful inspection and routine maintenance, many of these issues can be avoided entirely, keeping your appliance running smoothly for years.
