How to Fix the AE Error Code on Your LG Dishwasher: A Comprehensive Guide

The AE error code on your LG dishwasher indicates a leak. This guide provides a step-by-step approach to diagnose and fix the issue, saving you time and potentially expensive repair costs.

Understanding the AE Error Code

The AE error code specifically points to a leak detection issue. The dishwasher’s sensors have detected water where it shouldn’t be, triggering the error and halting the cycle. It’s crucial to address this promptly to prevent water damage to your kitchen.

Step-by-Step Troubleshooting Guide

Here’s a detailed guide to help you resolve the AE error code:

1. Safety First: Disconnect the Power

  • Before you begin, disconnect the dishwasher from its power source. This is a critical safety precaution to prevent electrical shock.
  • Turn off the circuit breaker dedicated to the dishwasher.

2. Check for Obvious Leaks

  • Inspect around the dishwasher: Look for any visible water pooling on the floor around the unit.
  • Check the door seal: Examine the rubber gasket around the dishwasher door for damage, cracks, or debris. A faulty seal is a common cause of leaks.
  • Inspect hoses: Look at the inlet and drain hoses for kinks, cracks, or loose connections. Tighten connections if necessary.

3. Inspect the Interior of the Dishwasher

  • Check the spray arms: Make sure the spray arms are not clogged or damaged. Clogs can cause water to spray in the wrong direction, potentially leading to leaks.
  • Inspect the float switch: The float switch is usually located at the bottom of the dishwasher tub. Ensure it moves freely and isn’t stuck in the up position. If it’s stuck, it might indicate excessive water.
  • Check the wash pump: Look for any signs of leaks around the wash pump, which is responsible for circulating water during the wash cycle.
  • Check the drain pump: Similar to the wash pump, inspect the drain pump for leaks. It’s responsible for draining water from the dishwasher.

4. Clean the Drain and Filter

  • A clogged drain can cause water to back up and leak. Remove and clean the dishwasher’s filter located at the bottom of the tub.
  • Check the drain hose for clogs: Disconnect the drain hose from the garbage disposal or sink drain and inspect it for obstructions. Flush it with water to remove any debris.

5. Check the Water Inlet Valve

  • The water inlet valve controls the flow of water into the dishwasher. Inspect it for leaks or damage.
  • If the valve is faulty, it may need to be replaced.

6. Inspect the Float Switch Assembly

  • The float switch assembly, including the float and the switch itself, signals when the water level is too high. Damage can cause the error code.
  • Visually inspect the float and switch. Check continuity with a multimeter to verify functionality.

7. Reset the Dishwasher

  • After addressing potential leak sources, reset the dishwasher to clear the error code.
  • Hard Reset: Turn off the power at the circuit breaker for 5-10 minutes, then turn it back on.
  • Control Panel Reset: Some models have a reset button or a combination of buttons that can be pressed to reset the system. Consult your user manual.

8. Run a Test Cycle

  • After resetting, run a short test cycle to see if the AE error code reappears.
  • Monitor the dishwasher closely for any signs of leaks during the cycle.

When to Call a Professional

If you’ve tried all the troubleshooting steps and the AE error code persists, it’s time to call a qualified appliance repair technician. The problem could be a more complex issue, such as a faulty pump, a cracked tub, or an electrical problem.

  • Don’t attempt repairs you’re uncomfortable with. Working with electrical components and water can be dangerous.
  • A professional technician has the tools and expertise to diagnose and repair the problem safely and effectively.

Preventing Future Leaks

  • Regularly clean the filter: A clean filter prevents clogs and ensures proper drainage.
  • Inspect hoses and connections: Check hoses and connections periodically for signs of wear and tear.
  • Avoid overloading the dishwasher: Overloading can strain the components and increase the risk of leaks.
  • Use the correct detergent: Using the wrong type or amount of detergent can cause excessive suds, which can lead to leaks.

By following these steps, you can effectively troubleshoot and potentially fix the AE error code on your LG dishwasher, saving time and money. Remember safety is paramount, and when in doubt, call a professional.
