LG Dishwasher Fault Code AE: Easy Way to Fix It Fast

Are you frustrated by your LG dishwasher showing the AE fault code? Don’t panic! This guide will help you understand what it means and how to fix it quickly.

The LG dishwasher AE fault code usually means a problem with water leakage. It can be caused by blocked drains, faulty sensors, or water pressure issues. Checking hoses, cleaning filters, and inspecting the float switch can often solve it.

Knowing this will save you money and prevent damage. Always unplug your dishwasher before working on it, and carefully follow each step to fix the issue safely. Small, simple actions often fix the problem without professional help.

Steps to Fix Your LG Dishwasher Fault Code AE

Check for Water Leakage

Water leakage is the most common reason for the AE error. First, look under the dishwasher for visible water. Even small amounts can trigger the code. Use a towel to dry the base and check hoses for cracks or loose connections. Make sure the drain hose is properly attached and not bent. If you find a leak, tighten connections or replace damaged hoses immediately.

Next, check the water inlet valve. Sometimes it leaks slowly, causing the AE error. Inspect the valve for water stains or damp areas. If it looks damaged, replace it. Also, make sure the door seal is clean and intact. Any gap can let water escape. Regularly cleaning the seal with a soft cloth prevents buildup.

Finally, test your dishwasher after fixing leaks. Run a short cycle and watch for the AE code. If it comes back, there may be a sensor issue. Otherwise, you solved the problem. Fixing leaks early avoids serious water damage in your kitchen.

• Check under the dishwasher for water
• Inspect hoses and tighten connections
• Check inlet valve for leaks
• Clean and inspect door seal
• Run a test cycle

Inspect the Float Switch

The float switch senses water levels in the dishwasher. If it’s stuck or dirty, the AE code appears. Open the bottom panel and locate the float switch. Gently move it up and down. If it doesn’t move freely, clean it carefully. Sometimes debris blocks its movement.

After cleaning, test the float switch with a multimeter for continuity. If it fails, replace it. A faulty switch will not detect water correctly, triggering the AE error. Using the correct replacement ensures your dishwasher works safely. Always turn off power before testing electrical parts.

Next, check the float housing for cracks. Water can leak inside, causing errors. Replace any damaged parts promptly. Finally, reassemble the bottom panel and test a wash cycle. The AE code should disappear if the float switch was the issue.

• Locate and move float switch
• Clean any debris blocking movement
• Test with a multimeter
• Inspect float housing for cracks
• Reassemble and run test cycle

Clean and Check Filters

Clogged filters can cause water to overflow, triggering the AE code. Remove the dishwasher filter and rinse it under running water. Make sure no food or debris blocks the mesh. Even small particles can affect water flow. Clean regularly to prevent future problems.

Next, check the spray arms for clogs. Remove them and rinse thoroughly. Use a toothpick or small brush to remove stuck debris. Proper water flow is critical for dishwasher operation. Dirty spray arms can also cause leaks that lead to the AE error.

Finally, inspect the drain pump filter. It often collects dirt and small pieces of glass. Carefully clean it and ensure it spins freely. Replace any damaged filters immediately. Test the dishwasher after cleaning to ensure smooth operation and no AE code.

• Remove and clean dishwasher filter
• Clean spray arms thoroughly
• Inspect drain pump filter
• Remove debris blocking water flow
• Run a test cycle

Examine the Drain Hose

The drain hose can be blocked or bent, causing water to back up. Check the hose for kinks or sharp bends. Straighten it out to allow proper drainage. Inspect the connections at both ends for leaks. Tighten clamps if needed.

Next, remove the hose and flush it with water. Use a long brush to remove stubborn debris inside. Any blockage can cause water to accumulate and trigger the AE code. Inspect the end of the hose for buildup. Cleaning regularly prevents recurring issues.

After cleaning, reattach the hose securely. Run a cycle and monitor the dishwasher. If water drains properly and AE code is gone, the problem is solved. Regular maintenance of hoses prevents expensive repairs later.

• Check hose for kinks or bends
• Tighten connections and clamps
• Flush hose with water
• Remove internal debris
• Test dishwasher

Inspect Water Pressure

Incorrect water pressure may trigger AE errors. Low pressure can prevent proper filling, while high pressure may cause leaks. Check the water supply valve and make sure it is fully open. Measure pressure with a gauge if necessary.

Next, inspect the inlet hose for blockages. Remove it and flush water through to ensure flow is smooth. If the pressure is too low, clean or replace the inlet valve. High pressure may need a regulator to prevent leaks. Always use proper parts for replacement.

After adjusting water pressure, run a test cycle. Watch for AE code. Correct pressure ensures your dishwasher fills and drains correctly. Maintaining it improves cleaning performance and prevents leaks.

• Check water supply valve
• Measure water pressure
• Inspect and flush inlet hose
• Replace or adjust valve if needed
• Test dishwasher

Reset the Dishwasher

Sometimes, resetting the dishwasher clears the AE code. Turn off power for at least 5 minutes. Unplug or switch off the circuit breaker. This allows the control board to reset.

Next, plug the dishwasher back in and start a short cycle. Watch for any error codes. If the AE code returns, further troubleshooting is needed. Resetting often solves minor electronic glitches without repairs. It’s an easy first step before more complex checks.

• Turn off power completely
• Wait at least 5 minutes
• Plug back in and start cycle
• Monitor for AE code
• Repeat reset if necessary

Why AE Code Appears Frequently

The AE error can come from many small issues. Over time, hoses loosen, filters clog, and water sensors fail. Regular inspection prevents this. A small leak or dirty component can trigger the code even if the dishwasher seems fine.

Additionally, using hard water increases deposits, which may affect sensors and float switches. Cleaning with vinegar or descaler monthly helps. It prevents the buildup that can cause AE errors. Proper maintenance keeps the dishwasher running smoothly for years.

Check connections, hoses, and filters after each few months. This reduces the chance of AE code appearing unexpectedly. Sometimes the AE code is a warning for future damage. Taking action quickly avoids expensive repairs or water damage.

• Inspect hoses and filters regularly
• Clean sensors and float switches
• Use water softeners if needed
• Monitor dishwasher after cycles
• Take action early
