Unraveling the Mystery of LG Dishwasher Error Code AE
Your LG dishwasher is a trusted part of your daily routine, delivering sparkling clean dishes without the hassle of scrubbing and drying by hand. But then, an ominous AE code flashes on the control panel. Panic sets in you’re faced with a disruption that feels like a domestic disaster. Take a deep breath. This isn’t as daunting as it seems.
Below, we will guide you through what the AE code means, why it may appear, and what actionable steps you can take to get your dishwasher running again.

What Does the AE Code Mean?
An LG dishwasher displaying the AE error code indicates leak detection. This is the machine’s built-in float sensor that triggers this effect. In easier terms, it’s the sensor trying to convey to you there is water somewhere it shouldn’t be, like the bottom of the dishwasher.
It is not just a puddle of water in your kitchen; this is how the dishwasher protects itself, your appliance, and your home from further damage. You may consider it an early warning system in relation to catching any problem before it has grown.
Common Causes of the AE Code
Don’t worry just yet. There are a few reasons why the AE code would appear, and they don’t always point to an expensive repair. Here’s why you might be seeing that pesky code:
Overloading or Improper Loading
Sometimes we overload the dishwashers in a hurry, just to avoid doing it all over again. However, overloaded or wrong positioning may lead to water spraying out of the compartments and dripping where they should not.
Leaky or Damaged Door Gasket
The gasket is the rubber seal around the dishwasher door designed to keep water in. Over time, this can wear out and become cracked, allowing room for leaks.
Loose or Cracked Hoses
Inside your dishwasher, water flows through a set of hoses. Over time, these can work themselves loose or crack, leading to the water escaping and triggering the AE error.
Clogged Drainage System
Food debris and particles block the draining system to back up water in the bottom of your dishwasher.
Dishwasher not level
Even a minimal lean can displace water wrongly inside the unit. A not at level dishwasher might accidentally trick the float sensor to show there is a leak.
Overuse of Detergent
Too much or the wrong type of detergent can cause excess suds that may overflow and trick the sensor into displaying an AE error.
How to Fix the AE Code
The good news is that many AE code issues can be fixed without calling in a technician. Here’s what to do when this warning pops up:
Step 1: Inspect and Dry the Interior
The AE code is most often triggered by water accumulation at the bottom, caused by the float sensor. Check for water by unplugging your dishwasher and removing its bottom panel. Dry the area completely with a towel or sponge and wait a few hours before restarting.
Step 2: Check for Leaks Around the Door
Check the gasket around the door of the dishwasher. It should not have cracks, tears, or other forms of wear. This may be the solution-replacing a gasket-to cease the leak and prevent further leaks.
Step 3: Look for Loose or Broken Hoses
Look for visible cracks in the water inlet and drain hoses of the dishwasher. Also, review loosened connections. If yes, then tighten or replace them.
Step 4: Clean the Drain and Filter
Clean out your dishwasher’s filter and drainage areas of any food particles and debris. Pour some warm water with baking soda into the drainage system to clear blockages.
Step 5: Level Your Dishwasher
Using a leveling tool, see whether your appliance is seated properly on the floor. Where necessary, adjust the legs so that the dishwasher is completely level.
Step 6: Check Your Detergent
Use only recommended detergents in your LG dishwasher and take proper measurements as specified in the user manual. Remember, a little is better than a lot. Using too much detergent causes heavier foaming that may trigger the AE code.
Step 7: Run a Test Cycle
Once you’ve addressed the possible causes, plug the dishwasher back in and run an empty test cycle. If the AE code has cleared, congratulations—you’re back to doing dishes like a pro. If not, it might be time to consult a technician.
When to Call in the Professionals
If you have followed all the above steps and the AE error still persists, or if you see obvious damage, such as a cracked internal component, then it is time to seek a professional technician. Sometimes, attempting to fix major leaks or broken sensors may cause more harm than good. In that case, deeper mechanical issues require expertise that may only be provided by LG’s support team or an authorized service provider.
Tips to Avoid AE Error in the Future
A few easy tips for maintenance to keep your dishwasher at its best and not develop any other AE error in the future include:
Load Smartly
Do not overload your dishwasher; place items as instructed inside the manual.
Clean the Filter Regularly
Take out the filter once a month for cleaning to avoid blockages.
Check Seals and Hoses for Damage or Wear
It is a good practice to annually inspect gaskets and hoses for any damage or wear.
Use the Appropriate Detergent
Follow the manufacturer’s instructions regarding types and amounts of detergent.
Regular maintenance will go a long way in keeping your dishwasher running smoothly and error-free.
All Clean and Problem-Free
The next time the AE code appears, don’t panic it’s your dishwasher’s way of protecting itself and your kitchen from potential damage. Use the steps above to troubleshoot the issue, and you’ll likely have it fixed before your next meal.
