Understanding the LG Dishwasher AE Error Code
It was a typical Tuesday evening, and Sarah was just finishing dinner with her family. Her shiny LG dishwasher a gift from her parents when she moved into her first home hummed quietly in the background, doing what it did best. For Sarah, that gentle noise was a symbol of progress. It meant one less chore on her to-do list and more time for bedtime stories with her kids.
But on this particular evening, the rhythm was interrupted. A beep echoed through the kitchen, sharp and insistent, demanding her attention. Sarah walked over, only to be greeted by two letters glowing on the display AE. A simple fault code, yet it felt like the dishwasher was speaking a language she couldn’t understand.

What Does AE Mean?
If you’ve found yourself in Sarah’s shoes, don’t worry you’re not alone. Fault codes like AE can be intimidating at first glance, but they exist to guide you. On LG dishwashers, fault code AE typically indicates a leak or a problem with the flood protection system.
This error appears when the appliance’s sensors detect water buildup in the base of the machine. Think of it as the dishwasher’s way of saying, “I’m trying to protect your home from water damage. Please check me out!”
Why Does This Error Happen?
To understand fault code AE, it helps to unpack why it occurs in the first place. There are a few common culprits:
- Leaking Hoses
The hoses connecting your dishwasher to your water supply might be damaged, loose, or old enough to develop cracks.
- Clogged Filters or Drainage Issues
If the filters or drainage systems are clogged, water can back up into areas where it shouldn’t be, triggering the AE code.
- Door Seal Problems
A worn or damaged door seal can cause water to escape during the wash cycle, pooling at the base of the machine.
- Overloading the Dishwasher
Believe it or not, stuffing a dishwasher to its brim doesn’t make it more efficient. Overloading can create blockages that lead to water leaks.
Facing AE with Patience and a Plan
Think of the AE code like a friend giving you a heads-up before something gets worse. Sarah, for instance, could have ignored the beeping, hoping it would resolve itself. After all, everyone gets busy, and the thought of troubleshooting an appliance is rarely appealing. But she decided to do what her dad always advised her to do in moments like this start simple.
She unplugged the dishwasher and carefully inspected it. Was there visible water near the machine? Could she see evidence of a leak under the dishwasher? Taking even 10 minutes to assess the situation gave Sarah clarity and saved her from panicking.
How to Troubleshoot an AE Fault Code
If you’re dealing with an AE error code, here are a few practical steps to follow:
Step 1: Turn it Off and Disconnect Power
Safety first. Turn off the dishwasher, unplug it from the outlet, or shut off the circuit breaker to avoid any electrical hazards while troubleshooting.
Step 2: Inspect for Leaks
- Check around and under the dishwasher for puddles of water.
- Inspect the hoses for cracks or loose fittings. Tighten or replace as needed.
Step 3: See if the Float Sensor is Stuck
Dishwashers have a float sensor that detects excess water. If the sensor is jammed or falsely triggered, it could mistakenly display the AE code. Manually inspect if the float is stuck and clean away any debris.
Step 4: Examine the Door Seal
Check the rubber gasket around the dishwasher door. If it’s worn out or damaged, it needs replacing to prevent leaks during cycles.
Step 5: Test the Drainage System
Look for blockages in the filter or drain pump. Remove any food debris or buildup that could be causing a backup.
Step 6: Dry Out Water Inside the Dishwasher Base
If water has accumulated in the base, it may need to be manually dried before the AE code will clear. Use a towel or sponge to soak up the water.
When It’s Time to Call for Help
Sometimes, even the most enthusiastic DIYer like Sarah will hit a roadblock. And that’s okay. If your troubleshooting doesn’t resolve the AE error, it’s a good idea to call in a professional. Issues like internal leaks or component failure might require specialized diagnosis and repair.
Just remember, it’s not the end of the world or your dishwasher. Appliances, like people, sometimes just need a little care and maintenance to keep running at their best.
The Lesson from Fault Code AE
For Sarah, the AE error wasn’t just about fixing her dishwasher. It was a reminder that machines, like life, operate best when we take a little time to address issues before they spiral out of control.
Her dad’s advice start simple stayed with her long after the dishwasher was up and running again. Because sometimes, life’s biggest problems can be solved by breaking them into smaller, more manageable steps.
