What Does The LG Dishwasher AE Error Code Mean?

LG Dishwasher AE Error Code

LG dishwashers provide a helpful error code to alert you of the issue. LG dishwasher error codes can be used for diagnostics and troubleshooting, but they are not always necessary to diagnose the problem. LG Dishwasher AE Error Code is one such LG dishwasher error code that indicates an overflow caused by either machine, not at the level, or detergent issues.

The LG Dishwasher AE Error Code indicates that there is a leak somewhere in the unit. Whether the unit is being installed at an angle or the wrong kind of detergent is being used, this error may indicate any number of problems, including those unrelated to the dishwashing cycle.

What Causes The LG Dishwasher AE Error Code?

The LG dishwasher AE error code is caused by an overflow of the unit when it’s not level or due to too much detergent. The LG Dishwasher Error Code AE can also result from a clogged drain filter, which will need to be fixed. We, Will, check all possible causes of this error below.

Using the Wrong Type of Detergent

If your dishwasher is leaking soap bubbles, it may be because of the type of detergent you’re using. Detergents use a process called sudsing to clean dishes — for example, some soaps are created with fatty acid salts that react to water and form bubbles, which lift off grease from dishes.

When you’re using a dishwasher, make sure wash detergents are optimized for the machine. If you don’t, then it won’t be able to do its job. Specifically, soap that isn’t designed for use in a dishwasher can cause a buildup of suds around the door. 

This buildup can mean that the door doesn’t seal properly. As a result, excess water can leak out through the door’s seal, creating a mess on your floor and causing the LG Dishwasher AE Error Code.

The solution is simple: use the right dishwasher soap.

The Dishwasher is Not level

A dishwasher that leans forward can cause a leak. You might notice water leaking from underneath the door or even in the bottom of the dishwasher. Over time, this can cause a lot of damage, as water can get into electrical components and ruin entire pieces of equipment.

Misaligned dishwashers can cause a host of problems. For instance, the unit may drain slowly; water maybe splashing around inside the unit or hide in corners, and mildew may grow on the floor and walls. That’s why it’s best to know how to correct misalignment so you can fix these and other dishwasher issues.

Install shims underneath your dishwasher until the unit is level. Each time you adjust your dishwasher, measure its height from the dishwasher base to the floor. If required, add or remove a shim to get it in line with the floor.

Clogged Drain Filter

If possible, you should regularly inspect the dishwasher filter. It is responsible for cleaning water from any large food particles or foreign objects that might get into the machine. Over time, the filter may accumulate bits of food and build-up, which will actually prevent it from effectively cleaning the dishes, but even worse, it can also cause leakages.

To clean a dishwasher filter: 

  • Remove it from the machine and hand-wash it in warm, soapy water.
  • Rinse the filter thoroughly under running water. 
  • For food particles that are stuck to the filter, scrub gently with a sponge or an old toothbrush. 
  • Examine the area where you installed filters for food remnants — this is especially important for filters placed near the bottom rack of your dishwasher. 
  • To wipe them clean, use a damp towel.

Defective Float Switch

The float switch is a fail-safe mechanism that helps to prevent too much water from flowing into the dishwasher tub. When the water reaches a certain level, it rises and lowers to detect the water level.

If the water level rises more than what’s expected, the float switch shuts off the inlet valve to prevent water from flowing into the tub.

A malfunctioning overfill float switch could lead to leaks. The overfill float is underneath your dishwasher and has the ability to stop excess water from entering the tub when it reaches a dangerous level.

It is located inside the tub. The mushroom float can do its job properly, but only if the overfill float switch is working properly. If either one of them is failing, you’ll need to replace both for a safer dishwasher.

Broken Hose

The dishwasher drain hose brings water from your dishwasher to the drain pump. In order for this tube to work correctly, it needs to be connected and sealed properly. If water leaks out through the outlet end of the hose, it may be loose or disconnected. If the hose is damaged, it can easily tear, causing leaks (LG Dishwasher AE Error Code) and making fixing the water leak a difficult task.

Secure the drain hose at both ends of the appliance by tightening the sink and dishwasher openings with pliers. Next, place a shallow pan beneath the appliance and turn off the power. The water inside it will drain into the pan. Remove any excess water from the pan before reconnecting the hoses to their ports.

Faulty Inlet Valve

If your dishwasher is leaking from the bottom, it’s likely due to a broken or improperly seated water inlet valve that allows water to flow into the dishwasher tub. If this valve doesn’t open and closes properly, your appliance may overfill. The excess water will usually leak out of the bottom spray arm or around the door.

The dishwasher inlet valve can’t be repaired, so you have two options: order a new one to replace the old, or continue using the dishwasher only as a manual washer. The former is preferable for its safety, but if you are short on cash or don’t want to throw out your old appliance, the latter is also an option.

LG Dishwasher Error Code AE Will Not Turn Off

LG dishwashers are designed to be durable and long-lasting, but on occasion a fault can appear. In case you’re having problems with your LG dishwasher, check these errors and faults.

The self-protection system of the LG dishwasher protects it from damage. If the system detects water flooding or an exceptional amount of water, it will shut off to prevent any further damage. Nonetheless, you can check if a fault has occurred by resetting the device and performing a cycle with fewer dishes; if this doesn’t work, contact your local service for advice on how to repair the machine.

The LG dishwasher has an amazing self-repairing mechanism that is unlike any other design. The water leak protection system, when activated, stops the machine from running its current cycle — resulting in a complete breakdown of the machine’s functionality. Thus, the code AE is displayed on the front screen.

This means that your dishwasher’s protection system has been triggered and it will not function in any mode until it is repaired by a professional engineer on site.

Final Thoughts

The LG dishwasher has an LG AE Error Code. This message is most often the result of a leak from the appliance, which can be caused by either not leveling it or improper detergent levels.

It may also be due to a clogged drain filter; defective float switch, broken hose; faulty inlet valve. It may also be due to an LG dishwasher not being used for a while, or the unit is installed too close to the sink.

The LG Dishwasher AE Error Code is a problem that can be solved by following the troubleshooting steps in this post. If you have any trouble with these steps or your dishwasher doesn’t seem to have an error code, let me know in the comments below, and I’ll try to help.

  1. I have an LG dishwasher Model number LDF5545ST with a continuous Error Code AE.
    It was operating normally until I ran it without the top rack and it’s sprayer installed. I wanted to wash items that wouldn’t fit with the top rack installed.

    In hindsight without that top sprayer it probably introduced too much water.

    There is no water visible leaking from the machine. Also if I pour a pitcher of water into the machine I can hear the water being pumped out and into the garbage disposal, so I assume the hoses are not blocked.

    I have removed the filter from inside the machine and cleaned it. Viewing into the hole it fits into there is no debris visible

    Any ideas for me?

    Thank you.

  2. Would a leak from the lower seal cause this error also?

    One other thing is how to reset the error code once you’ve tried to fix the issue?

    Thanks

  3. I have the AE code happening and of course I shut it off at the fuse box. I then cleaned out the filter which was needed. I did use a different cleaner, they didn’t have my usual. But the code won’t go off. Any other ways to get it to reset?
    Thanks,
    Michele
