Experiencing an “AE” error code on your LG dishwasher can be frustrating, interrupting your daily chores and leaving you wondering about the cause and, more importantly, how to fix it. This persistent error typically signifies a problem with the dishwasher’s water intake or drainage system, often related to a blockage or a malfunction in the inlet valve or pump. Fortunately, in many cases, a reset procedure can resolve this issue. This comprehensive guide will walk you through understanding the AE error, exploring the reset process, and providing detailed steps for troubleshooting and preventing future occurrences.
Understanding the LG Dishwasher AE Error Code
The AE error code on LG dishwashers is a diagnostic indicator pointing to a water-related issue. While the exact interpretation can vary slightly between LG dishwasher models, it most commonly relates to:
- Water Inlet Problems: The dishwasher might not be receiving enough water, or it’s not filling at all. This could be due to a kinked water supply hose, a closed water valve, a clogged inlet filter, or a faulty inlet valve.
- Drainage Issues: Conversely, the AE error can also indicate a problem with water draining out of the dishwasher. This might stem from a blocked drain hose, a clogged drain filter, or a malfunctioning drain pump.
- Pressure Sensor Malfunctions: In some instances, the error could be triggered by a faulty water level or pressure sensor that’s incorrectly detecting the water level.
The key takeaway is that the AE error signals an anomaly in how water is entering or leaving your LG dishwasher. Recognizing this will help you approach the troubleshooting process more effectively.
The LG Dishwasher Reset: Your First Line of Defense
Before diving into more complex diagnostic steps, attempting a reset is often the simplest and most effective way to clear the AE error code. A reset can effectively reboot the dishwasher’s control panel, clearing temporary glitches or minor software errors that might be triggering the code.
How to Perform a Power Cycle Reset
The most common and recommended method for resetting your LG dishwasher is through a power cycle. This involves disconnecting the appliance from its power source for a specific period.
Follow these steps carefully:
- Locate the Power Source: Identify where your LG dishwasher is plugged into the electrical outlet. This might be directly behind the unit or accessible through a nearby cabinet.
- Unplug the Dishwasher: Carefully pull the power cord from the outlet. If your dishwasher is hardwired, you will need to turn off the circuit breaker that powers the appliance. It’s crucial to ensure the power is completely disconnected for the reset to be effective.
- Wait Patiently: This is a critical step. Leave the dishwasher unplugged for at least 5 to 10 minutes. This extended period allows the internal capacitors to discharge and the control board to fully reset. Rushing this step might render the reset ineffective.
- Plug Back In or Restore Power: Once the waiting period is over, plug the dishwasher back into the outlet or turn the circuit breaker back on.
- Test the Dishwasher: Turn on your LG dishwasher and try to run a short cycle. Observe if the AE error code has disappeared. If it has, congratulations! You’ve successfully reset your dishwasher. If the error persists, you’ll need to move on to more in-depth troubleshooting.
Why Does a Power Cycle Reset Work?
Modern appliances like LG dishwashers are sophisticated electronic devices. Like computers, they can sometimes encounter minor software hiccups or temporary glitches that lead to error codes. A power cycle effectively acts like restarting your computer: it clears the temporary memory and allows the system to start fresh. This process can often resolve phantom errors that don’t necessarily indicate a serious hardware failure.
Troubleshooting the AE Error Beyond a Simple Reset
If the power cycle reset doesn’t clear the AE error code, it’s time to investigate potential underlying causes. This often involves checking accessible components for blockages or simple issues.
Checking the Water Supply
A primary culprit for the AE error code is insufficient or interrupted water supply.
- Water Valve: Ensure the water supply valve, usually located under the sink, is fully open. Sometimes, these valves can be accidentally partially closed.
- Water Inlet Hose: Inspect the water inlet hose that connects the water supply to the dishwasher. Look for any kinks, twists, or damage that could restrict water flow. Straighten any kinks you find.
- Inlet Filter: Many LG dishwashers have a small filter screen at the point where the water inlet hose connects to the dishwasher itself. This filter can become clogged with sediment over time. To check and clean it:
- Turn off the water supply to the dishwasher.
- Disconnect the water inlet hose from the dishwasher.
- Carefully remove the filter screen. You might need a pair of pliers for this.
- Rinse the filter under running water to remove any debris.
- Reinstall the filter and reconnect the water inlet hose.
- Turn the water supply back on and check for leaks.
Investigating Drainage Issues
If the water supply seems fine, the AE error might be related to drainage.
- Drain Filter: Almost all dishwashers have a drain filter at the bottom of the tub to catch food debris. A clogged drain filter is a very common cause of drainage problems.
- Open the dishwasher door and locate the filter at the bottom of the tub. It’s usually a cylindrical or mesh component that can be unscrewed.
- Remove the filter and rinse it thoroughly under running water. You might need to use a brush to dislodge stubborn debris.
- Inspect the area where the filter sits for any large food particles that might have bypassed the filter.
- Reinstall the filter securely.
- Drain Hose: The drain hose that carries water from the dishwasher to your sink’s drain or garbage disposal can become kinked or clogged.
- Check for any visible kinks in the drain hose.
- If accessible, disconnect the drain hose from the dishwasher (after placing a bucket to catch residual water) and blow through it or try to flush it with water to check for blockages.
- Ensure the end of the drain hose connected to your sink or disposal isn’t submerged too deeply in standing water, which can prevent proper drainage.
Checking the Air Gap (if applicable)
Some dishwasher installations include an air gap, a small cylindrical fixture usually found on the countertop near the faucet. The air gap prevents dirty sink water from backing up into the dishwasher. If this air gap becomes clogged, it can impede drainage.
- Remove the cap from the air gap.
- Check for any debris or blockages inside the air gap.
- Clean out any obstructions and replace the cap.
The Importance of a Thorough Manual
Every LG dishwasher model is slightly different. The most accurate information regarding error codes and troubleshooting steps for your specific appliance can be found in its user manual. If you’ve misplaced your physical copy, you can usually find a digital version on the LG website by searching for your model number. Always refer to your manual as a primary resource.
When to Call a Professional
While many AE error codes can be resolved with basic troubleshooting and a reset, there are instances where a professional technician is necessary.
- Persistent AE Error: If you’ve performed all the troubleshooting steps mentioned above, and the AE error code continues to appear, it suggests a more complex internal issue.
- Suspected Component Failure: If you suspect a problem with internal components such as the inlet valve, drain pump, or water level sensor, attempting repairs yourself could void your warranty or lead to further damage. These components require specialized knowledge and tools to diagnose and replace.
- Water Leaks: If you notice any significant water leaks around your dishwasher during operation, it’s a clear sign that a professional should be called.
- Unfamiliarity or Discomfort: If you’re not comfortable performing any of the troubleshooting steps, or if you’re unsure about what you’re doing, it’s always best to err on the side of caution and contact a qualified appliance repair technician.
Preventative Measures to Avoid Future AE Errors
Implementing a few preventative habits can significantly reduce the likelihood of encountering the AE error code again.
- Regular Cleaning: Make it a habit to clean your dishwasher’s filter regularly. A quick rinse every few weeks, or more often if you notice heavy debris, can prevent clogs from forming.
- Proper Loading: Avoid overcrowding the dishwasher and ensure that larger food particles are scraped from plates before loading. This prevents excessive debris from reaching the filter and potentially clogging the drain.
- Rinse Aid Usage: Using rinse aid can help water sheet off dishes, promoting better drying and potentially reducing the strain on the drainage system.
- Water Softener: If you live in an area with very hard water, consider installing a water softener. Hard water can lead to mineral buildup that can affect various components of your dishwasher over time.
- Periodic Inspection: Occasionally, take a moment to visually inspect the water inlet hose for kinks and ensure the water valve is fully open.

Can I reset my LG dishwasher after seeing the AE error code?
Yes, a reset is often the first and simplest troubleshooting step for an LG dishwasher displaying the AE error code. This error typically indicates a water leak or a problem with the water sensor. A reset can help clear temporary glitches or misinterpretations by the dishwasher’s control panel that might be causing the error to display erroneously.
To perform a reset, locate the power button on your LG dishwasher. Press and hold the power button for approximately 5-10 seconds until the unit powers off completely. Wait for about 30 seconds, and then press the power button again to turn the dishwasher back on. Observe if the AE error code reappears after the reset.
What does the AE error code on my LG dishwasher signify?
The AE error code on an LG dishwasher generally points to a water leak detected within the appliance. This could be due to a faulty seal, a cracked hose, or a problem with the water inlet valve. The dishwasher’s internal sensor has identified water where it shouldn’t be, triggering the error to prevent further damage or water wastage.
In some instances, the AE error might also be triggered by a malfunctioning water level sensor itself, even if there isn’t a significant leak. This means the sensor might be falsely reporting the presence of water. Regardless of the exact cause, the AE error signifies a water-related issue that requires attention.
How do I perform a hard reset on my LG dishwasher?
A hard reset is essentially the same as the initial reset described, involving disconnecting the dishwasher from its power source. This is a more thorough way to clear any persistent error codes or memory issues within the control board. Unplug the dishwasher directly from the wall outlet to ensure it’s completely de-energized.
After unplugging, wait for at least one to two minutes. This duration allows any residual power in the control board to dissipate, ensuring a complete system refresh. Then, plug the dishwasher back into the outlet. Turn it on using the power button and check if the AE error has been cleared.
What are common causes of the AE error code on an LG dishwasher besides a leak?
While a water leak is the most frequent cause, the AE error can sometimes be triggered by a faulty water inlet valve. This valve is responsible for allowing water into the dishwasher, and if it’s stuck open or malfunctioning, it could lead to an overfill situation or the sensor detecting unwanted water. Additionally, a problem with the drain pump or a clog in the drain line could sometimes contribute to error codes related to water management.
Another less common but possible cause is an issue with the main control board. If the board itself is experiencing a malfunction, it might misinterpret sensor readings or fail to properly control water levels, leading to the AE error. In such cases, the error may not be directly related to a physical leak but rather an internal electronic problem.
If a reset doesn’t fix the AE error, what should I check next?
If a power reset doesn’t resolve the AE error, the next step is to manually inspect the dishwasher for visible signs of a water leak. Carefully examine the base of the dishwasher, the area around the door seals, and any accessible hoses for dampness, puddles, or dripping water. Pay close attention to connections and any components that come into contact with water.
While inspecting, also check the dishwasher’s drain system. Ensure the drain hose isn’t kinked, blocked, or submerged in water in the sink drain. A clogged drain can prevent water from properly exiting the dishwasher, potentially leading to it pooling and triggering the AE error.
When should I consider calling a professional technician for the AE error?
You should consider calling a professional technician if you’ve performed a power reset and thoroughly inspected for visible leaks and drain issues without finding a clear cause or resolution. If you’ve confirmed there’s no obvious leak or blockage but the AE error persists, it suggests a more complex internal problem that may require specialized tools and expertise.
Furthermore, if you’re uncomfortable performing any of the troubleshooting steps, such as disassembling parts of the dishwasher to inspect internal components, or if you suspect a component like the water inlet valve or control board is faulty, it’s best to seek professional help. Attempting repairs beyond your comfort level could lead to further damage or safety hazards.
Can the AE error be a sign of a serious problem that could damage my LG dishwasher?
Yes, the AE error code can indicate a serious problem that, if left unaddressed, could potentially lead to damage to your LG dishwasher and surrounding property. A persistent water leak, even a small one, can damage the flooring, cabinetry, and even the electrical components of the dishwasher itself. This can lead to costly repairs and a shortened appliance lifespan.
The error is designed to alert you to a potential issue to prevent further escalation. Ignoring the AE error and continuing to run the dishwasher can exacerbate any existing leak, potentially causing more significant water damage and making the necessary repairs more extensive and expensive. Prompt attention to this error is crucial.
