Is your kitchen suddenly interrupted by an annoying alarm? Getting AE error code LG dishwasher readings can be incredibly frustrating, especially when you are just trying to clean up after a meal. This specific error code, which often flashes on the display panel, is not just a random glitch—it is an official alert from your appliance that it has detected an issue with the water system. In most LG dishwasher models, the AE (or sometimes referred to as the E1) error code signifies a leak or water accumulation in the base pan of the unit.
While seeing an error code might make you panic, it is important to remember that appliance manufacturers design these systems to prevent water damage to your kitchen floors.
The "Aqua Stop" function triggers the AE error to stop the cycle before any flooding occurs.
Understanding why you are getting this code is the first step toward resolving it.
Whether you are dealing with a faulty hose, a worn-out seal, or a loose valve, there are several troubleshooting steps you can take before calling in a professional technician.
Understanding the AE Error Code
The AE error is essentially a safety mechanism.
Located at the bottom of your LG dishwasher is a float switch or a moisture sensor within the base pan.
When water leaks from the internal components—such as the pump, the inlet valve, or a hose connection—it drips down into this bottom pan.
Once the sensor detects liquid, it immediately shuts down the dishwasher and displays the AE code to alert you.
This prevents the dishwasher from continuing to pull water, effectively protecting your cabinetry and flooring.
Common Causes of the AE Error
Before you start taking your dishwasher apart, it helps to identify the usual suspects.
Most often, the culprit is a minor leak rather than a catastrophic failure.
Common causes include:
- Loose or Damaged Hose Connections: Over time, vibrations from the dishwasher can loosen hose clamps, leading to slow drips.
- Faulty Inlet Valve: If the valve that controls water flow into the dishwasher isn't closing properly, it can leak.
- Worn Door Gaskets: If steam or water escapes from the front door during a cycle, it can pool and trigger the sensor.
- Clogged Drain Line: A backup in the drain hose can force water back into the unit, causing an overflow.
Step-by-Step Troubleshooting Guide
If you are getting AE error code LG dishwasher issues, follow these steps to diagnose and potentially fix the problem.
Always remember to prioritize safety by unplugging the dishwasher or turning off the circuit breaker before performing any repairs.
1. The Initial Reset
Sometimes, the sensor may be triggered by a temporary glitch or a very small amount of condensation.
Before doing heavy repairs, try resetting the control board.
Unplug the dishwasher from the power source or flip the circuit breaker off.
Leave it powered down for at least 15 to 20 minutes.
This allows the internal capacitor to discharge and the software to reset.
Plug it back in and start a rinse cycle to see if the error returns.
2. Inspect the Base Pan
If the error returns, you likely have actual water in the base pan.
To check this, you will need to remove the kick plate (the panel at the bottom front of the dishwasher).
You might need a screwdriver for this.
Once removed, use a flashlight to inspect the bottom area.
If you see water pooling, use a sponge or a shop vacuum to dry it out completely.
Once the area is dry, the sensor should reset automatically.
3. Check for Leaks
With the kick plate off, run a test cycle.
Keep a close watch on the hoses, pumps, and valves.
If you see a steady drip or a stream of water, you have found the source.
Tighten any loose hose clamps you find.
If a hose is cracked or a seal is perished, those parts will need to be replaced.
When to Call a Professional Technician
While DIY fixes work for simple hose adjustments or clogs, some issues require expert intervention.
If you have dried out the base pan, tightened all connections, and are still getting the AE error code, the problem may lie deep within the pump assembly or the electronic control board.
Additionally, if the leak appears to be coming from inside the motor housing, it is safer to call a certified technician.
Attempting to repair electrical components without proper training can void your warranty or, worse, result in injury.
Preventive Maintenance Tips
Preventing future AE errors is often easier than fixing them.
Regularly inspect your hoses for signs of wear and tear, such as cracking or brittleness.
Clean your dishwasher filter monthly to prevent drainage issues, which can lead to backflow and leaks.
Lastly, ensure that you are using the correct amount of detergent; using too much soap can cause excessive suds, which may overflow and trigger moisture sensors incorrectly.
By staying proactive, you can keep your LG dishwasher running smoothly for years to come.

Yes, many AE errors are caused by loose hoses or minor leaks that can be fixed by removing the kick plate and drying the base pan.
However, if the issue is with the internal pump or electrical components, a professional is required.
How do I reset my LG dishwasher after fixing the leak?
After ensuring the base pan is dry and all leaks are resolved, you can reset the dishwasher by unplugging it or turning off the circuit breaker for 15-20 minutes, then turning the power back on.
What does the AE error code actually mean?
