Common Causes of the LG Dishwasher AE Error Code
The AE or E1 error code is a critical alert that the float switch has been triggered. This usually happens when water overflows into the bottom tray of the machine. Common culprits include unlevel installation, dirty door seals, or blocked spray nozzles that redirect water incorrectly.
Before attempting any repairs, always disconnect the power supply to ensure your safety. A simple reset rarely works because the physical water must be removed from the sensor area first. Addressing the root cause is the only way to prevent the error from returning.

Recommended Replacement Parts for LG Dishwashers

If your inspection reveals a torn gasket or a cracked spray arm, it is vital to replace them with genuine OEM parts. Using third-party components may lead to improper fitment and recurring AE error codes. High-quality seals ensure a watertight environment during high-pressure wash cycles.
Always verify your specific model number before purchasing replacement parts. A faulty water inlet valve is another common part that fails over time, leading to slow leaks. Keeping these components in top condition will extend the life of your LG dishwasher significantly.
FAQ
Can I clear the AE error by simply unplugging the dishwasher?
Unplugging the unit may temporarily clear the code, but it will return as long as water remains in the drain pan. You must physically dry the base of the unit to deactivate the float switch sensor. Once the area is dry and the leak source is fixed, the code will disappear.
Why does my LG dishwasher leak only during certain cycles?
This often happens due to clogged spray arms or using too much detergent. Clogged nozzles can spray water at odd angles, forcing it past the door seal. Similarly, excessive suds can create pressure that pushes water into the base pan, triggering the AE sensor.
Is the AE error the same as the E1 error?
Yes, on most LG models, AE and E1 both indicate a leak detection or a float switch activation. Both codes require the same troubleshooting steps, focusing on leveling, seals, and drying the bottom tray. They are designed to protect your kitchen from water damage.
