LG Dishwasher Error Code AE

The AE code on an LG dishwasher means the unit has detected water leaking into the base or drip tray at the bottom of the machine. When this happens, the dishwasher sounds an alert for 10 seconds and runs the drain pump intermittently to remove the accumulated water. The unit will also power itself back on automatically if switched off, and will continue this behavior until the leak condition is resolved. Shutting off the water supply to the dishwasher is the recommended first step.

No, you should not continue running the dishwasher while the AE code is active. The code indicates water is actively leaking into an area of the unit where it can damage flooring, cabinetry, and potentially create an electrical hazard. Turn off the water supply valve to the dishwasher immediately and leave it off until the leak source has been identified and repaired.

Repair costs depend entirely on the source of the leak. A simple fix like reseating a hose clamp may cost very little if done without a service call, while replacing a door gasket typically runs in the range of $20 to $80 for the part. Pump seal or inlet valve replacements, combined with a technician's labor, can bring total repair costs to anywhere from $100 to $300 or more depending on the specific component and your location.

Some causes of the AE error, such as a loose hose clamp or incorrect detergent use, can be addressed without professional help. However, because the code involves active water leakage, identifying the exact source requires pulling the dishwasher out and inspecting internal components including the pump seals, hose connections, and inlet valve. If you are not comfortable working with plumbing connections or disassembling the lower cabinet of the unit, contacting LG customer support or a licensed appliance technician is the safer option.

Resetting the dishwasher will not permanently clear the AE code if the underlying leak has not been fixed. The leak detection sensor in the base tray will continue to trigger the error as long as moisture is present. Additionally, the dishwasher is designed to power itself back on automatically after being turned off while the AE condition is active, so a simple reset or power cycle will not bypass this safety behavior.
