How To Fix The LG Dishwasher AE Error Code?


LG dishwasher AE error code means your device is leaking. You should check for water leaks and determine the source of the problem.

You may not see the water flowing from the outside. However, behind the unit is a tray with a built-in float. Water collects in this tray if a leak occurs, causing the float to rise upwards. The sensor informs the control board that the LG dishwasher is leaking. As a result, the error code AE appears. Aquastop – the leakage prevention system – is another name for this unit. In this article, Jacob Dillard, an engineer at Appliance Repair Expert, will talk in detail about this problem and how to solve it.

What Should You Check First If Your LG Dishwasher Shows The Error Code AE?

Water leaks may occur for a variety of reasons. The issue might be one of the following:

Dishwasher door seal is not tight 

It’s the most typical issue that can be indicated by specific LG dishwasher error codes. To fix a leak, open the door and remove the damaged latch or gasket.

Then, purchase a replacement gasket for your LG dishwasher model. Insert the new element into the place where the old one was removed.

Apply the sealant to the dishwasher door frame.

Slowly go around the dishwasher door. If the seal is too long, cut it to the desired length with scissors.

Inspect pipes and hoses

Clogged sewers and drains may cause your dishwasher to leak. Inspect and clean the filters and hoses regularly for remaining food.

The filter located at the bottom of the tank is easy to clean. Remove the fine mesh and rinse the item under water to clean it.

Examine the connections of pipes and the tightness of hoses. Turn the unit upside down and remove the drip tray. You can see the inside of it under the tray.

Check the hose connections to the components for leaks and replace them if necessary. Even a droplet can become a jet when the dishwasher is switched on. In this case, the LG dishwasher may display the error code AE.

Check the water sensor

Inspect the inlet valve. If it shows signs of rust, this is the first sign that the part needs to be replaced.

The water level sensor is typically positioned on the base or pallet next to the Aquastop system (the leak prevention device.)

If water leaks, it means that the valve malfunctions or does not operate correctly. The control board does not receive a water level signal, the pump does not start, and the Aquastop protection activates. Water leaks out of the sump onto the floor if there is a lot of water. To solve the problem, replace the sensor.

AE code indicates an internal water leak that likely requires the replacement of a specific part, such as a gasket, pipe, valve, or sensor. Regular maintenance and inspection can reduce the likelihood of the issue, but professional repair of LG dishwashers may eventually be required.
