LG Dishwasher ae error code
The dishwasher detected water in its base pan, which means a leak or overflow. It will often run the drain pump continuously as protection, even with the door open.
Also shown as: ae, AE
Last updated: October 6, 2026
What causes the ae error?
- Leaking door seal or gasket
- Loose hose clamp inside the unit
- Cracked sump or drain hose
- Too much detergent foam overflowing into the base
- Inlet valve stuck open letting water in
How to fix LG ae — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Turn off water and power
Shut the water supply valve to the dishwasher and unplug it or switch off the breaker. Do not keep running cycles while it is leaking. - Look for visible water
Check under and around the dishwasher for puddles. Mop up any water you can reach so the base float can drop back down. - Inspect the door seal
Open the door and check the gasket for food debris, cracks, or folds. Clean it with a damp cloth and make sure it sits evenly all around. - Power reset after everything is dry
Once the area is dry and the leak source is addressed, restore power and run a short cycle while watching for the code.
When to call a technician
- Water keeps appearing under the unit
- The pump runs constantly with no water inside
- The inlet valve lets water in even when off
- You suspect an internal hose or sump leak
Frequently asked questions
I see no water, but AE is still showing. Why?
The sensor sits in a hidden base pan under the unit. Water can be trapped there even when the floor looks dry.
Why does the pump keep running with AE?
It is a flood-protection response. The dishwasher pumps continuously to keep water from rising.
Can too much detergent cause AE?
Yes. Excess foam can overflow internal parts and drip into the base, tripping the leak sensor.
