What triggers AE most of the time?

A small internal leak or oversuds/overflow. Common culprits include a loose hose or clamp, a seeping inlet valve, a worn door gasket/bottom seal, a sump/pump seal drip, or too much detergent/rinse aid foaming into the base.

First safe steps

Turn power off to the dishwasher and close the water supply valve. If possible, slide the unit forward a few inches and place towels at the base. Don’t keep restarting cycles until you’ve dried the base and checked the common sources.

Can I clear AE by drying the base?

Yes — carefully dry the base pan with towels and/or a fan. Some homeowners gently tilt the dishwasher forward slightly so trapped water drains onto towels. Don’t force it. Once the base is completely dry, restore power and try a short cycle. If AE returns, stop and schedule service — that indicates an active leak or ongoing moisture intrusion.

What to check after it dries

These are safe, high-payoff checks you can do without disassembly:

• Hoses & clamps: Inspect inlet and drain hoses for slow drips and wet cabinet floors.
• Air gap / high loop: Confirm proper drain routing to help prevent backflow and odd draining behavior.
• Disposal knockout: If the drain hose ties into a garbage disposal and it was recently installed, confirm the knockout plug was removed.
• Door gasket & bottom wiper: Look for tears, warping, or debris preventing a good seal.
• Detergent & rinse aid: Use dishwasher detergent only (never dish soap). Avoid overfilling rinse aid and reduce detergent if foaming is present.

Could oversuds really trigger AE?

Yes. Excess detergent (or any regular dish soap) can foam and reach the leak sensor. After the base is fully dry, run Rinse with no detergent, then use less detergent going forward and double-check your rinse aid setting.

FAQ: LG Dishwasher AE

Q: What does LG dishwasher AE mean?

A: AE indicates moisture or a leak was detected in the base pan. The dishwasher activates leak protection and stops to prevent water damage.

Q: How do I clear an AE error safely?

A: Turn off power and water, then dry the base pan completely using towels and/or a fan. Once fully dry, restore power and run a short cycle. If AE returns, an active leak is present and service is needed.

Q: What common causes should I check?

A: Loose hoses/clamps, a door gasket or bottom seal seep, sump/pump or inlet valve drips, improper drain routing (missing high loop/air gap), a disposal knockout plug still in place, or oversuds from excess detergent or rinse aid.

Q: When should I call a professional?

A: If AE returns after drying the base and correcting routing/detergent issues, schedule service to locate the leak source and repair it.
