LG Dishwasher Error Code AE

AE usually signals a leak path, overflow, or water-detection event. This page should help users separate a temporary false trigger from a real leak condition.

What AE usually means

AE is commonly associated with leak detection or water where the dishwasher does not expect it. The machine may stop or protect itself by refusing to continue the cycle.

Leak-path alertBase or float triggerDo not keep retrying blindly

What to check first

  • Look for visible leaks around the base, door area, and surrounding floor.
  • Think about recent detergent use because oversudsing can create a false leak-style condition.
  • Check leveling and installation in case water is shifting where it should not.
  • Inspect filters and the lower wash area before repeated restart attempts.

When to stop DIY

Stop if AE returns immediately after reset.

If water keeps appearing under the unit or the alert returns as soon as another cycle starts, move to service-level inspection.
