LG Dishwasher AE Code: Leak Detected Checks

LG dishwasher AE is a high-intent leak search. The correct first move is to control water risk, not to keep restarting wash cycles.

Leak risk

Control water risk first

Leak warnings should be treated as water-risk checks. Stop restart attempts until visible water and the door or hose area are reviewed.

At-a-glance diagnosis

Likely meaning

AE usually indicates that the dishwasher detected a leak or water in an area monitored by leak protection.

First safe check

Stop the cycle, check for visible water around the door and under the sink, and avoid moving the unit unless the manual directs it.

Stop point

Stop if water is on the floor, the pump keeps running, or AE returns after the visible area is dry.

Visual check order

  1. 1

    Cancel the cycle if safe.

  2. 2

    Inspect the door seal area for visible water.

  3. 3

    Check sink and disposal drainage.

  4. 4

    Use qualified service for hidden leak tracing.

What AE usually means

AE usually indicates that the dishwasher detected a leak or water in an area monitored by leak protection.

Codes can vary by exact LG dishwasher model number, production year, and regional design. Use this as first-pass guidance, then confirm the model-specific manual or manufacturer support page before opening panels or replacing parts.

First checks

Stop the cycle, check for visible water around the door and under the sink, and avoid moving the unit unless the manual directs it.

Recent oversudsing, a blocked drain, a leaking hose, or water in the base area can all lead to a leak-related warning.

  • Cancel the cycle if safe.
  • Inspect the door seal area for visible water.
  • Check sink and disposal drainage.
  • Use qualified service for hidden leak tracing.

When to stop

Stop if water is on the floor, the pump keeps running, or AE returns after the visible area is dry.

Keep the full model number, exact AE display text, cycle name, and timing ready before contacting LG support or a qualified technician.

Model numbers affected

Commonly searched model families include built-in dishwashers, front-control dishwashers, top-control dishwashers, and compact dishwashers.

This is not a confirmed model-number list. Match the exact code to the full model number on the appliance tag before ordering parts, opening panels, or booking service.
