What Is LG Washer Error Code AE?

The LG washer error code AE stands for Automatic Error (Leak Detection).
It appears when the washer detects water leakage or excess moisture inside the machine’s base.

LG washers are equipped with a leak sensor at the bottom. When water touches this sensor, the washer immediately stops and shows the AE code to prevent flooding and internal damage.

This error is common in LG front-load washers.

How the AE Error Protects Your Washer

Unlike mechanical failures, the AE code is a safety shutdown.
The washer:

  • Stops mid-cycle

  • Activates the drain pump

  • Prevents further water intake

This protects your home and the washer’s electronics.

Common Causes of LG Washer AE Error

1. Internal Water Leak

Leaks may come from:

  • Drain hose

  • Inlet hose

  • Tub-to-pump hose

  • Door gasket (rubber seal)

2. Excessive Suds

Using too much detergent creates foam that overflows into the base and triggers the leak sensor.

3. Loose Hose Connections

Improperly tightened hoses can drip water slowly, enough to activate the AE code.

4. Cracked or Damaged Components

A cracked pump housing or worn seals can cause internal leaks.

5. Condensation or Spillage

In humid conditions or after moving the washer, moisture can collect at the bottom and trip the sensor.

How to Fix LG Washer Error Code AE

Follow these steps carefully.

Step 1: Turn Off and Unplug the Washer

  • Power off immediately

  • Unplug from the wall

  • This prevents electrical risk

Step 2: Let the Washer Dry

  • Leave the washer unplugged for 24 to 48 hours

  • Tilt it slightly forward if possible

  • Allow the internal base to dry completely

Many AE errors clear once moisture dries out.

Step 3: Check for Visible Leaks

Inspect:

  • Water inlet hoses

  • Drain hose

  • Floor under the washer

  • Door gasket for tears or debris

Tighten or replace faulty parts.

Step 4: Reduce Detergent Usage

  • Use HE detergent only

  • Reduce quantity by half if suds are visible

Excess suds are a very common AE trigger.

Step 5: Restart and Test

  • Plug the washer back in

  • Run a short rinse cycle

  • Monitor for leaks

If AE does not return, the issue is resolved.

What If AE Error Keeps Coming Back?

If the AE code reappears quickly, it usually means:

  • Active internal leak

  • Faulty drain pump or hose

  • Damaged door seal

  • Defective leak sensor

Professional inspection is recommended at this stage.

Can You Use the Washer With AE Error?

No.
Running the washer with an AE error can cause serious water damage and electrical problems.

Always fix the cause before regular use.

When to Call a Technician

Call for service if:

  • Water pools under the washer

  • AE error appears every cycle

  • You hear pump running continuously

  • You cannot locate the leak

For genuine parts and trained service, contact LG authorized support.

How to Prevent LG Washer AE Error

  • Use proper detergent amount

  • Inspect hoses every few months

  • Clean door gasket regularly

  • Avoid overloading

  • Ensure washer is properly leveled

The LG washer error code AE is a leak detection warning, not a random fault. In many cases, drying the washer and fixing minor leaks solves the problem. Persistent AE errors should never be ignored, as they protect your washer and home from serious damage.
