LG AE

Aqua Stop Error

High severityExpert Guide

What Your Machine Is Actually Telling You

AE means LG's AquaLock leak detection system triggered. A moisture sensor or float switch in the base pan detected water where it shouldn't be.

Common causes:
1. Door seal leak (25%) — gasket torn or debris under seal.
2. Drain hose connection (15%) — loose clamp.
3. Inlet hose leak (15%) — worn washer or cracked hose.
4. Detergent overflow (10%) — excessive suds.
5. Internal hose (10%) — tub-to-pump hose loose.
6. Tub seal (10%) — bearing seal failed.
7. Condensation/splash (10%) — false alarm.
8. Sensor fault (5%) — corroded sensor.

What You're Probably Seeing Right Now

  • AE on display — machine stopped.
  • Water visible under or behind machine.
  • AE during spin — pressure forces leak.
  • AE appeared suddenly — hose disconnected.

DIY Fix — From Easiest to Hardest

1

Turn Off Water (Immediately)

1. Close BOTH taps behind the washer.
2. Unplug machine.
3. Place towels around base.

Find the Leak (10 minutes)

1. Wipe everything dry.
2. Turn on water slowly.
3. Watch for where water appears.

Check Door Seal (5 minutes)

1. Inspect entire rubber gasket.
2. Feel for tears, cuts, hardened sections.
3. Remove trapped debris.
4. Replace if torn ($30-80).
4

Check Hose Connections (5 minutes)

1. Tighten inlet hoses — replace rubber washers.
2. Check drain hose clamp at pump.
3. Inspect internal hoses — tighten clamps.

Dry Base Pan Sensor (5 minutes)

Once leak is fixed:
1. Tilt machine slightly.
2. Dry the base pan.
3. Sensor resets when dry.
4. Power on and test.
