What it means

This code appears on some LG front-load and top-load washing machines fitted with leak protection, and means the leak sensor in the base detected water, so the washer stops the cycle and may run the drain pump. The cause is usually a leak from an internal hose, a drain filter not closed tightly, the door seal, or heavy suds. Do not use the washer until the water source is found; the same code can mean something else on other brands.

Models covered: LG front-load and top-load washing machines (including Direct Drive models); the code shows on the display.

Symptoms4

  • AE shows and the washer stops; the drain pump may run continuously.
  • Water under or around the washer.
  • Suds coming out of the detergent drawer or around the door.
  • The code may return even after the floor is dried.

Possible causes6

  • Drain pump filter not closed tightly after cleaning.
  • Leak from an internal hose or from the inlet or drain hose connection.
  • Torn or damaged door seal, or clothing caught in it.
  • Heavy suds from an unsuitable detergent overflowing inside the washer.
  • Leak from the drain pump or from the tub itself.
  • Water left in the base after an earlier leak keeping the sensor triggered.

How to diagnose5

  1. Turn off the water tap, unplug the washer and dry the floor around it.
  2. Make sure the drain filter is closed tightly and the hose connections at the back are tight and not cracked.
  3. Look at the door seal for tears or trapped clothing, and make sure you use a suitable detergent in the right amount.
  4. Do not tilt the washer to dry the base before the leak source is found, because the code will come back.
  5. A technician unplugs the washer before opening it, traces the leak in the internal hoses, pump and tub, then dries the base and checks the leak sensor.

How to fix5

  1. Close the drain filter tightly and tighten the hose connections.
  2. Use a suitable detergent in the right amount if suds are the cause.
  3. Replace the leaking internal hose or connection.
  4. Replace the door seal or drain pump depending on the leak source.
  5. Once the source is fixed, the technician dries the base and runs a cycle under watch to confirm no leak and no code.

Frequently asked questions

Should I dry the washer base myself to clear the code?

Not before the water source is found. Drying only clears the code for now; it will return on the next cycle if the leak remains. Turn off the tap, unplug the washer and have a technician find the source.

Do all LG washers have this protection?

No, only models with a leak sensor in the base, so check your model's owner's manual to confirm what the code means on it.
