Quick answer

On an LG washer, AE means it has detected a water leak. Check the inlet hose for loose connections or cuts, unplug the washer for 60 seconds and start again. If there is water on the floor or the code returns, call service.

Safety first

Stop and check this first

  • Water on the floor and a plugged-in washer are an electrical hazard: unplug it without standing in the water and close the tap before looking for the leak.

Safe checks you can perform

  • Water on or under the floor
  • Inlet hose and its connections
  • Unplug for 60 seconds and restart

Leave these tasks to a qualified professional

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Locating the internal leak

    What they doThe technician opens the washer, checks the base and leak detector and traces the water to the internal connections and components.

    They must show youthe exact leak point and the part or joint involved.

    In writingthe source of the leak, the part replaced with its number and the reason.

  2. Leak-free test after the repair

    What they doAfter the repair, they run a full wash and check the base stays dry and AE does not appear.

    They must show youthe full cycle with a dry base.

    In writingthe test and its result.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Water on or under the floor

    No special tools

    Who:
    you, no tools.
    How:
    look around and under the washer. If there is water, switch off and unplug it without standing in the puddle and close the inlet tap.
    Result that matters:
    whether the leak is visible.
    If there is water:
    do not use it; dry the area and find where it comes from.
    If it is dry:
    move on to checking the hose.
    Evidence to keep:
    photo of the floor and where the water appears.

  2. Inlet hose and its connections

    No special tools

    Who:
    you, with the tap closed.
    How:
    check both threads of the inlet hose and its length for loose connections or cuts, as LG says.
    Result that matters:
    whether the hose is leaking.
    If it is loose or cut:
    tighten or replace it with a suitable hose and try again.
    If it is fine:
    the leak is not coming from there.
    Evidence to keep:
    photo of the connections and any damage.

  3. Unplug for 60 seconds and restart

    No special tools

    Who:
    you, with the floor dry.
    How:
    unplug the washer for 60 seconds, plug it back in and restart the programme, as LG says, staying close to watch.
    Result that matters:
    whether AE returns.
    If it does not return and there is no water:
    it was the hose or a one-off.
    If it returns:
    an internal leak is likely; stop using it and call service.
    Evidence to keep:
    note of the restart and whether water or the code appeared.

What it means

LG's front-load washer list defines AE as water leakage detected and says to check the inlet hose for loose connections or cuts, unplug for 60 seconds and restart. The board uses a leak detector in the base and stops the machine when it trips. The leak may be outside, at the hose or its threads, or inside, in a component only a technician can see. The code does not say where: finding visible water or not, and whether it returns after checking the hose, is what guides it.

Warnings and stop conditions

  • Higheditorial warning

Symptoms and causes

Probable causes · in order

  • Loose or cut inlet hoseCommon

    The check LG asks for first. Visible by looking for drips at the threads or damage along the hose.

  • Internal leakPossible

    If the hose is fine and the code returns, water is escaping from an internal component. Only the technician can find it with the machine open.
