Risk level

Medium

Proceed carefully and stop if the check is unclear.

Urgency

Medium

Quick answer

LG uses nE when the Vario pump impeller does not spin normally, sometimes because dishes touch it. Rearrange the load so nothing rubs that area and restart the dishwasher. If nE persists, LG asks for a service technician inspection.

Safety first

Stop and check this first

  • The Vario pump sits under the tub and runs on mains power: do not dismantle the base to reach the impeller; your part ends at arranging the load.

Safe checks you can perform

  • Dish arrangement
  • Restart
  • Test programme

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Vario pump check

What a technician must be able to justify

A technician is coming

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. Vario pump check

    What they doWith the appliance unpowered, the technician inspects the impeller, the Vario pump motor and its connection, and measures against LG specification.

    They must show youthe blockage found or the measurement against the specification.

    In writingwhat was checked, the result and the reference of any replaced part.

  2. Test wash

    What they doAfter the repair, the technician lets a programme finish and checks nE does not return.

    They must show youthe finished programme with no code.

    In writingthe test and the date.

Before accepting a part or repair

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

Checks and evidence, step by step

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

  1. 1

    Dish arrangement

    No special tools

    Procedure

    Who:
    you.
    How:
    switch the dishwasher off, open the door and check the lower rack: nothing hanging towards the base, nothing touching the arms or the bottom.
    Result that matters:
    a load that does not touch the impeller area.
    If something was hanging or touching:
    rearrange it; that was the likely cause.
    If everything was well placed:
    restart anyway to rule it out.
    Evidence to keep:
    a photo of the load before moving it.

  2. 2

    Restart

    No special tools

    Procedure

    Who:
    you.
    How:
    switch the dishwasher off, unplug it or switch off its isolator for a moment and switch it back on.
    Result that matters:
    a restarted appliance with the corrected load.
    If the code is gone:
    run the programme again.
    If nE is still there:
    request service.
    Evidence to keep:
    the time of the restart.

  3. 3

    Test programme

    No special tools

    Procedure

    Who:
    you.
    How:
    run a programme and listen for normal washing or a stop with the code.
    Result that matters:
    whether the cycle finishes without nE.
    If it finishes:
    that solves it.
    If nE returns with a correct load:
    call a technician; do not keep running programmes.
    Evidence to keep:
    the point in the cycle where nE appeared.

What it means

According to the LG guide, nE means a Vario pump issue: it appears when the impeller does not spin or does not spin normally, which can happen when dishes touch it. LG says to reorganise the dishes and restart the appliance; if the error persists, a service technician inspection is needed. The code does not say whether the load is stopping the impeller, something is stuck or the pump motor has failed: the technician separates that.

Symptoms and causes

Probable causes · in order

  • Dishes touching the impellerCommon

    This is the cause LG gives. You recognise it because nE clears once the load is rearranged and the appliance restarted.

    Evidence: [LG Dishwasher] Guide to Error Codes

  • Vario pump or motor faultPossible

    If nE returns with the load correctly arranged, the impeller is not spinning for an internal reason. LG asks for a technician.
