Urgency

Low

Quick answer

On a Haier washer, Unb means an unbalanced load error. Open the washer when it allows, spread the laundry around the drum and, if it is very full, reduce the load before spinning again.

Safety first

Stop and check this first

  • Unplug the washer before moving it or adjusting the feet; do not use it if it walks across the floor while spinning.

Safe checks you can perform

  • Spreading the laundry
  • Amount of laundry
  • Stability and transit bolts

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Suspension and drum check
  • Do not attempt this professional task: Test spin

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. Suspension and drum check

    What they doThe technician checks the shock absorbers, springs and the drum rotation and checks the levelling with a spirit level.

    They must show youthe state of the shock absorbers and springs and the measured levelling.

    In writingthe cause, the part replaced with its part number and the reason.

  2. Test spin

    What they doAfter the check, the technician runs a spin with a normal load and checks it reaches speed without Unb.

    They must show youthe full spin without Unb.

    In writingthe test carried out, the result 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.

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. Spreading the laundry

    No special tools

    Who:
    you.
    How:
    once the door can be opened, untangle the laundry and spread it around the whole drum.
    Result that matters:
    the drum ending up balanced.
    If it was tangled or on one side:
    after spreading it, run a spin.
    If it was well spread:
    check the amount of laundry.
    Evidence to keep:
    note of what you found.

    Evidence: User manual Washing machine HW80-BD14979U1 / HW90-BD14979U1 / HW100-BD14979U1 · Manual de usuario Lavadora HW80/90/100-BD14979U1

  2. Amount of laundry

    No special tools

    Who:
    you.
    How:
    if the drum is very full, take some laundry out and spin again.
    Result that matters:
    ruling out overloading.
    If with less laundry it spins:
    it was the load.
    If with a normal load Unb continues:
    check the installation.
    Evidence to keep:
    note of the load.

  3. Stability and transit bolts

    No special tools

    Who:
    you, with the washer unplugged.
    How:
    gently push each corner to see whether the washer rocks and, if it is new, check at the back that no transit bolts remain.
    Result that matters:
    ruling out an installation that stops it balancing.
    If it rocks or bolts remain:
    level it with the feet or remove the bolts as the manual shows.
    If it is stable with no bolts and Unb continues:
    contact Haier's after-sales service.
    Evidence to keep:
    photo of the back and the feet.

What it means

Haier Europe's official manual (HW80/90/100-BD14979U1 washers) defines Unb as an unbalanced load error and asks you to check and balance the laundry in the drum and reduce the load. Haier Australia adds checking the machine is stable on the floor and the transit bolts have been removed. The washer measures imbalance before spinning and will not speed up if the laundry is badly spread. If Unb persists with the load spread, the machine level and the bolts out, the service checks it; the code alone does not point to a part.

Warnings and stop conditions

  • Loweditorial warning

    Unplug the washer before moving it or adjusting the feet; do not use it if it walks across the floor while spinning.

Symptoms and causes

Probable causes · in order

  • Laundry badly spread or tangledCommon

    A large item or tangled laundry on one side unbalances the drum; you see it when you open the door.

  • Too much laundryPossible

    Haier asks you to reduce the load; an overfull drum does not spread evenly.

  • Washer not stable on the floorPossible

    Haier Australia asks you to check the machine is stable; if it rocks when you push a corner, the feet are not level.

Does Unb still appear after these checks?
