What causes Haier Washer UNB?

Laundry bunched on one side of the drum, often a single heavy or bulky item such as a bath mat, rug, comforter or bed sheet. Too much laundry, or very heavy waterlogged items, for the selected cycle. Too little laundry: one or two heavy items with nothing to balance them. The washer isn't level or isn't on solid flooring, which Haier lists as a cause of strong vibration. Transport (shipping) bolts were not all removed after installation, which Haier lists for strong vibration while spinning. If it happens with every normal, balanced load, a mechanical problem such as worn suspension or a motor or sensor fault needs a technician to diagnose.

How do I fix Haier Washer UNB?

Pause the washer and open it once it unlocks. Pull the laundry apart and spread it evenly around the drum, untangling sheets and anything wrapped around other items. For a single large piece (carpet, bed sheet, tablecloth), lay it symmetrically in the drum, as Haier advises, or add one or two towels to balance it. If the load is very heavy and soaked, wring out the heaviest items by hand, put them back evenly, or remove part of the load. Close the door or lid and choose the Spin program to finish the cycle, which is the restart step Haier gives. Check that the washer is level and sits firmly on all four feet (rock it diagonally), and adjust the feet if it wobbles. On a newly installed front loader, make sure every transport bolt has been removed from the back of the machine. On a Haier combination washer/dryer, Haier says to spin on low speed, cancel the drying portion and redistribute the clothing.

When should I call a pro for Haier Washer UNB?

Unb appears with normal, evenly loaded laundry on a level washer with the transport bolts removed: Haier says to contact after-sales service or a qualified technician. The washer bangs, walks across the floor, or the drum sits visibly lower on one side, which can point to worn suspension or shock absorbers. In the U.S., you can schedule Haier service at haierappliances.com or call 1-877-337-3639.

Haier Washer UNB (Unb) Error Code: Unbalanced Load, Won't Spin Fast

Q: What does Haier Washer UNB mean?

On a Haier washer, UNB (shown as Unb) means the load is unbalanced. At the start of the spin the washer checks whether the laundry is spread evenly; if it isn't, it spins slowly to try to redistribute it, and if it still can't balance the load it won't go to full spin speed. Pause the washer, spread the laundry evenly around the drum (or add one or two items, or take some out), then run a Spin cycle. If Unb keeps coming back with normal loads, check that the washer is level and the transport bolts are out, then call Haier service. Haier uses Unb as an unbalanced load warning, not a part failure. Haier's Australian front-loader user guides (HWF75AN1/HWF85AN1/HWF95AN1 and HWF80AN1/HWF90AN1/HWF10AN1 families) list "Unb: Unbalanced load error. Check and balance laundry load in the drum. Reduce the load." Haier Malaysia explains what is happening: to avoid abnormal vibration, the machine tests whether the laundry is balanced at the beginning of the spin; if it is unbalanced, it spins at low speed to try to distribute the load, and if it can't, it does not go to full spin speed, so clothes come out wet. Haier Bangladesh groups Unb with E3 on some top loaders as the same unbalanced load error and adds leveling the machine. Haier Appliances' U.S. error chart for the Haier combination washer/dryer also lists Unb as "Unbalanced load" and says to spin the unit on low speed, cancel drying and evenly distribute the clothing. A single heavy item (a rug, bath mat, comforter or a pair of jeans with a few socks) is the classic trigger.

Parts that commonly fix it

Always match the part number to your exact model.

⚙

Anti-vibration washer pads

Can help on slippery or uneven floors once the washer is properly leveled. They don't fix a load that is bunched up.

⚙

Shock absorbers / suspension kit

Only if a technician confirms worn suspension. Match the part to your exact Haier model number.
