Haier Washer Error Code UNB — Unbalanced Load
What this means
Error code UNB on Haier washers indicates the control board detected excessive vibration from an unbalanced load during the spin cycle. The washer will reduce spin speed or stop spinning entirely to protect the drum bearings and suspension system. This commonly occurs when washing a single heavy item (like a comforter), when clothes bunch up on one side, or when the washer itself is not level on the floor.
Alternate codes: Unb, UB
Step-by-step fix
3 stepsRedistribute the laundry
Open the door or lid and redistribute the laundry evenly around the drum. If one heavy item is causing the imbalance, add a few towels to balance the weight. Close the door and restart the spin cycle.
Wet jeans, towels, and bed linens are the most common imbalance culprits. Spread them out rather than wadding them together.
Level the washer
Place a bubble level on top of the washer. Adjust the leveling feet at the bottom until the machine is level in both directions. Tighten the lock nuts to keep the feet in position.
A washer that is even slightly unlevel will vibrate more during high-speed spin, making UNB errors more frequent.
Check suspension components if recurring
If UNB occurs frequently with normal loads, the suspension springs (top-load) or shock absorbers (front-load) may be worn. Inspect them for visible damage or loss of dampening action.
Worn shocks on a front-load washer will leave oil marks on the floor underneath the machine.
When to call a professional
If UNB persists with balanced loads on a level machine, the drum bearing or spider arm may be failing, causing the drum to wobble. Professional disassembly is required for this repair.
