Unb identifies an unbalanced load in documented Haier washer-dryers. Correct the distribution with the drum stopped before trying to restore spinning.
The Haier Appliances chart distinguishes this warning from internal faults. Recovery should follow the spin and dry options in your reference manual.
Check how the laundry was loaded
Pause and wait for the lock to allow opening. Untangle items and separate any load that has become wrapped inside a large piece. Check whether a single absorbent item is concentrating the load on one side.
Do not add laundry without checking the program capacity or increase the speed to override the warning. If the wash was followed by drying, confirm that phase limit as well: wash capacity alone does not authorize the same drying load.
If Unb returns with suitable, evenly distributed items, observe the machine’s support when it is stopped. Recurrence with different loads and correct support needs technical evaluation; by itself, it does not prove that the suspension or motor is damaged.
Indicate whether the warning prevents spinning or also entering drying; it helps explain which part of the process was left unfinished.
