Questions people ask
- What does UB mean on a Samsung washing machine?
- The washing has ended up lopsided in the drum, and the machine will not take it up to spin speed like that. Yes. Nothing is broken. The machine has stopped short of a spin it judged unsafe, which is exactly what it should do: an out of balance drum at full speed damages bearings and walks the machine across the floor. Start here: open the door and redistribute the laundry.
- What does UB mean on an LG washing machine?
- The load is unevenly spread, so the machine has stopped short of the spin. Yes. Nothing is broken. The machine tries to correct the balance by itself, up to three times on most models, before it gives up and shows the code. Seeing it at the end of a cycle usually just means the laundry has come out wetter than it should. Start here: open the door and spread the load out.
Do not see your machine? We publish a brand only once its codes are confirmed against manufacturer documentation and a second independent source. That is slower than guessing, and it is the whole point of the site.
This is not a coincidence of one code: we compared every code that appears on more than one brand and found that several mean the opposite depending on the badge.
