Unbalanced load — washer cannot distribute the load for spin

The washer tried to spin but the drum load is unevenly distributed, so it fills with water and re-tumbles to redistribute the items rather than risk a violent off-balance spin. After several failed balance attempts the cycle stops with UB. A single heavy item (bath mat, hoodie) or a not-quite-level machine is the usual cause.
