Ub

Ub — Spinning does not work / Unbalanced load.

Samsung · Washing Machines

What does Ub mean?

This code indicates that the spinning cycle is not working correctly, usually due to an unbalanced laundry load. The washer attempts to prevent damage by stopping or reducing spin.

Common Causes

  • Laundry is not spread out evenly in the drum
  • Washing machine is not on a flat, stable surface
  • Load is too small (e.g., only one heavy item like a bathrobe)

Repair Steps & Checklist

  1. 1

  2. 2

    Make sure the washing machine is placed on a flat, stable, and level surface.

  3. 3

    For very small loads, especially with single bulky items, add a few more items to help balance the tub.

  4. 4

    Restart the spin cycle or the entire wash cycle.
