LG Washer Error Code 1UB

The 1UB code on an LG washer signals that the upper washer drum has detected an unbalanced load during the spin cycle. The machine stops spinning to prevent damage to internal components. This is a load-related alert and is not typically caused by a faulty part. Redistributing the laundry inside the drum and restarting the cycle usually clears it.

Yes, the machine is designed to stop the spin cycle automatically when it detects an imbalance, which protects the drum, bearings, and suspension from damage. It is safe to open the door, adjust the load, and restart. Continuing to force repeated spin attempts with a severely unbalanced load over time could contribute to premature wear on suspension components, so it is best to address the load issue before restarting.

In the vast majority of cases, the 1UB error costs nothing to fix because it is caused by load distribution rather than a broken component. If the error occurs frequently even with properly sized loads, a technician may inspect the suspension or leveling of the unit, which could involve a service call fee typically ranging from $75 to $150 depending on your location, with parts costs varying if any components are found to be worn.

Press the pause button to stop the cycle, then open the washer door and reposition the laundry so weight is spread evenly around the drum. If one large item is causing the problem, add a few smaller items to help balance the load or remove the bulky item entirely and wash it separately. Once the load is redistributed, close the door and press start to resume the cycle.

A power reset may clear the displayed code temporarily, but the error will return as soon as the machine attempts to spin the same unbalanced load again. The correct fix is to physically redistribute or reduce the laundry inside the upper drum before restarting. Once the load is properly balanced, the error will not recur during that cycle.
