Samsung Washer Error Code UE (or Ub / dc) - Unbalanced Load

Low Severity

The electronic vibration sensor detected an uneven weight distribution in the drum during the high-speed spin cycle, pausing the spin to prevent severe structural damage.

Appliance: Samsung Washing Machines

Estimated Time: 5-10 minutes

Tools Required: Bubble level, adjustable wrench

⚠ Common Symptoms & Observations

Washer bangs loudly, vibrates violently, or shakes excessively; timer jumps back from 9 minutes to 15 minutes repeatedly; machine refuses to reach full spin speed.

🔍 Root Causes for Code UE / Ub / dc

Washing a single heavy item (like a heavy bath mat, comforter, or soaked jeans) that bunches on one side
overloading with too many bulky items
washer feet are unlevel on the floor
worn-out suspension shock absorber rods.

🔧 Step-by-Step DIY Troubleshooting & Fix Guide

Pause the cycle and unlock the door once the drum stops moving.

Rearrange the clothing evenly around the periphery of the drum. If washing a single heavy blanket, add 2-3 damp towels to balance the opposite side.

Check that the washer is level by placing a bubble level on top. Adjust the leveling legs at each corner using a wrench until all 4 feet touch the floor firmly with no rocking.

🔄 Master Reset Procedure for Samsung

Calibrate the washer: With the drum empty, press and hold the 'Temp' and 'Delay End' buttons simultaneously for 3 seconds until 'Cb' appears, then press Start to run the auto-calibration cycle.

Technician Tip: If the error code reappears immediately after a hard reset, the control board has detected an active electrical open circuit or failed component that requires physical inspection.
