Cracked or broken spider arms cause the drum to knock against the tub at high speed, producing loud metallic banging or grinding during the spin cycle.
A failed flange shaft causes the drum to run out of balance at speed, resulting in the machine walking across the floor or shaking violently.
If the spider arm is cracked, the drum loses its rigid mounting and can be felt wobbling when rotated by hand during inspection.
Samsung washers detect drum imbalance via sensors. A broken spider assembly can repeatedly trigger UE or Ub error codes even with a properly loaded drum.
The washer's safety system halts the spin cycle when severe mechanical imbalance is detected, often caused by a compromised flange shaft assembly.
💡 Pro Tip: How to Diagnose a Failed Flange Shaft Assembly
Your part is likely the culprit if you notice any of the following:
⚠️ Loud banging, grinding, or clunking noise during the spin cycle
⚠️ Excessive vibration or violent shaking at high spin speeds
⚠️ Drum wobbles noticeably or feels loose when spun by hand
⚠️ Washer stops mid-cycle with an unbalanced load error (UE / Ub code)
🔍 Diagnosis Tip: Pull out the drum and visually inspect the spider arms. A broken or cracked arm is immediately obvious. Also check for white powder or orange rust where the arms meet the drum shaft bore — this is the classic sign of galvanic corrosion failure common on Samsung front-loaders. If one arm is cracked, replace the entire assembly — never attempt to weld or patch a spider arm.
