A cracked or corroded spider arm allows the drum to shift off-axis, causing violent banging and clunking noises during the spin cycle. Replacing the spider restores balanced rotation.
When a spider arm fractures completely, the inner basket loses its connection to the drive shaft and either stops spinning or spins erratically with poor extraction performance.
A broken spider causes severe load imbalance that triggers the washer to vibrate excessively, 'walk' across the floor, and repeatedly pause with UE (unbalanced) error codes.
With a failed spider, the inner tub loses structural support and swings inside the outer tub, potentially contacting the door gasket or tub walls and causing leaks or further damage.
💡 Pro Tip: Is Your Spider the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Washer makes loud banging or clunking noises during the spin cycle
⚠️ Inner drum wobbles, swings off-center, or fails to spin at all
⚠️ Visible cracks or corrosion on the spider arms when rear panel is removed
⚠️ UE (unbalanced) or LE error codes that persist after redistribution
🔍 Tech Note: When replacing the spider, also inspect tub bearings (MAP61913708 / MAP61913707), bearing seal (4036ER2004A), and tub seal (4036ER4001B) — these parts often wear together. Replacing them at the same time prevents a second tear-down.
