Washer makes loud banging or knocking noises during spin

Safety first: Keep children and pets away from a violently shaking washer. Unplug before inspection.

Step-by-step checks:

• 1. Rebalance load: Pause the cycle, redistribute clothes evenly, and remove heavy single items.
• 2. Level the washer: Adjust the leveling feet so the washer is stable and does not rock. Lock the jam nuts.
• 3. Inspect shocks (front-load): Remove front or rear panel and check shock absorbers for oil leakage or broken mounts. Replace in pairs if worn.
• 4. Check suspension springs (top-load): Inspect tub suspension rods or springs for stretching or breakage. Replace as a set if damaged.
• 5. Counterweights: Ensure concrete or cast-iron weights on the tub are tight and not cracked.

When to call a technician: If the drum has excessive play or grinding, the tub bearings may be failing and require specialized tools to replace.
