Washer-dryer combo makes loud banging or knocking noises during spin.

Safety first: Do not touch or lean on the machine while it is violently shaking. Unplug the unit before making adjustments.

Steps to correct:

• Redistribute load: Pause the cycle, open the door, and rearrange clothes evenly around the drum. Avoid washing single heavy items alone.
• Check leveling: Place a level on top of the unit. Adjust the front and rear feet until the bubble is centered front-to-back and side-to-side. Lock the feet with the jam nuts.
• Verify shipping bolts: On recently installed units, check the rear panel for any remaining shipping bolts that secure the drum. Remove them according to the installation manual.
• Inspect suspension (advanced): Remove the top cover and gently push down on the drum. If it bounces excessively or clunks, the suspension rods or dampers may be worn and should be replaced.

When to stop: If noise persists despite proper leveling and balanced loads, internal components like bearings or shocks may be failing; professional diagnosis is recommended.
