Possible Causes

Flat-spotted drum rollers from long-term storage, Worn drum bearings, Loose drum baffles, Uneven load distribution

How to Fix / Troubleshooting

Safety first: Unplug the dryer before internal inspection.

  • Check load: Stop the dryer and redistribute the clothes. Avoid drying a single heavy item alone.
  • Inspect drum baffles: Open the door and check that internal drum lifters/baffles are secure. Tighten screws or replace loose drum baffles.
  • Check rollers and bearings: Remove panels and inspect drum rollers and rear bearing (if fitted). Replace worn components.
  • Level the dryer: Ensure the dryer is level on the floor. Adjust feet as needed to prevent excessive vibration.
