Dryer vibrates excessively or moves across the floor during operation.

Safety first: Unplug the dryer.

Level the appliance:

• Adjust the leveling feet so the dryer is stable and does not rock.
• Use a spirit level on top of the dryer front-to-back and side-to-side.

Check load and supports:

• Avoid very small or very heavy single-item loads.
• If vibration persists, inspect drum supports and rollers for wear.
