Zanussi dryer makes loud banging or thumping noises during operation.

Safety first: Unplug the dryer before removing panels or reaching inside the drum.

• 1. Check load: Stop the dryer and redistribute the laundry. Large heavy items can cause banging if they clump together.
• 2. Inspect drum baffles: Look inside the drum at the lifters/baffles. Check for loose screws or foreign objects (coins, buttons) trapped underneath. Tighten screws and remove objects.
• 3. Spin drum by hand: With the dryer off, rotate the drum. Listen for grinding or scraping noises that indicate worn rollers or bearings.
• 4. Access rollers and bearing: Remove the front panel and drum (model dependent) to inspect the front felt seal, support rollers, and rear bearing. Replace any rollers that are flat-spotted or noisy, and replace a worn rear bearing kit if fitted.
• 5. Check felt seals: Worn or detached felt seals can cause metal-on-metal contact and noise. Replace seals and ensure they are glued or clipped correctly.
• 6. Professional help: Drum removal and bearing replacement can be complex; consider a technician if you are not experienced.
