If you find some damaged garments coming from your washer don’t blame the machine.
Firstly, identify if you have washed clothing with zippers. If you leave the zippers unzipped, you may cause the damage. The zippers can snag the garments during the washing process. Remember, a large part of the washing process is friction between the drum and in between the garments.
The highly polished drum will not snag the garments. The only trap here is a very fine garment and a high spin speed may allow the material to pass through the water evacuation holes on some models of washing machines, and as the garment is removed a snag can occur. Always choose the lowest spin speed for fine materials. Or even better consider hand washing your cherished delicate items.
