Why is my drying taking longer than expected?

Extended drying duration can be caused by fluff collected in the drum, ambient temperature higher than 30°C, or insufficient air circulation in the room. Running the Drum Clean (cold) programme without laundry or detergent can remove accumulated fluff, and ventilating the room can help reduce drying time. Additionally, laundry that has not been spun at the highest possible spin speed before drying will retain more moisture and require longer drying times. (Page 51)
