Bosch Dryer: not turning freely
What is this symptom?
If your Bosch dryer drum is difficult to turn by hand or fails to rotate freely during operation, you may be experiencing mechanical resistance. This issue can arise from several factors, including a broken drive belt, worn drum rollers, or obstructions within the dryer. Identifying the cause is crucial for restoring normal function and ensuring efficient drying performance.
