Bauknecht Dryer: belt keeps popping off

Professional Repair Guide

What is this symptom?

If your Bauknecht dryer belt keeps popping off, it can prevent the drum from spinning even when the motor is running. This issue often arises from a loose or worn idler pulley, a worn drive belt, or drum support roller problems. Proper inspection and alignment are essential to restore functionality and ensure your dryer operates smoothly.
