439490 Genuine Drive Belt for Bosch, Siemens Laundry Appliances, Washer or Dryer Drum Belt, BSH 00439490

Genuine BSH belt 439490, also 00439490, drives the drum in a Bosch or Siemens laundry appliance. We have it recorded simply as a drive belt, without the machine type or length, and BSH uses many sizes across its washing machines and dryers. The size code printed on the back of the old belt is the quickest way to compare, along with the parts list for your model's E-Nr.

Drum not turning but the motor runs?

A drive belt connects a small pulley on the motor to the drum, turning the motor's speed into drum rotation. Heat, age and heavy loads stretch and harden the rubber until it slips or snaps. Watch for a burning rubber smell, squealing as the drum starts, a drum that stalls with a full load, or a drum you can spin by hand with no resistance from the motor. Shredded pieces of belt on the floor of the cabinet confirm it.

Routing the new belt

Unplug the appliance, and turn off the water if it's a washer. On a washer the belt runs between the motor pulley and the drum pulley, while on a dryer it loops around the drum itself and is tensioned by an idler or the motor's weight. Photograph the old belt's path before removing it, route the new belt the same way, then turn the drum by hand to check it tracks straight.
