Bosch Belt-drive / Washer Drive Belt 00439490, Replaces 00360829

Genuine Bosch OEM drive belt for washing machines. The belt connects the drive motor to the washer drive system or drum to rotate the basket.

Is This the Right Part?

Common Symptoms

• Washer fills and runs but the drum does not turn
• No spin or weak/intermittent spinning
• Squealing, slapping, or belt-slip noise during operation
• Visible belt fraying, cracking, stretching, or separation from the pulley
• Burning-rubber odor during operation

Check Before Replacing

• Disconnect electrical power before inspection.
• With the washer empty and powered off, check whether the drum turns freely by hand; abnormal resistance may indicate a problem beyond the belt.
• If access is provided by the appliance service procedure, visually inspect the belt for fraying, cracking, glazing, stretching, or displacement from the pulleys.
• Check that the belt is seated in the pulley grooves and that the pulleys rotate without obvious obstruction.
• If the belt is damaged or displaced, inspect the pulleys and surrounding area for visible damage or foreign material before replacing the belt.
