Tracey S Owens Cross Roads , AL January 07, 2020 Appliance: Bosch Washer WFMC5301UC/16 Bosch Washer Wfmc5301uc/16: Clothes were not spinning correctly and washing too long. How to replace Belt. We replaced the belt and shocks. The belt was very loose. We did put the new belt in hot water for about three minutes so it went on easier. Shocks were very easy to replace. Job took maybe a hour for both. Now the machine is performing like it use to. My bosch 500 series is now 14 years young.. 9 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
