Kenmore washing machine agitates slow. - Washing Machines

Hello & Welcome to FixYa

I don't think it has to do with any sort of belt instead it seems that something is stuck under agitator or the agitator needs replacement. You can view this video if you want to replace it yourself:

Please get back to me if you have any other questions.

Hello,
Your washing machine belt is the cause of the problem. It is the reason your washing machine is agitating slowly.
You need to either tighten the belt, or replace it. Make sure you don't tighten the belt too tight.
Good luck.
