I have a Kenmore 80 series washing machine model number 110.29892990. It got off balance and now it won't agitate. It will fill up with water and stop. How do I fix it?

If the washer fills up and you hear the motor run but not agitate, you probably broke the drive coupler, not uncommon from overload or from the drum being off balance. You tube has details on how to replace the part. Not too difficult and the part is less than $20.
