My Kenmore model # 110. 91551210 wahing machine, will not agitate or spin, in none of the cycles, it will fill with water and drain, I also can hear the moter running but it will not agitate or spin, what is the problem?:confused:

Try checking your drive coupling. It's usually a pair of plastic disks and a rubber bushing and is attached to the drive shaft on the motor. If it's the problem, it will probably be in pieces.

I found service tech diagnostic guides (PDF format) during an online search. This includes instructions on putting the dryer into test mode in order to check switches, etc. Here are the links:
