How can I get my Kenmore Model 110 to drain?

The timer advances on my Kenmore series 70 Model 110.82673810 but the water does not drain. There is a distant clicking noise as if the washer is trying to do something, but can't make the connection. When I manually turn the timer to agitate, it seems to do this part just fine. Then the timer advances by itself toward the spin cycle indicator and stops and there it stays. Any ideas?
