Whirlpool LGR7648KQ1 top loader washer

Washer fills, goes through wash cycle, but won't drian or spin. Timer continues to function normally after wash cycle, but when it gets to the drain cycle a motor hum (similar in sound like a stuck garbage disposal unit) happens for a few seconds followed by a slight "click" (motor circuit breaker?). The only noise after that is the sound of the timer continuing. After waiting awhile I can duplicate what I just explained -- nothing more. I've tried it several times with no success. Machine is five years old.
