I have the same washing machine! This is the Whirlpool Electonic Controlled machine. A fantastic washer!
Do you hear the motor running but no agitation? Yup, it's the drive coupler. The part is available for about $15-20 or so and will take you about 15 minutes to repair. It's a very easy repair easy for a do it yourselfer. If you call someone out to do it they charge about $169.00.
These drive couplers are made of hard rubber. Some are nylon reinforced. They are there to reduce strain on the transmission. I'm willing to bet you have run some heavy clothes or blankets in your washer. If the motor is overloaded the drive coupler will break rather than the transmission or motor breaking. This is a good thing. Reserve your heavy stuff (blankets, comforters, rugs, etc.) for the coin op and you'll be good to go.
Here is an instructional video about how to do the job yourself.
BTW, your two screws will be on the front of the console at the bottom of the sides in a recess directly under the consoles chrome end caps.
