Kenmore Elite HE5t Power and Errors

Hi experts! We have the "latest and greatest" washing machine which has worked wonderfully for the last 10 months until we got a F2 error message; then a F10 error message. Now, machine will not even power up although when we push the START button, it beeps. Nothing lights up now... just the little chirping beeps. Hubby unplugged, checked breaker box, checked filter after opening bottom, front kickplate. All looks well. Actually, everything behind that kickplate looked quite clean too.

It takes FOREVER to have a Sears tech to come out. Any suggestions? Hubby is very handy but not familiar with the new designs.

Thank YOU so much for your help!
