Kenmore Elite HE4: Don't Make My Mistake

I bought this machine last year. It worked for one year. And just when the warranty expired we started having problems with the door lock and panel signals. I had to call the Sears service people three times which cost us money. While I waited for the fix I also had to wash my cloth in a local laundry mat. I already spent half the cost of the machine on the service calls and laundry, and I wish I did my research first on this machine. I found many people on the internet complaining about this particular model.
