Samsung Washing Machine

I bought a Samsung Top loader in January 2014 from Hi Fi Corp. The machine stopped spinning, washing and rinsing Monday evening the 27/07/2015. I called Hi Fi Corp and they told me they will send it to Samsung will dispatch a technician to my house. I received a call from their Support department or customer services yesterday and the guy asked me if I checked my filters on the machine to see that it wasn't blocked. I said yes, he then instructed me to tip over the machine and to see if the bracket under the machine wasn't to tight. I don't understand and I don't know why I should check these things when my machine is still under warranty. I need for someone to call me or to send out a technician because I am not prepared to work on my machine and then get the blame from Samsung that I broke it.
