Query: don't try cleaning it either!!

I thought i'd follow the directions of this coffee machine for once, to prolong it's life. I tried running vinegar through it to clean it, and the next time i go to make coffee, it doesn't do anything, doesn't heat up, doesn't make a sound, nothing! I had it maybe a month, and got it as a gift, thus, no receipt, i was definately not impressed!
