Query: Have same problems as others have mentioned

As others have mentioned, my Keurig is also brewing only a partial cup. I also have owned my Keurig for about six months & it worked perfectly for that time. I received it for Christmas 2010 & in May 2011, it started only brewing a partial cup & water gets pumped back into the resevoir instead of into the coffee cup. We use filtered water only, so I don't know why it would have anything to do with scaling. I emailed Keurig approx. a month ago to their customer service dept & have not gotten a response. I'm sure they're inundated with emails about this problem. Do not buy this product unless you like replacing your coffee maker every six months. VERY DISAPPOINTED !!!!
