I was pleased with the customer care person that helped me with my problem. The descaling feature didn't correct itself after multiple times of doing the process. Since my coffee maker was under warranty they replaced same model immediately at no charge. I received the coffee maker in a few days.
My Keurig stopped working completely as if it had shorted out internally. I heard a strange sound after turning it on. I called to tell Keurig that I had registered my coffee make earlier in the year and had the receipt still. I was advised to send copy of the receipt on an email they sent to me. I called 2 times to ask where my replacement coffee maker was and finally got someone to order it for me. The good news is that I got a brand new Keurig Supreme two weeks later.
