I bought this Coffee maker almost a year ago, and it stopped working, all I had to do was call the number on the bottom of the Keurig and answer a few questions and send them a picture of the model/serial number (because I did not have my receipt) and they sent me a new replacement machine.
When my K-Supreme Plus coffee maker stopped working during descaling, I called Keurig’s help line. Within a few minutes after listening to my description of the problem they offered to send me a replacement at no cost, which arrived a few days later. Excellent customer service.
This is our 3rd one in 12 months. They routinely stop working. Last one shorted out after 3 months while descaling in process. Keurig seems content to just keep sending us new ones every few months rather than fixing whatever is wrong with these machines.
