I also have the B70 Plat and I'm trying to remember if I've had it one or two years now. I'm thinking two.... I'm having trouble with mine intermittently - short cup, NO cup, very noisy...happening more and more often. The machine has only once 'asked' to be descaled and I did buy a commercial descaling product for it. I have also, along the way, used white vinegar from time to time to help it along. Even with the commercial product, it doesn't seem as if problems are fixed or noisiness is reduced for more than a cup or two so I suspect it's time to start shopping for a replacement machine. When I first got this one I had planned on only using distilled water in it to avoid mineral build-up and, even though it came with a My K-Cup, my preference was to mainly use the K-cups. However, my dear hubby felt that filtered water from the refrigerator would be fine for the machine (strike one) and then later, decided that the K-cups were too expensive to use all of the time and decreed that we should simply use ground coffee in the My K-cup (strike two). It is my humble (and perhaps overprotective) opinion that these two issues are leading to an early demise of my beloved Keurig. I'd like to buy another and my husband does also love the coffee that the machine makes but I am concerned about running into the same troubles all over again with a new machine. Looking at the mini or the Mr. Coffee/Keurig machine but I suppose I'd better post elsewhere, my questions regarding these machines. I would like to know though, do any of y'all think the type of water and the way we've been using the machine has been the problem? Also, have any of you tried using CLR as a descaler for your Keurig?
