Hi there. I just recieved my Keurig B40 coffee maker and no water will go into the machine when I fill the res w/water? It makes a lot of noise like it is going to brew a cup of coffee, but nothing comes out.The descale light will NOT come on. I have unplugged it for three weeks now and just tried again. No light by the descale. Never used this machine yet. Please help.
