Every time I try to descale my Keurig B60 with vinegar it plugs as soon as the vinegar solution enters the machine. Only a third of a cup actually makes it through the machine, then nothing.
I will leave it for 4 hours as recommended in the owners manual with whatever vinegar is in the machine to dissolve some of the hard water scaling, and then I have to bang, shake, turn upside down and whack it to get water going thorough it again.
So is there some advice on how to descale this machine? I do have hard water, so once every couple of weeks would probably be required, but it takes hours to get it "unplugged" and working again and it is a real pain.
