This may not be the issue you are having with your machine, but it has restored mine to operating like new again. Nice, as I was ready to throw this thing off a tall building !!!
Sorry about the pixelated video in a few places. I tried everything I could think of to fix it, and I couldn’t. Windows Movie Maker glitch I guess.
UPDATE: My machine is now just over 3 years old and I have only had to perform this filter cleaning once. I am now VERY careful that the container I use to fill the machines reservoir, is extremely clean. I have always used filtered water from the dispenser on my fridge, but I suspect the container that I used to move the water from the fridge to the Keurig, was not always rinsed properly. I am glad that this video has helped so many people who are struggling with the same issue!
