Question: How to clean this model
Document: This is the third Keurig Coffeemaker that I have purchased. There was a super one day special for $69 for the Keurig model B40. I have two of the 60 models. I've been trying to buy more for my kids to have in their homes. There really no big difference in the models except the clock. My guests all love the choice of variety of coffee. It's easy and nothing to clean up. I must caution that the K-cups are expensive.
We've had this for one year and have enjoyed using it. It's fast and brews the coffee to a perfect temperature. We use the refillable K-Cups to save money, and by purchasing 2 refillable K-Cups we always have a clean cup ready to use. I bought the same model for my daughter and she had issues with coffee grounds in her coffee. By using the internet she found an easy fix, a fix I hope the company has made in their factory.
* * * * *O n e  L a s t  N o t e (May 31, 2013): this unit is about the simplest one (simple controls) that Keurig makes but, for people who appreciate the elegance of clean lines, this model is downright sculptural. Without the (fake) chrome and big, blue LED panel of other units, and with a simple but pleasing arc of small buttons and lights, this one deserves a design award.I love this coffeemaker.
My sister-in-law has the larger version of this machine which I encounterd on my last vacation. We have the industrial-size Kerug machines at work, which I love. Experiencing the home-version was a really nice surprise. I thought a smaller, less complicated, less expensive model would be sufficient for a single person, and I was pleased to find I made the right decision. This coffee maker is easy to use and easy to clean.
I love my Keurigs but our office is on our 3rd one in three years! We clean them regularly as directed and they are lightly used (two to three times a day max). We only buy them new and the bigger office model but have had horrible luck. Spoke with good friend about it and she said same thing on her lighter home use machine... she bought two in  2 1/2 years and says this is last one she will get if it doesn't last at least two years.
Another phone call to customer service again landed me a nice, seemingly helpful person who after much thinking and a run-down of all the pieces I had already tried to clean, etc. told me I must have a defective model and that I should ship the coffee maker back to them and they would repair or send a replacement (at my expense). I decided against that since I had already purchased the special edition. That one lasted me almost 6 months - again another Keurig that didn't work.
i gave this as a gift so i have no personal experience with this model, but my friend raved about it
The print and the buttons are large enough to see without squinting. There are no LED displays on this Keurig model.
This Coffee kit Is the Best It replace the older Model I had,So quiet and Great It also Came with 12 k cups
Used it less than a dozen times. Only worked half the time. Now doesn't work at all. Piece of junk. Very, very disappointed and would not recommend this model to anyone.
Answer: Descaling info is included in the instructions and the pod holder is removable. The instructions are easy to follow. If you use filtered water you shouldn't have to descale often. I have a brita pitcher which holds enough water to fill the reservoir.  I fill before bed and make as many cups as I want in the morning.
