Keurig K55 K-Classic Review

Keurig K55 K Classic Review

Rated by Jennifer

Rating: 3.7 Stars

Now I return to the classics yet again…This review is for the Keurig K55, also labeled as the K-Classic, as it’s labeled. It’s one of the more recent successors in the “Elite” series, and if you’ve kept up with my reviews on those, some of the information here may seem familiar.

Right now it’s widely available in most retailers and I had a chance to check out the Keurig K55 up-close and personal at my local Krogers to further enhance my recommendation of it. If you have previously owned one of Keurig’s older models (e.g., the Platinum series), you might view this model as a stepdown.

Keurig K55 Features

As one of The K45 Elite’s biggest successors, the K55 has all of the styling, function and general appearance of that particular generation.

  • Included are 3 brew sizes (6, 8, and 10)
  • Average brew time – ready in one minute
  • Auto-shutoff
  • A 48 oz removeable reservoir
  • Three indicator light indicating actions Descale, Preheating and Add Water

And yes, it does have open-platform K-cup adaptability (yay!)That being said – standard ized pods only…sorry, but you cannot use the “K-Mug” and “K-Carafe” pods with the K55 (those 2 are strictly made for operation with the 2.0 series)

What’s Included?

With the Keurig K55, you will also receive a bonus sampler pack of 4 -ups (one is hot cocoa, everyone claims), start guide, 1 year limited warranty. I was under the impression that a water filter kit was also part of the deal, but I don’t see it explicitly stated anywhere. I did hear a few comments from consumers that they were trying out one of the 1.0 filters and found that it didn’t fit, or words to that effect.

keurig k55 reviewDimensions

Ok…dimensions: 13.3″ height, 10.1″ width and 13.2″ depth are provided on the sales page;this one somehow different in which an array of images is shown including details from the box, so I’m taking it as accurate. When the kcup chamber is fully opened the height moves to 17.6″ if you are checking cabinet space first.

The three-prong power cord reaches a length of 32″ (nothing said about it being retractable-yet) And perhaps the biggest biggie you are waiting for if you’re a traveler or commuter – yes, the K55 is good at accommodating taller travel cups; just take into account the max height of a cup that space will permit is 7.1″ with the drip tray removed.

Keurig K55 Colors Available

The main listing page shows choices of a Black or Rhubarb (a pretty shade of reddish-pink). Since the K55 is a successor of the K45 Elite which also included White and Patriot Blue, I assumed that those colors, too, are available in the K55. They are, just on different listings. (I had to enter the color name after Keurig K55 in the search bar…)

Drip Tray

This part is well made, with a one-inch depth, the drip tray will hold up to 8 oz of overflow for all of those “oopsies” out there. The drip tray plate has this neat little design on it with a star shape cutout, which you stick your thumb into to pull it out easily. Also it is top rack dishwasher safe.

Remove the drip tray and you can easily segue in one of the proprietary tumblers.


Just like most all of the “Classic/Elite” series goes; the K55 has a 48 oz reservoir, which will make a day or evening of brews pretty much hassle free. To remove the reservoir for easier refilling, simply push up and out. The lid comes straight off. If you look to the interior side of the reservoir that doesn’t show when it is in place with the machine, you can see the max fill line near the top.

There is also a small oval shape space in which the water filter is inserted (it kind of faces the front). This water filter is the same black model with the wheel at the top that you can set the monthly reminder to.

In case you’re wondering, the reservoir doesn’t light up (I wish it did – I love that feature)Also, what is up with this…..As per the user manual, you are recommended to use only bottled or filtered water with our brewer (some people have used distilled water with no problem,, which is fine, since the K55 doesn’t have those 2.0 sensors that mis-read due to distilled water’s non-mineral state.

Keurig K55 Buttons and Controls

Basic operation includes a control panel on the left side There are three indicator lights, power button, and auto-off button. No LED window, touchscreen or any of that.

I’m puzzled when I look at the user guide, however – and I see the button/icons labeled as “5.25” “7.25” and “9.25”…Now I get that their respective even numbers are easier to remember in other locations, but it’s got the potential to confuse people.

What is the point of increments, when whole numbers are easier to remember? Most people know the brew sizes by their respective whole numbers…6, 8, and 10.

Decoding the Control Panel Colors: “Add water” – Blue light, “Heating” – Red light, “Descale” – Red light, Auto off – Green, and power – Green

Once again, pretty reminiscent of the K45 Elite, the K or B40, pretty much, in terms of button and light operation. If you have ever owned one of those you may need no further explanations.

Keurig K55 and the K50 Compared

If you’ve been shopping for awhile and were looking into the K50 which preceded this one, you may have wondered if it differs all that much from this one. In a nutshell, no.

The K50 model simply was released first and is a little bit smaller in size and weight.If you’re browsing, you may find that the K-Classic is labeled K50 and K55 so if you happen to pick up the former in error, pretty much all of what is discussed here will still apply.

Same thing if you see “B50” or “B55” as well 🙂

Keurig K55 Consumer Reviews and Ratings

Well, the news seems happy….but on average the K55 reviews are mostly good or satisfactory, but, and emphasis on but…..there are also a lot of unsatisfied comments and remarks as well. With the large quantity of comments in general (surprising since this model hasn’t been out as long as you might think) combing through them all would be time consuming, but there ‘s enough of a pattern established to make a determination.

What’s good….Don’t have to worry about DRM restrictions. The way the front panel slopes down just so slightly, making it easier to read and punch in selections (I agree with that one too) few temperature complaints (this one does not have temp control by the way ) enjoy the speed and convenience.

But then….One two and plenty of reviews by some flabbergasted consumers who have experienced that all too dreaded premature machine failure. Why is this? Happy and thankful mine is not having these problems….Quality control perhaps?

Kind of made me reminisce about some of those older early 2000s models that had that nice chrome finish….Dang, I wish I could report something better, but it is telling me that the K55 should go into the “good…but you can do better” category.


  • You can use non-Keurig labeled pods
  • You can use refillable cups
  • Expedient operation
  • Easy to refill reservoir
  • Has auto-off
  • Accommodates tumblers (<7″) easily


  • Reliability overall could be better
  • Cannot be programmed
  • Does not have temp control
  • Standard water filter does not fit


The price on the K55 is comparable to the older member of its generation. Prices varied depending on the color too…At the time of writing it looked like all of them except the Patriot Blue were under $100. In succession from highest to lowest, it looked like, Patriot blue, White, Rhubarb, Black.

Besides that, your only upkeep expenses, white vinegar for periodic descaling and if you prefer to use your own coffee to save money, you definitely can with the K55 as it will take most of the refillable cups on the conventional market.

keurig k55 reviewSummary

Well…Is this a good fit for you? It depends. It’s somewhat basic looking, doesn’t have that high-gloss look. That’s just me…I’m a sucker for shiny things, yes I know they show fingerprints, but hey that’s the breaks. The K55 will pretty much do what you want or need if that is to get a quick cup of coffee without frills.

If you’re still with me, and you like the design overall, I think you can get far better reliability in a Keurig machine if you take a look at the Office Pro, whose design is very similar in appearance, but you also get benefits like the option to drain the internal tank, and a stronger pump in general.

Overall, this is why I give it a score of abut 3.7 – it’s fair, not the best but not the worst either. It will suit your needs if you’re a college student in need of semi-continuous caffeination, someone who needs a commuter cup to take to work every day, or someone looking for the right coffee addition to their desk or personal office space.
