Keurig K55 Review
The Keurig K55 is one of the most reliable single serve makers on the market. It is reasonably priced, and it produces great tasting coffee due to it perfect brewing temperature. Great addition for smaller households of up to two people.
- Auto off timer
- Large water reservoir
- Compatible with all K-Cups
- Simple to use
- Brews multiple cup sizes
- No programmable clock
Keurig K55 is certainly one of the simplest Keurig models to date. It does not have a spaceship-like touch LED screen, temperature control settings, high altitude settings, or even a clock. It also does not cost a fortune.
But, wait, so why would I ever want to purchase the K55? I’m glad you asked.
Just because the K55 unit does not come equipped with all the modern day gadgets, doesn’t mean it will not brew a good cup of coffee. In fact, considering that it is half the price of other Keurigs, this is a great entry level single serve coffee maker for any home.
Let’s have a closer look and see what Keurig K55 has to offer.
Setting Up Your Keurig K55
The first item you take out of the box should be the Use and Care Guide. The step-by-step instructions are all you need in order to properly set up and plug in your machine.
Even though, the entire setup can be completed in a couple of minutes, we recommend you do the following first:
- Soak the charcoal filter for up to 5 minutes.
- Rinse the stainless steel mesh.
- Wash the filter holders.
- Set the replacement date dial to either 2 or 3 months – whatever you decide is best.
It is always advisable to do some cleaning and maintenance on any coffee maker that has just come out of the manufacturing plant.
Keurig K55 Design & Features
If you are tired of having stainless steel looking appliances around the kitchen, you will be glad to know that the K55 is available in black or rhubarb (cherry red) colors. The only stainless steel parts are found under the hood. And the hood, of course, is made out of plastic. Much like any other budget-buy coffee maker.
The control panel is located at the top right side of the unit. It consists of 5 light indicators and 5 buttons (Power, Auto-Off, and 3 cup size selectors).
The indicators are easy to read and understand. The top one is Add Water and it notifies the user when the level of water in the reservoir is too low. This is also the number one reason why the brew might refuse to start.
Next, you have the Descale indicator that lights up whenever the machine is in need of descaling. The recommended time is every 3-6 months, and having this reminder on the unit really helps.
The heating light only turns on when the machine is heating up and preparing for a brew. The light should be off at all other times.
The auto-off indicator comes with its own button, and we recommend you always keep it turned on. This function will automatically turn off the K55 unit if it is not used for 2 or more hours. It helps preserve the life of the machine, as well as helps save a little bit of energy in the household.
Last, but not least, is the POWER button. Pretty self-explanatory, and quite necessary for the brewing process.
The only reason this is not the simplest ever control panel is that some Keurigs come with just one BREW button.
Keurig K55 Water Tank
The reservoir holds 48 ounces of water. This is good, because most single serve coffee brewers of this price range, usually come with smaller tanks. It is not comparable to K575’s 80oz water tank, but it is much better than Nespresso Inissia’s 24-ounce reservoir.
The reservoir is made of BPA plastic, and it is easily removable. This will allow you to quickly fill it up and put it back.
NOTE: We always recommend you rinse the water tank before refilling it. But, this, of course, depends on how often you change the water in it.
Performance & Functionality
Keurig K55 runs at 1500 watts and standard 110 or 120 volts at 60 Hz. This is the North American standard, so if you live in Europe, for example, you might need to invest in a transformer.
The machine brews K-Cup pods at 193 degrees Fahrenheit, and Vue and K-Carafe pods at 197 degrees Fahrenheit. Which is the ideal temperature for extracting coffee?
Speaking of brewing, the K55 offers 3 cup size options – 6oz, 8oz, and 10oz. Unlike other Keurigs, it does not have a carafe option. However, you can use any brand K-Cups, including the refillable ones. This gives you all the taste and variety in the world of coffee.
NOTE: The K55 model is not compatible with k-mugs, k-carafe pods.
Warming up the machine and getting your first cup of coffee in the morning takes a little less than 5 minutes. The brewing process itself is quite fast – 30 seconds for 6 oz. However, when you first turn on the unit it will take around 4 minutes to warm up.
The good thing is that it only takes 15 seconds to heat up for the next brew.
Cleaning & Descaling Your Keurig K55
I think the only person I know who is fond of cleaning anything, is Monica from the old but gold TV series Friends. And she was a fictional character!
Cleaning the outside of the K55 is easy. It takes 20 or so seconds and it can be done with a wet piece of cloth. Honestly, I was surprised that coffee did not stick to the plastic as much as I thought it would.
The more tedious cleaning is associated with the internal parts of the unit. Luckily, this needs to be done only twice a year. But, it is necessary in order to assure a higher quality of the brew.
Instead of taking the entire unit apart, I recommend you clean up the stainless steel mesh, and then just do a descaling of the K55.
All coffee makers get calcium deposits (also known as scale) after a certain time. Cleaning that scale by hand is a dreary task. Luckily, the K55 and most Keurigs come with automated functions. So, here is what you need to do:
- Fill up the water reservoir with 10 to 12 ounces of descaling solution or white vinegar (both are available in most stores).
- Place a carafe or some kind of water holding pitcher on the drip tray. Make sure it has enough liquid holding capacity.
- Hit the brew button and relax for a minute. Once the descaling solution is dispensed, throw it out.
- Repeat this process with another 10 ounces of the solution or white vinegar.
- Let the brewer cool off for 30 or so minutes.
- Add a full tank of water and let it run. Dispense the water. You can repeat this procedure 3 times. It will assure no solution or vinegar is left inside the brewer.
Do NOT use any pods during this process.
