The Cons of Keurig K450

The disadvantages of the Keurig K450 are much fewer than the list of advantages. Some cons to consider about this brewing system are:

  • No multiple brewing options
  • System's needle can get clogged
  • Occasionally splashes
  • Only permits certain K-Cups

While some Keurig models provide multiple brewing options, the K450 system unfortunately does not.

The needle can become clogged, which potentially results in smaller brews. As it brews your coffee, it periodically splashes, which can be tedious but not a determining factor of its worth.

Lastly, the Keurig K450 has been claimed to only accept some K-Cups. Before purchasing K-Cups, research what cups and brands are compatible with the brewing system.

For the most part, if the Keurig label is on the K-Cup box then you should be able to utilize those cups. The cons are lacking in comparison to the pros.

However, each factor is dependent upon your own needs and preferences.


1: Time to Descale the Brewer!

Descaling the brewer is crucial for the brewer's performance. If you fail to descale the brewer periodically, calcium deposits accumulate in the coffee maker.

While these deposits are non-toxic, they can still affect the efficiency of the Keurig. Your brewer will alert you when it's time to descale, which is every three to six months.

First, you will need a mug and descaling solution. Empty the water reservoir and fill the reservoir with the solution. Then, fill the bottle up with water and pour into the water reservoir.

Remove the water filter as well. Make sure there are no K-Cups inside the brewer, and the system is powered off. Disable the Auto on/off feature during the descaling process.

Then, you will want to power the brewer on and dispense six ounces of hot water until the touch display asks for more water. Afterward, let the brewer stand for a half an hour with the brewer on.

After the thirty minutes, empty the reservoir and clean thoroughly. Fill the water reservoir back up to the maximum amount and repeat the cleansing brew process twelve times.

2: About the K-Cups

Are you tired of seeing the "Oops!" message on your touch display? This implies that the cup is incompatible with the system.

The Keurig K450 doesn't accept the K-Cups that don't have the Keurig design on their foil tops or the off-brand and refillable K-Cups.

3: How to Fix the "Oops!" Message

In order to remove the "Oops!" message, you will need to only purchase and use the newer Keurig approved K-Cups and K-Carafes. This video hack portrays how to trick the system to think your non-Keurig cup is a Keurig approved K-Cup (2). 

This requires at least one Keurig approved K-Cup. Do be aware that doing this hack could void your warranty.

Some places sell refillable K-Cups for the 2.0 Keurig brewers that could spare you financially overall (3). 

Typically, it's simpler to just purchase the many available Keurig-approved cups.
