How to Clean Keurig Laser Lens

One of the most common issues with a Keurig coffee maker, especially in the latest models, is the ‘Oops’ prompt. Here’s how you fix it:

Step #1: Understand How the Keurig Works

When you want to learn about cleaning your Keurig coffee machine, you must learn about its working. A detailed impression of its working can help you understand why you need to learn how to clean Keurig laser lens.

Keurig K-Cups

The most interesting detail in the Keurig coffee maker is the use of K-cups. The K-cups are the pods, which contain freshly grounded coffee, assuring the best experience of coffee.

You can find different types of blends, roasts, and flavors of coffee with K-cups, which make your coffee refreshingly delicious.

The coffee remains fresh with the foil layer in K-cups safeguarding it against moisture. Just put the K-cup in your Keurig coffee machine and get hot, fresh coffee to drink.

Water Reservoir

The water reservoir is also undoubtedly one of the notable components of a Keurig coffee machine. It stores large quantities of water, and you don’t have to fill up water every time you needed coffee.

The coffee maker pumps water to heating chambers through pressurized hoses for optimal heating upon pressing the button.

How They Work Together

The heated water passes into a hose situated at the top of the brewer. Here, you can find an opening piece for inserting the K-cups. After placing the K-cup, you have to press and shut the opening piece.

Small pins would then pierce the K-cup and pour the hot water into the K-cup. Another puncture in the bottom plastic layer of the K-cup brings coffee to you.

This is how Keurig works, and the maintenance of each component is necessary for the machine’s proper functioning. Now, you might be wondering about the way you can solve the ‘Oops’ problem in your machine with this information.

Step #2: Take a Good Look At It

Many people forget to check the laser lens and end up ordering new K-cups. So, you need to take a close look at the laser lens in your coffee machine. Check whether it’s clean and use a light to find tiny debris or oil deposits on the lens.

You are likely to check your machine’s laser lens only when you come across a problem, which is not good. It is advisable to set a fixed schedule for inspecting and cleaning the optical laser lens.

For example, you can check the laser lens of your Keurig coffee machine every two days for any contamination.

Step #3: Prepare Lens for Cleaning

The next step involves preparing the lens for cleaning. The tiny dirt particles and coffee ground could be challenging to remove and damage the lens during cleaning.

So, you need to use a blower to remove the debris; even compressed air can also be helpful. A smoother surface always ensures that your Keurig laser lens is well prepared for cleaning. You could do this near a sink with a running faucet or somewhere you can clearly see the debris.

Step #4: Gather Supplies

When you are getting ready to clean up the laser lens in your Keurig coffee machine, you must have everything needed for the same. Try to have some detergent and wipes at hand.

Alcohol is a must, and you should also make sure that you are wearing gloves. It is also important to keep the lens upward before you start cleaning so that it doesn’t fall or break.

Step #5: Clean It Up

Dip a cotton swab in the cleaning fluid of your choice. As mentioned already, alcohol is a recommended cleaning fluid that is readily available and rightly suited for cleaning optics.

You have to place a drop of alcohol on the lens with the cotton swab and let it rest. After almost one minute, you can wipe off the lens with the swab. Finally, you can just use a moist cleaning cloth and wipe off the lens to complete the cleaning procedure.
