Common Mistakes to Avoid When Descaling Your Keurig

Using the Wrong Descaling Solution

One of the most common mistakes people make when descaling their Keurig machine is using the wrong descaling solution. Some people believe that using regular vinegar or lemon juice is sufficient, but this is not the case. Keurig machines require a specific type of descaling solution, which is designed to break down mineral buildup without damaging the internal components.

Using the wrong solution can cause corrosion or other damage to the machine, leading to a shorter lifespan and poor performance. Make sure you use a descaling solution specifically designed for Keurig machines, which can be purchased at most home improvement or kitchen supply stores.

Not Waiting for the Descaling Cycle to Finish

Another common mistake people make when descaling their Keurig machine is not waiting for the descaling cycle to finish. Keurig machines have a built-in descaling cycle that is designed to remove all buildups and make sure the machine is clean.

However, this cycle can take up to an hour to complete, and it is critical to let it finish before using the machine again. Failing to wait for the descaling cycle to finish can result in incomplete removal of mineral buildup, which can lead to poor performance and clogged lines.

Not Cleaning the Keurig Machine before Descaling

Lastly, some people neglect to clean their Keurig machine before descaling it. This is a significant mistake because descaling removes mineral buildup, and not dirt and debris that may clog the machine’s lines.

Cleaning your Keurig machine before descaling includes removing any old coffee grounds, wiping down the exterior, and cleaning the removable parts such as the water reservoir and drip tray. Cleaning the machine before descaling will ensure that the descaling solution can effectively remove mineral buildup without interference from other debris.

Preventing Future Power Issues with Your Keurig

Regularly Descaling Your Keurig

One of the most common causes of power issues with Keurig machines is mineral buildup from hard water. To prevent this from happening, it is essential to descale your machine regularly.

Descaling is the process of removing mineral buildup by running a mixture of vinegar and water through the machine. It is important to follow the manufacturer’s instructions on the correct amount of vinegar and water mixture to use. By regularly descaling your machine, you not only prevent power issues but also improve the quality of your coffee.

Using Filtered Water in Your Keurig

One of the easiest and most effective ways to prevent power issues with your Keurig is to use filtered water. Unfiltered tap water contains minerals that can build up and cause clogs in your machine. These clogs can cause your machine to work harder, eventually leading to power issues.

By using filtered water, you prevent mineral buildup, resulting in a clean and efficient machine. You can use a water filter pitcher or a faucet filter to ensure that the water you use in your machine is clean and pure.

Keeping Your Keurig in a Dry and Clean Environment

Another essential step in preventing power issues with your Keurig is to keep it in a dry and clean environment. Moisture and dust buildup can cause corrosion and electrical issues with your machine. Ensure that your machine is placed on a dry surface away from any water source or moisture.

Additionally, it is important to clean your machine regularly using a cloth and mild detergent. By following these simple steps, you can prevent power issues with your Keurig and ensure its longevity.

Keurig Won't Power On After Descaling


In conclusion, if your Keurig won’t power on after descaling, there’s no need to panic. Follow these simple steps to troubleshoot the issue, and you should be back to enjoying your favorite brew in no time. Remember to descale your machine regularly to keep it functioning properly and prevent any future issues from occurring.
