If the electric connection is not the cause of the problem and an internal malfunction is the real culprit, I recommend contacting Keurig customer Care services or any other professional. For Contact information, move to the “ When to seek professional help” section.
Cause 7: Water Reservoir Magnet Alignment Is Wrong
If your Keurig coffee maker is turning off during the brewing process, it could be due to a misaligned or stuck magnet in the water reservoir. This magnet is responsible for detecting the water level in the reservoir, but it may become misaligned due to the vibrations produced during brewing. As a result, your Keurig may not be able to detect the water level properly, causing it to shut off instead of brewing.
Solution: Gently Tab The Water Reservoir
If you suspect that a misaligned magnet in the water reservoir is causing your Keurig to shut off while brewing, there are some steps you can follow to resolve the issue. First, try gently tapping the water reservoir near the magnet housing to see if that realigns the magnet. If that doesn’t work, give the reservoir a gentle shake to try to move the magnet. If the magnet still won’t budge, empty the reservoir and clean it with a mild soap before refilling it with water and trying to use your Keurig again.
Problem 10: Why Is My Keurig K-Duo Essential Coffee Not Hot Enough?
Waking up to a hot cup of coffee is a ritual for many coffee lovers, and it can be disappointing when your Keurig coffee maker fails to brew a hot cup. This can happen due to various factors that prevent the machine from brewing at the ideal temperature. Below we’ll explore why your Keurig K-Duo Essentials is not producing hot coffee and how you can resolve the problem.
Cause 1: Malfunctioned Water Pump
When the pump is not working, it can cause the heating element to shut off automatically before it reaches the desired temperature to prevent the machine from overheating. It can result in your coffee being brewed at a lower temperature than desired.
Solution: Repair The Water Pump
It’s advisable to contact Keurig’s customer support for assistance. Their skilled technicians can provide guidance and, if required, schedule a repair or replacement. You may even be eligible for a replacement if your Keurig K-Do Essentials is still within the warranty period. You can refer to this article’s “When to Seek Professional Help” section to obtain their contact details.
Cause 2:Use Of Cold Cup
Pouring hot coffee into a cold cup can result in the heat being transferred to the cup, causing the coffee to cool down quickly. It is more prevalent in the colder months when the temperature difference between the coffee and the cup is greater.
Solution: PreHeat The Cup
Preheating your cup helps to minimize this heat transfer, allowing your coffee to stay hotter for longer. It’s a simple trick that can make a big difference in your coffee-drinking experience, particularly if you enjoy it very hot.
These are the two methods you can use to preheat your cup.
Pour some water into your cup and microwave it for 30 seconds to a minute, depending on your microwave’s power. After heating the cup, dispose of the water and immediately brew your coffee into the preheated cup.
Boiling water method
Pour boiling water into your cup and let it sit for 30 seconds to a minute. After preheating the cup, dispose of the water and immediately brew your coffee into the preheated cup.
Cause 3: Keurig Is Clogged
A significant decrease in the efficiency of the water pump and heating element can occur due to the accumulation of limescale and clogs inside the coffee machine. This buildup can cause the brewing temperature to drop, resulting in a cup of coffee that is not hot enough.
Solution: Run A Descaling Cycle.
Running a descaling cycle is the most effective method to get rid of clogs resulting from limescale accumulation. Refer to the “Descaling Your Keurig K-Duo Essential” section in this article to learn about the detailed descaling process for your Keurig K-Duo Essentials.
Problem 11: Why Is My Keurig K-Duo Essentials Producing Weak Coffee?
If your coffee machine is making weak coffee, it could lead to dissatisfaction and disappointment in the quality of your beverage. It may not provide the desired level of caffeine to help you start your day, and the flavor may be lacking. It could result in a negative impact on your mood and overall coffee-drinking experience. Therefore, it’s important to identify the underlying causes and address them accordingly.
Cause: Poor Coffee Grounds
Poor-quality coffee grounds, such as those stored improperly or exposed to humidity, can often result in weaker coffee when used in reusable K-Pods.Suppose you observe a sudden decrease in the flavor or strength of your coffee. In that case, it is more likely caused by the coffee grounds than by any issues with the coffee maker. Environmental factors can speed up the oxidation process of the grounds, leading to stale coffee and weaker brews, even when using the same brand. If this occurs, try purchasing freshly roasted beans or grinding them yourself to ensure that the coffee retains its flavor.
Solution 1: Grind Only The Required Amount Of Coffee Beans
If you’re grinding whole coffee beans for reusable K-Pods or capsules, it’s recommended to grind the required amount for each Brew instead of grinding a large quantity at once. This practice ensures that the coffee remains fresh and flavorful for a more extended period. By grinding only the necessary coffee beans, you can ensure that every cup of coffee is fresh and delicious.
Solution 2: Store In An Airtight Container
Proper storage of coffee grounds is vital in preserving their freshness and flavor. When exposed to light, air, and moisture, coffee can quickly become stale and lose its aroma and flavor. It is important to store coffee grounds in airtight, opaque, and dry containers. It ensures that the coffee remains fresh and flavorful for a longer period.
Descaling Your Keurig K-Duo Essential
Minerals such as calcium can build up in your brewer and create a layer of scale that can impede your brewer’s performance. That’s why it’s important to descale your brewer every three months regularly or sooner if you experience low coffee volume or slower performance. Regularly descaling your brewer can help maintain its working capability and other internal parts that come in contact with water, ensuring that your coffee turns just as tasty as the first time you brewed it.
