A blinking light on your Keurig K35 can be a frustrating sight, especially when you’re craving that morning cup of coffee. These blinking lights are usually indicators that something isn’t quite right with your machine, preventing it from brewing. Fortunately, most of these issues are easily resolvable at home with a bit of troubleshooting. This guide will walk you through the most common causes of a blinking light on a Keurig K35 and provide step-by-step instructions on how to fix them.
Understanding the Blinking Light
The blinking light on your Keurig isn’t just a random occurrence. It’s your machine’s way of communicating a specific problem. The most common blinking light is often associated with a lack of water, but it could also indicate a more complex issue. Before you start diving into solutions, it’s important to understand the possible reasons behind the blinking. This understanding will help you diagnose the problem more efficiently.
Identifying the Specific Light
Keurig K35 models typically have a few lights that could be blinking. The most common is the “Add Water” light. However, other lights might be flashing as well, sometimes simultaneously. Pay close attention to which light is blinking and whether it’s a steady blink or an erratic one. This detail can offer clues about the underlying problem.
The different lights usually indicate:
- Add Water Light: Low water level or a problem with the water reservoir.
- Brew Light: Machine is heating up or experiencing a brewing error.
- Descaling Light: Indicates the need to descale your Keurig.
It is always best to consult the user manual, which will provide insight into how to decipher the different signals given by these indicator lights.
Troubleshooting Steps: The Add Water Light
The “Add Water” light blinking is the most frequent problem K35 owners encounter. This issue arises when the machine doesn’t detect enough water in the reservoir to brew a cup. There are several reasons why this might happen, even if the reservoir appears to be full.
Checking the Water Reservoir
The first and simplest step is to ensure the water reservoir is actually full. It might seem obvious, but sometimes a quick glance can be deceiving. Remove the reservoir completely, rinse it out to eliminate any potential debris, and refill it to the maximum fill line. Also, check the reservoir for any cracks or damage that could cause water to leak out.
Ensuring Proper Reservoir Placement
Proper placement of the reservoir is critical. The Keurig uses a sensor to detect the water level, and if the reservoir isn’t seated correctly, the sensor might not register the water. Make sure the reservoir is securely attached to the base and that there are no obstructions preventing it from making full contact. Apply gentle pressure to ensure it’s properly seated.
Cleaning the Water Reservoir and Filter
Mineral buildup and debris can interfere with the sensor’s ability to accurately detect the water level. Remove the water filter (if you use one) and clean both the reservoir and the filter housing with a mild soap and water solution. Rinse thoroughly to remove any soap residue.
Inspecting the Water Inlet Needle
The water inlet needle is a small, sharp component that punctures the K-Cup pod. Sometimes, it can become clogged with coffee grounds or mineral deposits. A clogged needle can prevent water from flowing properly, even if the reservoir is full. To inspect the needle, carefully open the brew head and look for any visible obstructions. Use a paperclip or a needle-cleaning tool to gently clear any debris. Be very careful not to damage the needle during this process.
Checking the Float Mechanism
Some Keurig models have a float mechanism in the reservoir that indicates the water level. If this float is stuck or obstructed, it can send incorrect signals to the machine. Empty the reservoir and inspect the float. Gently try to move it up and down to ensure it’s moving freely. If it’s stuck, try to dislodge it with a gentle shake or by running water over it.
Troubleshooting Steps: Other Blinking Lights
While the “Add Water” light is the most common culprit, other blinking lights can also indicate problems. Understanding what these lights mean and how to address them is crucial for keeping your Keurig K35 running smoothly.
Addressing the Brew Light
If the brew light is blinking, it usually signifies that the machine is either heating up or experiencing a brewing error. If the machine is simply heating up, wait a few minutes to see if the light stops blinking and the brewing process begins. However, if the light continues to blink, it could indicate a more serious problem.
A common cause of a persistent blinking brew light is an improperly inserted K-Cup pod. Remove the pod and make sure there are no obstructions in the pod holder. Reinsert the pod, ensuring it’s seated correctly, and try brewing again.
Another possibility is that the machine is overheating. Unplug the Keurig and let it cool down for at least 30 minutes before plugging it back in and trying again.
Descaling Light: Time to Descale
The descaling light indicates that your Keurig needs to be cleaned to remove mineral buildup. Over time, minerals from the water can accumulate inside the machine, affecting its performance and potentially causing it to malfunction.
To descale your Keurig, follow these steps:
- Empty the water reservoir and remove the water filter.
- Pour in a descaling solution (Keurig sells its own, but you can also use a mixture of equal parts white vinegar and water).
- Fill the remainder of the reservoir with water.
- Place a large mug on the drip tray.
- Run a full brewing cycle without a K-Cup pod.
- Repeat the brewing cycle until the reservoir is empty.
- Rinse the reservoir thoroughly with water.
- Refill the reservoir with fresh water and run several brewing cycles to rinse the machine completely.
Descaling is an important maintenance task that should be performed regularly to keep your Keurig in good working order.
Dealing with More Complex Issues
If you’ve tried all the basic troubleshooting steps and your Keurig is still exhibiting a blinking light, the problem might be more complex. Internal component failures or electrical issues can sometimes cause blinking lights. In these cases, it is useful to determine whether the unit is still under warranty.
Power Cycling the Keurig
Sometimes, a simple power cycle can resolve minor glitches. Unplug the Keurig from the power outlet, wait for about 5 minutes, and then plug it back in. This can sometimes reset the machine and clear the error causing the blinking light.
Checking the Power Outlet
Make sure the power outlet you’re using is working correctly. Plug another appliance into the outlet to verify that it’s providing power. A faulty power outlet could be the reason your Keurig isn’t functioning properly.
Testing the Keurig with Filtered Water
Using filtered water can help prevent mineral buildup and improve the performance of your Keurig. Try using filtered water to see if it resolves the blinking light issue. This can rule out mineral deposits being the primary cause of the issue.
When to Seek Professional Help
If you’ve exhausted all the troubleshooting steps and your Keurig K35 is still displaying a blinking light, it might be time to seek professional help. A qualified appliance repair technician can diagnose and repair more complex issues that are beyond the scope of DIY fixes.
Identifying Potential Internal Problems
Internal component failures, such as a faulty heating element or a malfunctioning pump, can cause blinking lights. These types of problems usually require specialized tools and knowledge to diagnose and repair.
Considering the Cost of Repair vs. Replacement
Before you spend money on a professional repair, consider the age and condition of your Keurig. If it’s an older model or has experienced frequent problems, it might be more cost-effective to replace it with a new one. Weigh the cost of repair against the price of a new Keurig to make an informed decision. You can often find great deals on new Keurig machines, especially during sales and promotions.

Why is the small descale light on my Keurig K35 blinking?
The blinking descale light on your Keurig K35 indicates that the machine has detected a buildup of mineral deposits inside the water reservoir, brew lines, and other internal components. These mineral deposits, primarily calcium and lime, accumulate over time from the use of hard water. The machine is prompting you to run a descaling cycle to remove these deposits and ensure optimal performance.
Ignoring the descale light can lead to several problems. Mineral buildup can restrict water flow, resulting in weaker brews and longer brewing times. In severe cases, it can even damage the heating element or other critical parts, potentially shortening the lifespan of your Keurig K35. Addressing the issue promptly by descaling the machine will maintain its functionality and longevity.
What’s the difference between the descale light blinking and being solid?
A blinking descale light on your Keurig K35 generally indicates that the machine is reminding you to perform a descaling cycle. The machine has likely been keeping track of the number of brews or time since the last descaling and is now prompting you to run the cleaning process. It serves as a preventative measure to ensure optimal performance and prevent future issues.
A solid, non-blinking descale light usually signifies that the machine is in the middle of the descaling process. This often happens after you’ve started the descaling cycle, and the light will remain solid until the entire process is complete. If the light stays solid even after completing the descaling cycle, there might be an issue with the machine recognizing the process was finished, requiring a troubleshooting step like power cycling.
What is the best descaling solution to use in my Keurig K35?
The best descaling solution for your Keurig K35 is generally a commercially available descaling solution specifically formulated for coffee makers. These solutions are typically made with citric acid or other food-grade acids that effectively dissolve mineral buildup without damaging the internal components of the machine. Keurig offers its own descaling solution, which is often recommended for their machines.
Alternatively, you can use a mixture of white vinegar and water. A common ratio is 1 part white vinegar to 1 part water. While this is a more affordable option, it’s important to ensure thorough rinsing after descaling to remove any residual vinegar taste. Avoid using harsh chemicals like bleach or industrial cleaners, as these can damage your Keurig K35 and pose a health risk.
How do I reset the descale light on my Keurig K35 after descaling?
After completing the descaling cycle, the descale light should ideally turn off automatically. However, sometimes the light may persist even after running the full cycle. In this case, you can try power cycling the machine. Unplug your Keurig K35 from the power outlet, wait for a few minutes (around 5-10 minutes), and then plug it back in.
If power cycling doesn’t work, try running a plain water brew cycle. Fill the water reservoir with fresh water and run a brew cycle without inserting a K-Cup pod. This can help flush out any remaining descaling solution and potentially reset the sensor. If the light still remains on, consult your Keurig K35 user manual or contact Keurig customer support for further assistance, as there might be a deeper issue.
How often should I descale my Keurig K35?
The frequency of descaling your Keurig K35 depends largely on the hardness of your water. If you have hard water, which contains higher levels of minerals, you will need to descale more frequently than someone who uses soft water. As a general guideline, Keurig recommends descaling your K35 every 3 to 6 months.
Pay attention to the descale light. If it illuminates, it’s a clear indication that descaling is needed. You might also notice signs like slower brewing times, weaker coffee, or unusual noises during operation, which can be indicators of mineral buildup. Regularly descaling your Keurig K35 will ensure optimal performance and prolong the life of your machine.
What if the descale light is blinking but I just descaled it?
If the descale light is blinking immediately after you’ve completed a descaling cycle, the machine might not have registered that the process was finished. This could be due to a minor glitch or a sensor issue. First, ensure that you followed the descaling instructions completely and used the correct amount of descaling solution or vinegar mixture.
Try power cycling the Keurig K35 by unplugging it for several minutes and then plugging it back in. If the light persists, run a few cycles of plain water through the machine to ensure all descaling solution has been flushed out. If the light continues to blink, it’s possible there is a sensor malfunction, and contacting Keurig customer support would be the next best step.
Can I use bottled water in my Keurig K35 to prevent the descale light from coming on as often?
Yes, using bottled water, especially distilled or purified water, in your Keurig K35 can significantly reduce the frequency of the descale light appearing. These types of water typically have lower mineral content compared to tap water, which means less mineral buildup inside the machine over time. This will help keep your Keurig cleaner for longer periods.
While bottled water can help prevent scale buildup, it’s still important to periodically descale your Keurig K35, even if you’re using purified water. No water is completely mineral-free, and some residue can still accumulate over time. Following a regular descaling schedule, albeit less frequently than with tap water, will maintain the performance and longevity of your machine.
