I went to a café one hot afternoon for a drink when a stressed-out dude walked up to me. The Hamilton Beach Flexbrew single-serve in the cafe was not working. I guess he was the manager of the cafe. The coffee maker was acting up – sputtering, grinding, but wasn’t brewing.

I disassembled the coffee maker, tweaked some things, and put it back together. Then, with a dramatic flip of a switch, bam! It roared back to life. The guy’s face lit up like he’d won the caffeine lottery. So, if you’re facing problems with your Hamilton Beach Flexbrew single serve, read on. I’m here to help you fix it 

Hamilton Beach Flexbrew Single Serve Problems And Troubleshooting

Some of the common Hamilton Beach Flexbrew single-serve problems are the coffee maker not powering on, the coffee maker is not brewing, Hamilton Beach Flexbrew leaking, and not heating water. Let’s walk through each in detail and the troubleshooting steps.

Hamilton Beach Flexbrew Doesn’t Power On

You woke up to gulp down a hot coffee. Rushed to your coffee maker, and pressed the power button, but nothing happened. 

I know how you’re feeling right now because I’ve experienced this same issue.

If your Flexbrew isn’t turning on, it could be because the power cord is not properly connected to the electrical outlet or the outlet itself is bad.  It’s also possible that the circuit breaker has tripped or the fuse is blown.


  1. Make sure the coffee maker is plugged into a functional outlet. If you’re unsure about the outlet, try plugging in another device to be sure it’s working. 
  2. Examine the power cord for any visible damage or fraying. If you find damage, it’s time to replace the cord.
  3. If it remains unresponsive, you should look for any tripped breaker or blown fuse connected to that outlet.
  4. Reset the circuit breaker or replace the fuse if it’s blown.

      Coffee Maker Not Brewing 

      You insert a coffee pod, press the brew button, and expect a hot cup of coffee. Only to see a few drops trickle out, and the brewing process stops. I know how frustrating this can be, especially when you’re in a hurry to hit the road for work.

      This might be due to clogs in the water line, improper connection of the water reservoir, or the build-up of dirt in the coffee maker.


      1. Empty and clean the water reservoir thoroughly. Make sure it’s properly seated and well connected to the coffee maker.
      2. Check for clogs or obstructions in the water line. You can use a soft brush or pipe cleaner to clear any blockages.
      3. Regularly clean all removable parts, especially the water reservoir, drip tray, and coffee pod holder. For descaling, mix equal parts of vinegar and water and run a brew cycle without a coffee pod. Repeat this process until you can’t perceive the vinegar smell.
      4. If the issue persists, try using a different coffee pod or ground coffee.  The problem may be related to the coffee you’re using.

          Hamilton Beach Flexbrew Is Leaking

          After you start brewing, you notice water pooling around the base of the brewer, and it continues to drip even after the brewing process is complete.

          If you’re experiencing this, it could be that the water reservoir has some cracks or is loosely connected to the coffee maker. 


          1. Check if the water reservoir is correctly seated and properly attached to the coffee maker. Make sure it clicks into place.
          2. Inspect the water reservoir for visible damage. If you find any, you may need to replace it with a new one.
          3. Only fill the water reservoir up to its specified maximum capacity. Overfilling can make the water overflow during brewing

            Coffee Maker Not Heating Water

            One of the most common reasons for the Hamilton Beach Flexbrew not heating water is a problem with the power supply. It could be that it is not properly plugged in, or there might be an issue with the power outlet itself.

            Also, If the water reservoir is not filled to an adequate level, the coffee maker may not be able to heat the little water remaining.

            Over time, mineral deposits can accumulate in the heating element and affect it’s efficiency. This buildup can prevent the coffee maker from heating water properly. Some FlexBrew models allow you to select different brew sizes. Larger cup sizes may require more time to heat the water, so if you’ve chosen a large cup size, it might take a little longer for the water to heat.


            1. Make sure there is no issue with the power supply. Check the power outlet, cord, and circuit breaker. 
            2. Fill the water reservoir with a reasonable amount of water according to the desired brew size.
            3. Descale the coffee maker using a descaling solution or vinegar to remove mineral deposits.


              How Do I Reset The Clean Message On My Hamilton Beach Flexbrew Single Serve?

              When you use your Hamilton Beach coffee maker about 30 times, a ‘Clean’ message appears on the display. To reset this clean message, just unplug the coffee maker from the electrical outlet. Wait for a little while, then plug it back in.

              Why Is My Hamilton Beach Flexbrew Single Serve Not Pumping Water? 

              If your Hamilton Beach Flewbrew stops pumping water, it’s likely because it has some build-up of dirt. This build-up can clog the brewer and prevent water from flowing through to make coffee. To fix this,  run a descaling cycle to remove these blockages.


              By following the troubleshooting steps outlined in this guide, you can identify and resolve common problems with your  Hamilton Beach FlexBrew single-serve coffee maker on your own. If the issue persists, I recommend you contact a repair professional for help.
