Noises coming from a Keurig coffee machine are nothing to be concerned about. Most of the time, these sounds are caused by a simple issue that you can fix yourself.
In its normal state, a Keurig coffee maker will make some sounds while it brews coffee. But if you feel like your Keurig sounds out of the ordinary, or it won’t brew as usual, refer to the guide below.
What Does The Noise Sound Like?
Here are some of the common noises that come out of a Keurig machine to help you identify the issue:
|Water heating or decompressing
If you are not sure what the noise you hear coming from the Keurig machine sounds like, keep reading for an explanation of each issue.
Gurgling or clicking noises when drawing water
A Keurig coffee maker will make a gurgling sound when it is heating water. It gets louder when drawing water because it is heating water to make the coffee. Think of this sound as a kettle gurgling while it boils.
A clicking or a grinding noise when drawing water, or if it’s not pumping water at all, means that you have a clogged pipe. This is a clear indication that it is time to descale your Keurig brewer.
Tips for avoiding this issue
- Always use filtered water. When using tap water, make sure to use a water filter inside your Keurig.
- Descale your coffee maker regularly. Avoid using a mixture of water and vinegar and use a descaling solution instead. Vinegar is acidic, but it’s not strong enough to clear out all the build-up inside the machine.
Noise that comes while a Keurig is turned off or after brewing
Some Keurig models will make what many users refer to as buzzing, humming, or popping sounds after brewing, or sometimes even when the brewer is unplugged. There are two reasons for this:
Decompression and Purging
Some Keurig models are designed to decompress to bring themselves back to normal temperature after brewing. This would result in the clicking or popping sound you hear. It is not coming from the machine itself, but rather from the plastic housing of the machine.
Sometimes, after a brew or two, the air gets trapped in the lines inside the machine. This is another reason for weird sounds coming from inside your machine.
None of these noises are something you need to fix. These are not issues that affect the performance of your Keurig. But if you want to avoid them, you can try these two methods:
- You can push out any trapped air by running an empty pod cycle. Without inserting a pod, hit the brew button to dispense hot water. You can do this once or twice to keep water running through the pipes.
- Another thing to try, especially if the noises are happening after brewing, is to open the lid of the reservoir and keep it that way until the machine cools. Chances are, the noises are coming from air in the internal reservoir looking for an escape. This happens especially in models that don’t have an external water tank, such as the K-Mini.
The coffee maker will not brew and keeps clicking
A clogged puncturing needle causes a clicking sound when you hit the brew button and no coffee comes out. Or times, you’ll notice a slow brew or half a cup only.
The clicking noise comes from the machine trying to pump water through the coffee pod, but it’s not going through due to clogging inside the needle.
This is easily solved by cleaning the puncturing needle using a paper clip.
Unfold the paper clip and use it to unclog the needle placed in the machine lid. Push the paper clip into the needle to get rid of any dry coffee grounds causing the clogging.
When you’re done, run an empty brew cycle without inserting a cup (only hot water comes out) to get rid of any residue. If the water comes out perfectly, then your needle is no longer clogged and you should be able to brew coffee again.
The brewer won’t turn on but makes a clicking sound
If your Keurig is making a clicking noise and won’t turn on, or it turns on and then off again, it means that it’s trying to run power through but something is stopping it.
The first thing you’ll want to do is to make sure that the outlet you are using isn’t causing the issue.
Try switching to another outlet and see if the coffee maker runs correctly. If it still won’t turn on, then it confirms an issue within the Keurig brewer.
The clicking sound is most likely coming from a corrupt capacitor and the power not being able to circulate. If your machine is still under warranty, I would advise you to send it for repair. If it’s an old Keurig, then it might be time for a new one.
