How To Descale a Keurig That Keeps Shutting Off

Keurig Troubleshooting Dec 24, 2023 No Comments

You keep hearing that to start a Keurig coffee machine that won’t work, you have to descale it.

But the question remains, how do you successfully descale a Keurig machine that keeps shutting off at the start or middle of the descaling cycle?

In this post, we will work on what is causing your Keurig to shut off first. Then, once you get your coffee machine up and running, you can start the descaling process and complete it without an issue.

An Air Bubble Is Causing Your Keurig To Shut Off

The most common reason for a Keurig to shut off before it can start descaling is an air bubble blocking the water pipes inside the machine.

This issue happens more often with Keurig machines that have been stored away for a long time. Or if you leave the water reservoir empty for a while.

Descaling requires constant water flow running throughout the coffee machine. If an air bubble traps the flow of the water, it will shut off immediately.

How To Get Air Out of a Keurig

There are several methods you can try to get rid of an air bubble inside a Keurig. Even though some will sound a bit weird to you, please give them a try!

Turn the Keurig upside down and shake it

Remove the water reservoir from the Keurig and set it aside. Take the machine over the sink, turn it upside down, and give it a good shake.

While this might sound silly, most of the time, it’s the winning method. Many users will see a bit of gunk fall out, or water dripping out of the reservoir intake, which could have been the culprit all along.

After a good shake, you can now put the reservoir back in its place, fill it up at least halfway, and start your machine.

Prime the water reservoir

This is another simple yet effective method of getting air out of a Keurig.

Fill the water reservoir with a quarter water volume only. Now, lift the reservoir up and down quickly. You want to take it out and then insert it back into the water valve in a rapid motion, which will cause air bubbles to come out of the valve.

Repeat this until the air bubbles stop forming inside the water tank. This will indicate that the water has finally made it fully into the internal tank and the blockage has been removed.

Blow air through the water intake

You can help push out the air bubble with the help of a straw or a turkey baster, whichever is more convenient for you.

Remove the water reservoir. You’ll want to place a straw inside the intake where the reservoir attaches to the machine and blow air through it. Or you can use the turkey baster, alternatively. You’ll need to repeat this process several times and then give your Keurig a try.

While you are at it, turn the reservoir upside down and make sure that the valve underneath is clean and is not clogged with limescale or gunk.

How To Test Your Keurig Can Descale Again

If you tried one or more of the methods above to get air out of a Keurig machine, here’s how you can test that you have fixed it.

To test if the machine is now running correctly, brew an empty cycle. Without inserting a pod, press on any serving size to dispense hot water. If you get the full amount without the machine stopping, the issue is now fixed!

Your Keurig is now ready to run a full cleaning and descaling cycle without stopping.
