Why Is the Keurig K-Express Descale Switch On?

All Keurig models have a descale light, including the K Express one. This light is a standard feature of Keurig coffee makers. It is an indicator that the coffee machine ought to be cleaned immediately when the light switches on.

Of course, it’s not without a reason why the light turns on automatically. You may not realize this, but the water you pour into the machine’s water reservoir actually contains lots of minerals that can accumulate inside the brew over time. When this occurs, the descale light will turn on, and the brew will stop running. And that’s your cue to descale your Keurig.

Reusable K-Cups packed too tightly may also cause the Keurig K-Express descale light to switch on. As a result, the water flow inside the appliance will be restricted, which might trigger the indicator light for descaling. Simply put, anything that blocks the water flow will turn on the descaling light.

  4. Continue Step 3 until the “Add Water” indicator light turns on.
  5. When it’s done, empty the water tank and refill with water until it reaches the max fill line. Hit the 8oz button to begin rinsing. Continue this step until the descale light switches off.

What If the Descale Notification Keeps Coming On?

If you have reset your Keurig K Express and turned the unit on again, but the descale light still switches on, there is something wrong. Below are a few common problems that make the descale light keeps switching on and how to deal with them.

1. Packed coffee pods

As previously mentioned, packed reusable coffee pods are one of the culprits that trigger the descale notification to turn on. To avoid this, try to not refill your coffee pods all the way up to the brim.

Also, do not press the coffee grounds just so you can make room for more. If you think the issue may have been caused by a densely packed coffee pod, make sure to remove the pod to see whether your Keurig allows you to perform a brew cycle without a pod.

2. Clogged exit and entrance needles

Another thing you can do on how to get descale light off Keurig K Express is by manually checking the exit and entrance needles. The exit needle is on the pod holder’s bottom part, while the entrance one is right under the brew handle.

Lift the handle and unplug the Keurig. The two small holes of the entrance needle should be visible here. To unclog these holes, consider using a needle or a safety pin. Do the same thing to the exit needle. But first, take off the pod holder and the funnel. The tube sticking out from the pod holder is the exit needle you should unclog.

3. Clogged tubes

Should all the above methods fail, there’s a chance your Keurig’s internal components have some dirt particles or air bubbles. You can lightly spank your unit to remove those particles. To do this, you will need to unplug your Keurig and take off the removable parts. These include the drip tray, water reservoir, filter, and coffee pods if there are any.

Bring your Keurig coffee maker to your kitchen sink and firmly slap it on the machine’s base and side. This method should be able to get rid of any potential particles that might have clogged the unit’s internals. Finally, run a few brew cycles with clear water to clear out anything blocking your unit’s water flow.

It’s essential to note that the water you pour into your Keurig is the main reason why you have to deal with the descale light that keeps coming on. As briefly mentioned above, the water you use may be classified as hard water that has a lot of dissolved minerals. These minerals will slowly build up inside your Keurig, and it will trigger the descale notification.

You can minimize the accumulation of minerals by utilizing a water filter system. Even so, you will still need to regularly descale your unit for at least three months. Otherwise, you will see the Keurig descale light stays on all the time.
