How to solve a Keurig 2.0 Stuck on Preheating

Although your Keurig 2.0 takes only three minutes to go through the preheating stage, if it takes more than three minutes or is stuck in the preheating mode, this usually happens when there is a problem in your water tank, such as if it is not placed correctly in its place, or there may be some other reasons as well, like the water ports being blocked or a broken heating element.

In order to fix this issue, you need to clean the water tank and the water suction port, make sure that the white wire within the machine is not damaged, remove any clogs from the K-cup puncture needles, and then clean the coffee basket. For a temporary solution, you can try putting hot water in the tank.

Let’s go through this in greater depth below.

The Water Suction Port Is Stuck

Take out the water container from the Keurig coffee maker. At the back of your coffee maker, you’ll see a little white button, right beneath the location of the water container. This part of the machine sucks water.

Several times, push that white button to unstick it if it’s stuck. If the button is hard to push, it can be clogged with lime buildup. In this situation, put some vinegar on it and let it sit for about 30 minutes. After that, wash it with water and try to push the button again.

After all this, place the water container back in the coffee maker. This will make your machine sound more natural again.

The Water Tank Port Is Clogged

The exit points of the water tank can get clogged with hard mineral buildup.

Examine the water tank’s water exit outlet for any white scaling. If you come across any, use vinegar, water, or anything like a toothbrush to clean them.

Remember to thoroughly clean it afterwards, since vinegar may make your coffee taste bitter.

A Loose Wire Inside The Machine

Another reason for your Keurig 2.0 to be stuck on preheating is a loose wire in the machine.

Usually, the white wire gets loose, which can be found on the machine’s upper left side. If this wire becomes loose, your Keurig 2.0 will not preheat, and the screen will display ‘preheating’ forever.

Clean K-Cup Puncture Needless

Turn your Keurig coffee maker off and wait for about 2 hours. This helps cool any hot water contained within it.

Remove the machine’s top cover. There will be two silver needles pointing down.

To remove any obstructions from the first needle, insert a little plastic tube (similar to a straw) into it and suck. Do the same steps with the second needle. Blowing into the tube might cause the obstruction to go deeper into the machine, so don’t do it.

Turn your machine on when you have cleaned all the blockages from the machine.

After starting the machine, run it through some warm water to rinse it without inserting a coffee pod. Repeat numerous times to remove any residual clogs.

If you lack a straw, To get rid of obstructions, use a toothpick or a paperclip to probe within the needles. After that, run the machine through a few cycles of hot water to clean it.

Clean The Coffee Basket

If you’re still experiencing issues, the machine’s lower section might be blocked with coffee. To clean this component, first remove the Keurig machine’s top.

Locate the plastic component beneath the coffee dripper. It’s roughly the size of a little badminton birdie. Push it up gently to loosen and remove it. Be cautious not to injure yourself on the needles.

After removing this part, clean it well in the washbasin with a light detergent and water.

Put Hot Water In The Tank

If any of the above steps don’t work, you can attempt this temporary solution. 

  1. Unplug your Keurig machine and, if applicable, remove any K-cups.
  2. Heat 1-2 cups of water on the stove until nearly boiling.
  3. Carefully pour hot water into the water tank.
  4. Plug in your machine again. It will detect hot water and start the preheating process. This may assist in resolving the issue of the ongoing preheating cycle.

Making use of hot water can assist in accelerating the preheating process. However, keep in mind that this is simply a short-term remedy. If you use cold water, the machine will very certainly get stuck in preheating mode again.

To prevent future obstacles, you need to check and clean the water ports regularly. To make your machine work properly, you need to descale it every three months to remove the scale buildup.

After following all the above steps, your coffee maker should now be working properly. If the problem remains, then there may be another problem, like a broken part of the machine. In this situation, the best thing to do is contact Keurig’s customer service.
