Keurig 2.0 Stuck On Preheating Mode (Solved!)

Struggling with your Keurig 2.0 stuck on preheating? Don’t worry! This guide is here to help you tackle this common issue.

While a Keurig 2.0 should typically preheat within 3 minutes when the water tank is properly seated, complications can sometimes arise.

I’ll walk you through the troubleshooting steps to get your coffee machine brewing in no time.

How To Fix A Keurig 2.0 That Is Stuck On Preheating?

If your Keurig 2.0 is stuck on preheating, it’s usually due to issues with the water tank, such as it not being seated properly or clogged water ports.

To fix this, clean the water suction port and the water tank port, ensure the white wire inside the machine is not loose, clear the K-cup puncture needles of any blockages, and clean the coffee basket. As a temporary fix, you could try using hot water in the tank.

Let’s get into some more detail below.

Keurig 2.0 stuck on pre-heating

The Water Suction Port Is Stuck

Take off the water container from your Keurig coffee machine. Look for a small white ‘button’ at the back of the machine, right under the place where the water container usually is. This is the part of the machine that sucks in water.

Try pushing this white button a few times, to free it if it’s stuck. If pushing the button is very hard, it could be blocked with limescale. In that case, pour some vinegar into it and leave it for around 30 minutes, then clean it out with water and push the button again.

After that, put the water container back onto the machine. If your machine was stuck and not making its normal sound during pre-heating, this might make it start to sound normal again.

The Water Tank Port Is Clogged

Just like the water-sucking port in the machine, the water exit port of the water container can also get blocked with hard mineral deposits.

Check the water exit port of the water container for any white scale. If you see some, clean it using vinegar, water, and something like a toothbrush.

Don’t forget to rinse it well afterward because vinegar can make your coffee taste like @ss.

A Loose Wire Inside The Machine

Another thing that can cause your Keurig 2.0 to be stuck in preheating, is a loose wire on the inside of the machine.

It’s common for the white wire, which is located on the top left side of the machine, to come loose. If this wire is loose, your Keurig 2.0 won’t preheat and the screen will keep showing ‘preheating’ indefinitely.

Clean The K-Cup Puncture Needles

Turn off your Keurig machine and wait for at least two hours. This is to cool down any hot water inside it.

Open the top part of the machine. You will see two silver needles pointing down.

Use a small plastic tube (like a straw), put it on a needle, and suck, to remove any blockages from the first needle. Do the same with the second needle. Don’t blow into the tube as it can push the blockage deeper inside the machine.

Only turn on the Keurig machine when you are sure you’ve cleared any blockages.

After turning on the machine, run it without a coffee pod to rinse it with just hot water. Do this several times to clean out any remaining blockages.

If you don’t have a straw, you can use a toothpick or paperclip to poke inside the needles and remove blockages. Afterward, run the machine with hot water a few times to clean it.

Clean The Coffee Basket

If you’re still having issues, the lower part of the machine might be clogged with coffee. To clean this part, first, open the top of the Keurig machine.

Locate the plastic piece underneath where the coffee usually drips out. It’s about the size of a small birdie used in badminton. Carefully push it upwards to loosen and remove it. Be careful not to hurt yourself on the needles.

Once you have removed this part, clean it well in your sink with some mild detergent and water.

Put Hot Water In The Tank

If everything above didn’t work you could try this temporary fix.

  1. Unplug your Keurig machine and remove any K-cup if present.
  2. Heat 1-2 cups of water until it’s almost boiling.
  3. Open the water tank and carefully pour in the hot water.
  4. Plug your Keurig back in. It should detect the hot water and begin the preheating process, which can help resolve the endless preheating cycle issue.

Using hot water can help jump-start the preheating process, but remember, this is just a short-term solution. If you go back to using cold water, the machine may likely get stuck in preheating mode again.

Final Steps

If the blockage was caused by mineral buildup, you should run a cleaning cycle with a descaling solution after you’ve cleared the machine. This helps to remove any leftover buildup inside the system.

Always be careful when you’re using your Keurig machine, especially when dealing with hot water or sharp parts like the needles.

To avoid future blockages, regularly check and clean the water ports. Removing mineral buildup every three months by running a descaling cycle can help keep your machine working well.

Once you’ve done all these steps, your Keurig should be working fine. If it’s still not working, the problem might be bigger, like another broken part inside the machine. In that case, the best thing to do is reach out to Keurig’s customer service.
