Before You Start

Before you begin the priming process, there are a couple of quick tricks to try. You may have a Keurig prime error and not need to go through the whole process. If you see the PRIME message, you may have incorrectly attached your water reservoir, or your Keurig may simply need to be reset.

Try detaching and reattaching your water reservoir (if it’s removable). Make sure everything is lined up and looks right. If that doesn’t help, try unplugging your machine and letting it sit for a few minutes. Then plug it in, turn it on, and see if the prime message has disappeared.

Why does your Keurig say prime?

The prime message on a Keurig typically means that minerals have built up in the tanks and tubes. Minerals in your water, like calcium and limestone, can stay behind and get in the way of your coffee maker’s water flow. That’s why you need to clean and descale your Keurig regularly.

If you can remove your water reservoir, take it off and wash it thoroughly with soap, a soft sponge or washcloth, and warm water. If you can’t remove it, place your machine in the sink and wash it carefully, making sure not to get any other parts of the machine wet.


3. Clean the needle.

You don’t want to taste cleaning supplies in your next cup of coffee, so you’ll want to rinse your Keurig out. Do this by filling your water tank with plain water and running brew cycles until it’s empty.
