Fill the water reservoir and insert a K-Cup pod

A Keurig brews one cup at a time by forcing hot water through a small pod of ground coffee. To start, lift the handle on top of the machine — this opens the pod holder. Insert a K-Cup pod into the holder with the foil side facing down, then close the handle until you hear it click. The machine punctures the pod automatically when you brew.

Next, fill the water reservoir on the back or side of the machine (depending on your model) with fresh, cold water. Most reservoirs hold enough for multiple cups. You do not need to refill it every time if you are making several drinks in a row, but the water should stay fresh — if the machine has sat unused for a week or more, empty and refill the reservoir before brewing.

Key Takeaways

  • Insert a K-Cup pod into the holder, close the handle until it clicks, and fill the water reservoir with cold water before your first brew.
  • Select your cup size using the buttons on the front panel — most machines offer 6, 8, 10, or 12 ounces — then press the brew button to start.
  • The entire brew cycle takes two to three minutes from button press to finished cup.
  • Run a water-only brew cycle (called a rinse) every few months to clear mineral buildup inside the machine.
  • Empty the used K-Cup pod from the holder after each brew and discard it; the pod is not reusable.

Choose your cup size and press brew

On the front of the machine, you will see buttons labeled with cup sizes: typically 6 oz, 8 oz, 10 oz, and 12 oz. Press the button that matches the size of your mug or the strength you want. A smaller cup size means the same amount of water passes through less coffee, making it stronger; a larger size makes it weaker. If your machine has a "strong" button, pressing it before you select size will use hotter water and a longer brew time.

Once you have selected the size, press the large brew button (usually in the center or marked with a coffee cup icon). The machine will heat the water and begin brewing. You will hear water flowing through the pod. The entire process takes about two to three minutes. Leave your mug under the spout — the machine will stop automatically when the cup is full.

Remove and discard the used pod

After the brew cycle finishes, lift the handle on top of the machine again. The used K-Cup pod will be sitting in the holder, now punctured on both sides. Grab the pod and throw it in the trash — K-Cup pods are designed for single use and cannot be refilled by the machine. Some people refill them by hand with ground coffee and a reusable filter, but the standard way is to use a new pod each time.

If you are making another cup right away, you can insert a fresh pod and repeat the process without waiting. The machine stays hot between brews, so the second cup will brew faster than the first.

Descale the machine every three to six months

Over time, minerals from tap water build up inside the machine and slow down brewing or affect the taste of your coffee. Keurig machines have a descaling cycle that flushes these deposits out. You will need a commercial descaling solution made for coffee makers — Keurig sells its own brand, but any coffee maker descaler works.

To descale, empty the water reservoir and fill it with the descaling solution mixed with water according to the bottle instructions. Run the brew cycle without a pod in the holder, letting the solution flow into a mug. Repeat until the reservoir is empty. Then refill the reservoir with fresh water only and run the brew cycle three more times to rinse out any remaining solution. Your machine is now clean and ready to use.

Troubleshoot if the machine will not brew

If you press the brew button and nothing happens, first check that the water reservoir has water in it. The machine will not start a brew cycle if the tank is empty. Fill it and try again. If water is present but the machine still will not brew, the needle that punctures the pod may be clogged. Run a brew cycle without a pod in the holder to clear it — this is called a rinse cycle and takes about a minute.

If the machine brews very slowly or produces only a small amount of coffee, descaling is usually the answer. Mineral buildup narrows the passages water flows through. Follow the descaling steps above. If the machine still does not work after descaling and rinsing, check the user manual for your specific model, as some Keurig versions have slightly different buttons or reset procedures.

Clean the pod holder and water reservoir regularly

The pod holder — the part that holds the K-Cup — can collect coffee grounds and debris. Once a week or whenever you notice buildup, remove the holder by lifting the handle and pulling it straight out. Rinse it under running water and wipe it dry, then snap it back into place. The water reservoir can also be removed and rinsed if your model allows it; check your manual to see if yours is removable.

Do not put the pod holder or reservoir in the dishwasher unless your manual says it is safe to do so. Most Keurig parts are hand-wash only. Keeping these parts clean prevents mold growth and keeps your coffee tasting fresh.

Frequently Asked Questions

Can I use my own ground coffee instead of K-Cups?

Yes, if you buy a reusable K-Cup filter. These are metal or plastic pods with a fine mesh screen that you fill with ground coffee yourself. Fill it, insert it into the holder like a regular K-Cup, and brew as normal. Reusable filters cost between five and fifteen dollars and work with any Keurig machine.

Why is my coffee coming out cold?

The machine may not have had time to heat up. Keurig machines need a minute or two to reach brewing temperature when first turned on. If you just plugged it in, wait a few minutes before brewing. If it has been on for a while, try running a rinse cycle (brew without a pod) to heat the system, then brew your coffee.

How often should I replace the water filter?

If your machine has a charcoal filter inside the reservoir, replace it every two months or after brewing about sixty cups, whichever comes first. The filter removes chlorine and odors from tap water. You can buy replacement filters from Keurig or from most grocery stores in the coffee aisle.

What does the "strong" button do?

The strong button heats the water to a higher temperature and lets it flow through the coffee more slowly, extracting more flavor and caffeine. Use it if you like bold coffee or if your K-Cup is a mild roast. It adds about thirty seconds to the brew time.

Can I brew into a travel mug or tall glass?

Yes, as long as it fits under the spout. Most Keurig machines have a removable drip tray that you can take out to make room for taller containers. Check your manual to see if your model's drip tray is removable, or straightforward try placing your mug under the spout before you brew.
