Keurig Clogged With Coffee Grounds

There are two common causes of your machine becoming clogged, one is with coffee grounds and the other a build up of mineral deposits, calcium build up or limescale.


both are easy to fix and much in the same way.

The best and the easiest way to tell if it is coffee grounds that are causing the blockage is by examining your cup of coffee for coffee grounds making their way into your cup of coffee.

If your machine is blocked, and you have no coffee grounds in your cup of coffee, the cause of the blockage is likely a build of minerals, calcium or limescale.

How To Fix A Keurig Clogged With Coffee Grounds

This is where you start unclogging your needling and directly clearing your needles.

Start by locating both the exit needle and the entrance needle by opening the brew head.

The exit needle is found below the K cup holder, the pod holder.

Remove the pod holder and clean it with soap and water and rinse well.

The entrance needle, also known as the puncture needle, is located on the upper part of your brew head and directly above the pod holder.

Practice caution when you are near or around the needles as they are both very sharp.

Step 1: Run A Hot Water Brew Cycle

Start by cleaning your water reservoir and the water filter with soap and water and rise well.

Then fill your water reservoir with fresh water only. Run a full brew cycle until your water reservoir is empty.

Repeat this step for a second time, refilling with clean water and running a second brew cycle until it is empty.

This is a nice easy way of getting all the easy loose coffee grounds and particles free.

Step 2: Clean Your Needles

Unclog your needles by poking around inside both of them with an unfolded paper clip, a pipe cleaner or a long thin needle.

Spend at least one minute poking around inside each of the two needles and paying attention to loosen hard, stuck debris.

Step 3: Run A Quick Flush

At this point you have cleared significant blockages in your needles and the immediate area leading up to it, but as you can imagine a lot of the coffee particles have fallen and become stuck inside your coffee machine.

Fill your water reservoir with fresh water and run a hot brew cycle until it is empty. Repeat this step to ensure all the coffee particles have been cleared.

Step 4: Using Your Needle Cleaning Tool

Locate your Keurig needle cleaning tool, if you have lost it you can order a new one from Amazon, eBay, and of course Keurig.

Fill your orange needle maintenance tool with 50% cleaning vinegar and 50% fresh water.

Open and close your brew head 5 to 7 times; this has a pumping action and helps to clean your needles of coffee oils and other dirt and grime.

Repeat this step to ensure your needles are fully sanitized.

At this point your needles should be fully clear of any blockages. Now run a full and complete descaling cycle using a solution of equal parts cleaning vinegar and clean water to ensure that your coffee maker is clean.

Then run a second descale cycle for good measure. Finish by flushing out your machine with 5 to 7 fresh water-only cleaning cycles. This will rinse out your coffee maker of all scents and traces of vinegar.

Keurig Clogged After Descaling

If your Keurig coffee maker is still clogged after running a full and proper cleaning of your needles and a complete deep clean and descaling cycle it is best that you contact customer service as there may be something deeper wrong with the internal workings of your machine.

It may be there is something wrong with your water pump.

After this initial cleaning cycle run a light clean every 15 days with 25% vinegar and 75% water. This is to maintain your machine in prime condition for coffee brewing.

Once per month run a full descale with equal parts vinegar and water. One cleaning cycle will be enough as you will have maintained your machine in great condition.

Get into the habit of pre-filtering your water by using a water filter jug. This is essential to preventing the build up of limescale and mineral deposits even if your coffee maker has a built-in water filter.
