Reason 2: Dirty Needles

If descaling doesn’t go for the goal of getting a full cup of coffee out of a keurig coffee machine, then sometimes problems could lie in the needle.

Because when we use K-cups then, their foil can stick up with the needles, and they can get dirty. Used needles can disturb pumping flow and can become a hurdle in providing a full cup of coffee.


Cleaning Process is pretty simple; all you have to do is to take a paper clip and adjust them in a needle, and then you can simple round them around but make sure that you don’t use any sort of tooth pics or things like them because they can be stuck in the needles, and that will make your problem even worst.

Reason 4: Blockage in Reservoir Tubes

Ever so often, the reason for not coming out a full cup of coffee could be a blockage in a reservoir tube. When something starts working between the reservoir and the tube, then water can disturb its flow, and the problem will make its way.


To get rid of such a problem, you have to clean the reservoir tubes. Rinse some water through the tubes and then pat dry them. Next, try to clean the area which connects the reservoirs with the machine through the tubes.

Use something that can increase the water pressure and then thoroughly clean the tubes and that area with the water.

After pouring and rinsing with the water, use some sort of blow dryer to blow out excessive dirt and debris that are left behind.
