Partial Brewing Keurig 2.0

The water is only dispensing a couple drips at a time.


The problem Rosie describes with her brewer is known as partial cup brewing; a very common fault with the older classic machines like our B60 unit. However for the newer 2.0 series of brewers it’s not a fault we hear much about …. yet.

What use to sometimes work with the classic machines is the “Keurig Burp”. This applies a small jolt to the air pump, which is the usual cause of partial cups of coffee. We have a couple of guides that might be of help in this case. The first is trying the burp approach, and this can be found here. The second looks into the causes of partial cup brewing in more detail and that can be accessed here.

The purpose of the air pump in these brewers is to build the correct air pressure inside the boiler unit that is then used to force the heated water out, across the top assembly, through the entry needle and into the waiting K Cup. When the air pump becomes damaged or just breaks down, the brewer is unable to build the air pressure and so the water, or only a little, makes it to the K Cup … which of course means then not much makes it into your coffee cup. The most common cause of air pump failures in the classic brewer was corrosion through moisture damage inside the machine (most often coming from solenoid leaks).

What we recommend for Rosie is she ask Keurig to send her a new brewer as a replacement. Under the one year warranty this type of fault is very much covered. We recommend this, rather than any repair, as this first off invalidates the warranty and second one might as well have a new brewer than to have the old one breakdown later … when out of warranty and Keurig will not be that interested in helping.

Keurig’s customer support team can be contacted, toll-free, on: 1-800-361-5628 (for Canadian residents). For those in the USA their number is: 866‑901‑BREW (866‑901‑2739).

All that you will need is the brewer’s serial number, which we have a short guide to help with too.
