Loud drilling noise when coffee switch is turned on - rather than the usual purring noise - and no coffee delivery either

How old is your machine ? and what maintenance have you done over time such as replacing the shower curtain located at the pourring end of the hot water ? I had too very loud noise coming occasionnally from the stainless steel rack holding the cup while coffee is delivered. If your ground coffee is too fine it will stop flow during making a shot. Is water coming out when no coffee is placed in the portafilter.The water pump on this machine is a cheap pump that has to be replaced over time. Mine is 7 years old and has delivered four cups of expresso everyday of the year, and still working.3841c994-fb4b-459f-8d1f-710e0aafc3c0.jpg 2ead4f70-37c6-4236-a9c2-992dba149c4c.jpg

Water builds up on top of k cup and leaks all over the k cup

I had several issues. Initially it would heat up and flash indicating it was ready to brew, but it wouldn't produce any water. It would hum for a while then eventually stop. So, first I used a paper clip to make sure the three holes around the needle that pierces the top of the k-cup were clean.You can also easily remove the k-cup holder and clean the hole for the pin that pierces the bottom of the k-cup. For some people this seems to be enough. That didn't work for me, so next I took the top off to expose the pump tubing (pull top handle all the way back and remove two screws under the top--the screws are a bit hard to get in later, try taping screw to screwdriver so you don't lose screw). I noticed the internal water tank was full almost to the top, so I knew it was not at this point an issue with the external water tank. Apparently when the pump dries out it sometimes can't prime itself, or crud gets in the line. One person said they used a turkey baster to force water up the needle (without needing to remove the top). I'm not sure why that worked, because the pump valve seems to be one way--I couldn't blow air in to it (see below). Anyway, I don't have a turkey baster, so I unscrewed two screws to get at the pump line, and then wedged up the black ring that holds the pump line down to the place of output. I ran the brewer and noticed no water come into the line, so I sucked on it a little bit (like siphoning gas). All of a sudden some very hot plastic-tasting water came through. (Not scalding fortunately.) I ran the brewer again and this time water came out (I just held the now-disconnected line over a coffee cup). I ran it again and this time it was trying to refill itself but no water was entering the brewer. Fortunately, I came across this solution. I re-attached the pump. Then I took off the external tank and Iused a screw driver to push up from the bottom of the valve (underneath where it flows into machine) and saw that water came out freely so I knew there was not blockage there. Next I tried the slam down technique described above. That worked like a charm--the tank started draining and I finally got everything working.

Keurig B70 automatically pumps water when turned on

When you purged the lines or tubes retained debris and need full purging and flushing.

I suggest you use vinegar acid.

You need a solution with half part water and half part vinegar acid.

1) pour 4 cups of water into your coffee machines water tank.

2) pour 4 cups of vinegar acid into your coffee machines water tank.

3) turn on your coffee machine to decalc.

4) refill tank with clean cold water and let it run through ( 2 times)

If you pour water into acid it can explode and make terrible damages and cause chemical burns!!!

Hope this will help ypu

Keurig B60. Brand New used maybe 4 Kcups. Now it won't fill a full cup setting. Maybe 1/4 cup. You reset, get a little more to run through. At this rate going to be a long time for a full cup. took...

if water does go thru it...try white vinagar/water mixture about 1/2 cup vinagar to full tank water..
run cycles until empty...NO Kcups..then run full tank of clean water.....

The coffee maker will not work. It keeps saying

As others have said...just keep reseating the water tank, 20-30 times may be necessary. You will see air bubble come up and until you stop seeing bubbles, keep dropping the tank into place. Eventually it will start to **** water from the tank filling the brewer with about 20oz of water. Wait a couple minutes for the water to heat and it will indicate ready and just select brew cup size. This will work. We just had the same problem today with our first breville coffee brewer and now it works great.
