Question about Keurig B100 Coffee Maker

1 Answer

It seems like the part that contains the sharp needles in the chamber cup provided with the coffee maker has "disappeared" making the coffee grounds go through the hole at the bottom leaving grounds. Can this part be replaced and where do you suggest I obtain one?

Cuisinart coffee center, ss-15, lights are flashing on cup sizes, and won't make single cup coffee.what to do?

We have the Cuisinart combination 12 cup coffee maker with a 6,8,10 K-cup maker. Today 8/06/2017 the K-cup started making a strange sound stopped working and all 3 blue lights 6,8,10 where flashing and wouldn't make a cup of coffee. After some looking around it seemed that the top stainless steel water injector was clogged, I took a long toothpick and slowly pushed it in as I spun the toothpick around slowly as to not break the toothpick off inside, the water injector is sharp so the toothpick will fray as you spin it around inside this is why you must go very slowly. I also did the same to the K-cup holder stainless steel spike tube to make sure everything was clear and clean, I then ran 4 full water containers through the K-cup system starting with the 6, than 8 and 10 oz. size. I was finding little black objects in my 20oz drinking cup as I was doing this, not sure what that was but after running the 4 full containers through it they were gone. Now it works fine. I hope this helps anyone with the same machine having the same problem

Coffee grounds in the coffee

There are a couple things that could cause that, that I experienced:
1. I found that the water injection needle sometimes gets dirty. Coffee grounds are in it and cause the water to go over the top and wash coffee past the k-cup into your coffee cup.
You can use a paperclip to clean out the needle.

2. There is a whole in the k-cup somewhere or the lid is not properly / or strongly enough glued to the k-cup. The water-pressure then pushes coffee out of those holes around the k-cup into the coffee mug.

3. The plastic insert where you put the k-cup in is dirty itself (I have to clean it every now and then).

4. The coffee in the k-cup is ground so fine that it gets pushed through the whole on the bottom that is being punshed for the water to escape.

You need to purge the system. Clean the upper needle port with a paperclip end. Stick it all the way up the tube and into the reservoir. That will allow water and air to push out from the chamber. Make certain the Water Filter is changed. Blow out the tube from the lower water container with Canned Air. Always use Distilled or Filter water as city water has too many minetrals that collect inside of the heating chamber.

We are getting coffee grounds in the brewed cup of coffee. How do I fix this?

Keurig b31 brewer is not bewing 2 week old machine

Important discovery I wanted to share.

My B31 Kuerig worked great for over a year, then suddenly seemed unable to spit out any coffee or even water when no coffee pack was loaded. Descaling did nothing to fix ... only a drop or two of water (or vinegar) could flow out the machine.

I was able to fix it by clearing grounds stuck in the holes of the TOP needle, NOT the needle opening in the funnel for the bottom of the cups.

The instruction manual for the B31 does not tell you to clean the top needle ... it just says how to clean the funnel and the bottom (exit) needle ... but the Kuerig video on YouTube does explain where to find the top needle and how to clear it of a jam from corrosion or coffee grounds.

Be careful ... the top needle is sharp, and it is hard to spot the tiny slots in it.

Using a paperclip, I was able to push up and clear some grounds that were blacking water from flowing freely. These grounds then came out with my next cycle of water.

To see the upper needle, look up into the top of the machine after you open it. There are also two screws you can take out to see the top tube of water flow down to the coffee cup. That is where I was able to spot some grounds that came lose after I used a paperclip to clear.

I was ready to trash my machine ... now it is good as new. Good luck!

When making a cup of coffee, half the water flows back thru the vent resulting in half a cup of coffee. I have de-scaled but that did not fix. Any suggestions?

When the water comes back through the vent, it usually means that the TOP needle may be plugged with coffee grounds.

Unplug the coffee maker.

Lift up on the silver handle, and look inside. You will see a silver needle (similar to the one in the bottom of the K-cup holder). With a round seal surrounding it.

Straighten out a paper clip and run the clip through the center of the needle, and rotate it, then pull the clip out.

Plug the unit back in, and wait until it is ready.

Remove the K-cup holder, and run only water through the unit, as if you are making a cup of coffee.

You will see some grounds in the coffee cup, if the needle was plugged with grounds.

If this doesn't fix it, call customer service, the unit may be bad.

When I brew a cup of coffee there are coffee grounds in the coffee?

Take your K-cup out and it splits into two pieces. The buttom half has a chamber where coffee grounds that slip out can sit. When it builds up you tend to see allot of grounds in your coffee.

Also check that your top needle seat is there and in good condition.

Barely any coffee rises to upper chamber after cooking

It's the gasket!!!!! Store the pot with the two parts screwed TIGHTLY together for about a week. Tighten it up as the new gasket compresses. Problem solved in two weeks or less. Also cook on medium to low heat. High flame seems to make the problem worse.

Coffee ground are coming out of the k-cup area

Make sure the needle in the bottom of the K cup holder is not missing, broken or bent. Also, look at your used K cup when it comes out. Is there a hole in the top and the bottom? It sounds like the pressure is building up within the K cup due to a backup at the bottom of it. This could also occur if the bottom needle hole is obstructed. Be careful...the needles are sharp!

Can only make a cup of water without single serving in.

I had similar results and figured that the outflow needle, which punctures the bottom of the cup, might be clogged. The outflow needle can be accessed by just opening the top and removing any existing K-cups. I slid a narrow, stiff wire into the needle, and reamed it out a little bit. The coffee maker now seems to work as well as ever.
