Question about Keurig B100 Coffee Maker

1 Answer

B100 only dispensing 1tablespoon of water and drawer does not open

My B100 was only dispensing around 4oz of liquid and it was time to do the descaling. Following the manufacturer instructions I did the descaling process and did see lime deposits in the waste and rinse water but was still not getting any larger amount of liquid. Trying to improve the water flow I tried to descale a 2nd time. The machine now only dispenses a tablespoon of water and the drawer does not unlock for about five minutes after cycling.
Looking at the check-valve I found a little water on the wrong side of the valve and thought a lime deposit had gotten stuck so I soaked the valve in vinegar. I don't know how much air the pump is suppose to put out but it does put out a small amount, not enough to get through the check valve. I checked this by running a tube from the pump into a glass of water and saw bubbles. I connected the valve, put the valve in the water glass and did not see anything.
Is the check-valve suppose to open with air pressure from the pump or a suction from the other side?
Also, without the check-valve and pump connected the drawer does open after cycling.
Where can somebody get parts and/or service on these machines? I have put a second call into Keurig but have not yet received a response.
Thank you

Descaling with vinegar forget that you said after you decaled it it worst vinegar remove calcium in little chunks ckunks bloc everything use a special descaler it melt calcium just to prove you that im right you said you saw lime deposit if you use the descaler when the water come out no residue just water color change 1 part solution 1 part water put it in container start machine for few second stop leave it for 15 minute repeat untill empty that a hell of cleanup after dont forget to rinse that solution is very corosif cheers

Does not dispense enough water. I get about 2 ounces of coffee at a time. How do I adjust the water level?

When was the last time the unit was descaled? A build up of scale will gradually restrict and then stop the water flow.

Keurig b100

It sounds like one of two things happened when you disassembled the unit. Either the hose that controls the mechanism for the piercing arm (the part that puts the holes in the k-cup) became disconnected or pinched, causing the water to pour out over/around the k-cup. Or the k-cup holder is clogged or not seated correctly, which would cause the same problem. As for the little button you may have pushed, that can't cause the problem you're experiencing, so don't worry about that. Good luck, let me know if need more help. Erik

Drawer locks very little water comes out

in the water tank you have 2 sillicon tube one of them is stretch at maximum and usaly strech in 2. cut the part split and connect it again. the probleme is because the silicon left is propryety when is strech in very hot water. the best way to slove this problem is to find about 1 in of silicon tube of 1/4 or 3/16 iner and put the new parts of tube directly on the bafle and put the original tube in the new on. it just make a link betwen the bafle and the original tube. put teflon tape on the fitting of the bafle to avoid of the new tube spout out from the fitting.//// but take care and other touble can cause this the pump can be jam because the one way valve on the side of the brewer jam open because is to teith in in is body. check all is thing .if you need somthing eles y will comme back on the site soon :0)

Keurig B100 not pumping a cup of water through

After dismantling the B100 and trouble shooting the machine I determined that the hose leading to the air pump on the right side of the B100 allowed water to back flow into the motor. The small amount of moisture eventually caused the motor to fail.

I had to find a scrap machine, which most people that have bought this piece of equipment have just thrown it in the trash, and remove the motor from the opposite side which still functioned. Since it is designed to mount to a specific side I had to appoxy the motor into place. To keep the problem from occuring again I purchased a check valve from a local pet store and put it in-line with the motor.

This solved the problem at the source and has prevented moisture from getting into the motor. Now I am a proud owner of a Frankin Pot. It's alive!

Delivers only small amount of coffee per brewed cup

this is not a scale issue, mine arrived from the factory producing only 6oz of water. way to strong for most. called the factory, scale, scale blah blah blah, vinegar untill we were blue. bored one day took the unit apart. on the right hand side there is some clear tubing which housed a one way valve, took apart and the valve was partally clogged. removed cleaned and reinstalled, this valve works best when not fully" seated" where it belongs so reinstall gently into the hose and leave it alone. I know what your thinking scale, scale scale. wrong. still only made 6 oz cups. there is a timer device on the back wall of the front panel on the right side as you face the unit. it is adhered to the wall with two sided tape. pry it off and on the back low and behold is a timer screw that changes the length of pump run time. turn clockwise with a sharp knife or eyeglass screwdriver and retest. 9oz of water. shame on keurig for not being more responsive to its customers.
