SOURCE: Keurig B100 not pumping a cup of water through

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)

The pump is on the right side, has two wires coming out of it, and is connected to the check valve with a silicone hose. When you run a cycle, to brew a cup of coffee, that pump should be pumping air out, which pushes the hot water out of the tank.

So to test it, disconnect the hose and run a cycle to listen and feel for air coming from the pump. If it is not working (frozen due to the water permitted to enter from the failed check valve), you must remove it to dismantle the top part of the pump.

Getting the pump out is a little tricky... as you will see. There is only one philips head ***** holding it in, however, it is not easy to get to. I used a 90 degree angled *****driver, which worked well, after trying many other options.

Once you get it out, remove the three philips head *****s on the top of the pump right near where the hose was connected. Then separate the two sections of the pump. Inside there will be a fitting in the center that spins to actuate the pump. This fitting must be freely moving. If it is not, use WD-40 or a similar product to free the motor.

Clean up all the WD-40 from inside the chamber (so your coffee does not taste like oil) and reassemble. Then test it by running a cycle. The pump should now be working, if not repeat the process until the pump operates.

Since my last post, I have fixed another B100 that had the same issue. Keurig will not sell you a replacement pump or check valve, so you must repair that pump.

Good Luck, I hope this works for you. Erik

My shark vac and steam wont pump water to steam

Likely you have used tap water and there is now mineral deposits blocking the flow. I posted a video on how to take it apart to clean it.

ALternatively, people have had success in putting CLR into the tank or Vinegar and pumping the unit and leaving it overnight in attempt to clear the blockage that way. I gave up and just took it apart and found a significant amount of mineral deposits blocking things up.

My brand new h2o mop won't steam. Green light comes on and thats it.

bought it a few years ago - I used it a few times and it was fair but did leae a lot of water on the floors. My wife had wanted it as it was supposed to be a miracle device, but she had some health issues and not able to do heavy housework. She is better now and decided to try this miracle device she had wanted so bad - so we took it out and no steam - so this would be it's 3rd use and it's was dead. I'm a bit of a tinkerer so decided to take the thing apart/clean the nozzles etc per the troubleshooting guide. Well, none of the obvious/accessable nozzles were clogged, and the filter seemed to pass air and water ok (probably does have to be changed due to time vs uses. Anyway, took the unit apart and ended up having to take the pump motor apart - there is a little nozzle/connecter on the back of the motor that passes the water into the heating chamber. cleaned that with a pin - put it back together, and tons of steam shooting half way across the room. So - she did the floors, they are wet but clean. Bottom line - does an ok job but leaves a lot of water behind, and it appears the internal nozzles can be a problem, and not something the average householder would want or be capable of fixing. (they do say you can try using WD-40 in the unit to clear nozzles - not sure how it would get through to the pump nozzle, but maybe this would work ??
Anyway - may end up buying some more filters as we will want to get a few more uses out of this thing for our $100 bucks, but will stay away from them in the future (go back to the wet swiffer - does about the same job but much less cost and hassle).

Water comes out the accessory hose but not the floor cleaner

I had the same problem and the heater ports were clogged. I took apart the top unit and cleaned the ports with miniature bottle brushes used to clean spray painting equipment (purchased at Harbor Freight for $4). Reassembled and the unit worked fine.

My Bissell ProHeat 2x is pouring water out of the bottom anytime it's turned on. I had it in the shop for no water, took it back again for the same problem, took it back again because it had no suction,...

Took the unit apart and discovered my heater had small pinholes in the metal and they had put in silicone, instead of a gasket, which didn't seal. So much for the place I took it to "saving" my heater for me. I repaired it myself by getting a few o-rings and a seal from the hardware store. As for the "holes" in the bottom - a little marine fixative.

Hi my proheat bissell 7901 stopped pumping water to the floor, but it pumps water from the hand hose. I read the manual and followed how to check belt and the flat belt on right side of shampooer is fine...

just taken ours apart with the same problem... found it was caused by the 2 halves of the main casing coming apart in the area where the upright pedal release is. I found this to be due to the upper casing having broken in 2 places - the bottom of the screw wells. This means that the water tank cannot exert sufficient pressure on the valve to release the water. Only solution is a new top cover assembly

My B100 Keurig stopped pumping water

This is a very common problem, just call Keurig tech support. Explain the problem and they will send you a replacement unit and you get to keep you old partially functional unit. I bought mine in December 2009 and I'm on my 3rd unit already. They keep having the same pump issue and Keurig just keeps sending me replacement units. Their customer service is great, but I'm beginning to question their quality control.

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.
