Coffee makers how to fix the water pump

When the red exclamation point is flashing slow, something is not where it is supposed to be, bean hopper lid, door, brew mech, water tank empty, dregs box or water tray on dregs container is full. If the red exclamation point is flashing quickly, open the steam valve for pump priming. If pump turns on, and water passes correctly, the light should go off and return to heating stage. If not, we have a blockage or a pump that is not working correctly.

The Keurig machine operates by pumping air into the glass boiler to drive the hot water through your coffee cartridge. When you have put a new cartridge into the dispenser, you select a size of cup. When you press the go button, you should hear the machine pump water into the boiler to the requested cup size (test by selecting large size to hear the pumping work). Next the machine operates an air pump to force the specific amount of hot water through the cartridge and make the cup of coffee. The problem encountered with these machine is that a small amount of water can drip internally onto the air pump and it will either not operate or work intermittantly. There is a great 'how to fix' video on utube concerning the Keurig-taking apart and fixing.
Honestly, I don't know whether this is your problem, but I do know this happened to a machine I had. You should hear the tiny air pump working when the cup of coffee should be brewing. You can laboriously take apart and replace, and given the price of these units it may be practicle to do the repair. Watch video on utube--its like three or four parts and very instructive. Sorry I don't have the link.

Hi,
Below are solutions for a leaking coffee maker and how to decalcify the machine?
Tools and Materials needed to fix this problem are as:
* White Vinegar * Fresh Water * Volt-ohm Meter * Screwdriver
Step 1 - Clean
If your coffee maker seems to be clogged, try cleaning it with a mixture of white vinegar and water. Assuming that your coffee maker has a 12 cup capacity you will want to use 11 cups of vinegar and 1 cup of water. Fill the coffee pot to the 11 cup mark with vinegar and then fill it to the 12 cup mark with water.
Pour this mixture into the reservoir and turn on the coffee maker, allowing it to run through a brewing cycle as if you were making a pot of coffee. By doing this you will dissolve any build up in your coffee maker. If the coffee maker is leaking because the pump is clogged, then this might clear the clog and stop the leaking. If it has been a while since you last cleaned your coffee maker, you may need to run the vinegar through more than one cleaning cycle to dissolve all of the buildup.
Step 2 - Pump Valve
Unplug the coffee maker and examine the pump valve. If the pump valve is broken or has a clog, then the water will not be able to rise up and flow through the fill tube. When the coffee maker is turned on, the water needs to go someplace. If it cannot flow through the fill tube, then it may leak onto the countertop. If the pump in your coffee maker is sealed, you will need to replace the whole pump. If the pump is not sealed you should check it to ensure it is not clogged with coffee grounds or mineral deposits.
Step 3 - Brew Switch
Examine the brewing switch to ensure that is working. To get to the brewing switch, remove the base plate. Next, you will need to test the switch with your volt-ohm meter. Touch the tester to the RX1 scale. If it reads 0 ohms then you will know that the switch works fine. If it gives you a number other than 0 then it is time to replace the switch.
Step 4 - Tube Connectors
If the coffee maker is leaking or sputtering then you should take a look at the tube connectors. Many times, a leaky coffee maker is caused by faulty tube connectors. If you find the leak is in an elbow, clean the surfaces before you replace it. If the tube connector leaks, replace both the tube and the elbow so that you can be sure the pieces will both fit together properly.
To decalcify, you will be needing a : decalcifying cleaner and A container large enough to hold the same quantity of liquid as your water reservoir
1) Remove the machine's water reservoir. 2) Empty all liquid from the reservoir. 3) Fill the reservoir with warm water. 4) Add one packet of the recommended cleaner to the full reservoir and stir until the cleaner is dissolved. 5) Return the water reservoir to the machine. 6) Turn the machine on. 7) Set the large container underneath the steam wand. 8) Set up your machine so that hot water -NOT steam-will be emitted from the steam wand when the steam valve is opened. 9) Open the steam valve according to the manufacturer's instructions. 10) After all of the decalcifying solution has drained into the large container (within a few minutes this will occur), remove it and discard the liquid that has been collected. 11) Rinse the water reservoir thoroughly and then fill it with the type of water you usually use for brewing. 12) Return the water reservoir to its normal position. 13) Using only water repeat steps 7 through 9 until the water reservoir is empty again.
I hope the above helps....
Good luck.

Try this solution. It should fix your problem.

When was the last time you clean it with vinegar? Run vinegar through it and you will see hard water scales that were built on the heater. Coffee makers should be clean out every month then with 2 rinse cycles after that.

you have "Hard water residue". built up in the pump, try using 80/20 Vinigar, to water and keep letting it set/then run it through, even if it takes a while, just don't let it get "burned up, this should fix your problem, also you could try CLR in the Green Bottle, JUST MAKE SURE YOU READ THE DIRECTIONS AS TO COFFEE MAKERS, and hard water deposits,god bless

I fixed the problem. Just send me $9.95 and I'll tell you how I did it. This is my Premium Plan!
Thanks,

go into the menu and reduce the amount of water the machine pumps through

thanks
