TRY 1. Lift up the water reservoir and drop it back into place. There is a magnet that has to be in the right position and putting the reservoir back into place causes it to go back where it should be. This method has worked for me.

or 2. It may be time to descale. Most models will give you a message when it's time to have the mineral deposits cleaned.
HERES HOW TO DO THAT...
Empty water resevoir. Disable auto off. Pour approx 48 oz of undiluted white vinegar into resevoir. PLace large mug on drip plate, run brew cycle, dump contents of mug in sink. DO NOT USE A K-CUP.
Repeat this process until the add water light is indicated.
Let brewer stand for at least 4 hours while still on.
Discard any residual vinegar in the resevoir and rinse thorughly.
AFTER approx 4 hours...fill resevoir with water.
RINSE:
PLace a large mug on the drip plate and water brew cycle. Pour the contents of the mug into the sink.
REPEAT this brew process until the add water light is indicated.
YOU MAY NEED TO REPEAT THIS "RINSE" PROCESS if you notice any residual taste

Sorry to read about your issue.

The brewer should be de-scaled at least every 3-6 months. Scale is harmless, but if left unattended, it can hinder optimal brewer performance. De-scaling your brewer regularly helps maintain the heating element, removable water reservoir and other parts of the brewer that come in contact with water. Better water quality and water heating means a better cup of coffee, tea, hot cocoa or iced beverage. We recommend de-scaling your brewer at least every 6 months (every 3 months if your water has a high mineral content). The de-scaling process involves using 48 ounces of undiluted white vinegar.

Take 48 oz of white vinegar. place in tank. pretend you are making coffee (Do No Use K Cup). let the water fill you mug. then empty that mug. Do it again until tank is empty. then let sit for 4 hours.
Then fill with fresh water to the top. let that tank of water run thru. towards the end taste the water.
If you taste vinegar..use more clean water, until the taste is ok.

I tried to help you. Please help me and Vote/Rate this response. Thanks and good luck

How to reset keurig b40


1. There is some confusion over models. I've seen "B40" models and instructions with only one size cup button, both labeled B40. I own one stamped "B40" on the bottom, and it has two buttons -- small and large. FWIW, small = 8 oz, large = 10 oz.

2. These reset instructions from another site seemed to do something
What to Do If Your Keurig Won Brew Cup Barista

So.. this is what I did that worked for mine: 1) Hold down Auto-Off and LARGE cup at same time. (all lights should hold steady ON) 2) press SMALL cup while still holding Auto-Off and LARGE cup 3) Release all three, press LARGE cup again.. all lights should go off. 4) Unplug for about 5 - 10 second, plug back in. SHOULD WORK!

3. On *_my_* B40, remove the K-cup, close the door, fill the reservoir. Unplug and replug the B40. All lights should be off.

Pressing "Auto Off" and "Large Cup" together will turn on 3 lights (Heating, Add Water, Power) for about 3 seconds. Doesn't matter how long the buttons are pressed or what order they are released.

I tried lots of add-on combinations: e.g. press button x, press x multiple times, press x while lights are still on, press x after lights are off, press buttons x and y together, press x then y, press x and/or y while still holding Auto and Large, release Auto but not Large and press x, etc.

Nothing gave any confirmation that a reset was accepted. All lights always turned off after 3 seconds. Maybe Reset is only 1 step, i.e. Auto+Large together?

My Keurig Brewer is flashing the add water, heating and small cup brew lights. The water reservoir is full and I have taken it off and placed it back on. If I press the small brew button it acts like it...


Perhaps more than one problem people are dealing with but here's what I found. The round float in the tank is magnetic so it's either activating some crappy mechanical switch or more likely a hall effect sensor. Remove the tank and dump the water so the float will rise from the bottom when you refill it. Take a good strong magnet and slide it around the side of the unit where the float would be, tapping it as you go. Put the tank back on and fill it. One try and I was back to making coffee.

No water coming out makes noise and slite water and its not hot


Use vinegar as water and soak over night. Use the same vinegar as water the next day as if brewing coffee. Then use fresh vinegar as if brewing coffee. Next use water several times until you don't smell the vinegar. Now try brewing a pot of coffee. good luck.

Keurig B60 coffeemaker stopped pumping water because I didn't notice there was almost no water left in the chamber and started it--I added water right away but it won't pump any more water out of the...


This morning my Keurig sounds like it begins to pull water then stops. I tried to cut it off then back on. Still didn't work.Removed water from reservoir and K-cup and added pure vinegar. Ran machine several times without filter or Kcup by pressing cup selector several times. You must open K-cup holder and close each time. I had to do this about a dozen times before the water began to draw again. Flushed system by filling water reservoir with fresh water, and brewed just plain water until vinegar was gone.Works like brand new.

Descaling light on


Per Pages 9 and 10 of Keurig Model B40 Use and Care Guide,
1) turn off the "Auto Off "feature
2) fill empty water reservoir with 48 ozs of undiluted white vinegar.
3. Place ceramic cup on the drip tray and run a brew cycle. Do not use a K-cup!
4. Press the large mug Button
- let Keurig coffee maker fill mug with vinegar & empty in sink.
5. Repeat brew process until water reservoir of vinegar is empty. (remember to open and close lid between each cycle so large mug Button will flash.
6. Rinse the water reservoir thoroughly and fill with fresh water.
7. FINAL STEP RINSE CYCLE
a) place a ceramic cup on the drip tray
b) run regular brew cycles WITHOUT using a K-cup.
c) pour rinse water into sink each time.
d) repeat brew process until water reservoir is empty.
d) perform additional rinse cycles if you notice any residual vinegar taste.
e) if the red "De-scale" light remains illuminated after completing descale and rinse cycles, repeat the descaling procedure above.
Otherwise - you're good to go!
