My power light comes on, but does not blink or pull water from resouvoir, it is a B40

thats usual

That is a natural occurance.

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?

Clean all ports and reset the pump action as per the manual.

Thermostat has failed replace or repair

Hope this helps

Hi,

There is air in the lines and it is blocking the water flow...
Here is a tip that will help you getyour Keurig to prime...

Keurig CoffeeBrewer will not prime

Try picking up the handle where you put the coffee and kinda slam (not too hard) back down. I found that resets the coffeemaker. Also when you make coffee I also noticed that you when the water is hot you have to pick up the handle again and put it back down then the two blue lights start to blink and you decide what size cup you want.

Lift the handle to open the k-cup holder and then close it back up. The coffee mug lights should begin to blink for you.

Empty the water reservoir and put back on the side of the Kurig. Put your hand in the reservoir and slide the disc that monitors the water level back toward the top and and hold in that position,the machine will think there is water. Then put a cup under the head and select a cup. The water will come out. You must hold the disc up inside the reservoir to continue to get the water out.

If the machine is new, call keurig.. There telephone number is on the web site. They are warrented for 1 year.
