Question about Keurig Elite B40 Coffee Maker

2 Answers

Does not dispense water unless you pinch vent in water tank.

After pressing BREW, water does not dispense. At the end of the cycle, the coffe maker pupmp would come on as expected and would try to refill it's internal tank - but would stop quickly and the display would soon show READY and only the largest cup icon in the display. Trying again, and noticing water dripping fron the vent in the reservoir, I plugged the vent during BREW and coffee started coming out of the dispenser. If I do this everytime, plug vent during BREW and leaving it alone during the pumping, it seems to work Ok. Any ideas?

If your Keurig is putting water out the vent and back into the reservoir. Open the front, using a flashlight and a toothpick, clean the coffee grinds out of the little hole in the needle that pierces the K cup. When it becomes clogged with grinds the water either has to come out the vent or the coffee maker will burn out. It is a safety mechanism.

It sounds as though the valve between the resevoir and the vent may be bad or stuck in the open position. If you read my earlier posts this would stop any vacuum from being created in the resevoir until you "pinch" off the vent. Changing this valve is tricky but very doable. The problem is getting parts which is near impossible. If you have or had a warranty call Keurig direct.

Keurig b60 won't dispense water

Your b60 may need to be descaled. There might be scale built up on the water level probes in you machine. I have listed the directions below:

Brewer De-Scaling Instructions
Brewer Model: Elite B40 ' Classic B44
Special Edition B60 ' Platinum B70
To begin, you will need the following:
• 48 ounces of undiluted white vinegar
• Large ceramic mug (do not use a paper cup)
• Access to an empty sink
Step 1:
Empty the water in the Water Reservoir.
Step 2:
Disable "Auto Off features."
Step 1:
Pour approximately 48 ounces of the vinegar
into the Water Reservoir.
Step 2:
Place a large mug on the Drip Tray Plate and run a brew cycle.

, just press the BREW Button. Pour the contents of

the large mug into the sink.
Step 3:
Repeat the brew process without a K-Cup until"ADD WATER"

is indicated.
Step 4:
Now let the Brewer stand for at least 4 hours while still on.

Step 5:
Discard any residual vinegar and rinse the
Water Reservoir thoroughly.
Step 1:
Ensure the Water Reservoir is filled with fresh water.

Step 2:
Place a large mug on the Drip Tray Plate and
water brew cycle. Pour the contents of the
large mug into the sink.
Step 3:
Repeat brew process until "ADD WATER is indicated.

Step 4:
You may need to perform additional water brew
cycles if you notice any residual taste.
If "DE-SCALE" is still displayed after
completing the procedure, repeat the
descaling procedure above.

How can I clean my bunn vp17-2 coffe maker the water will not leave the holding tank to go to the filter

First make sure you have enough water in the machine. It holds about 2 and a half pots of water in the holding tank. If the machine sits for a week without use but is still plugged in, sometimes the water will evaporate down to the point where pouring one pot of water in, will not fill the tank back up. If you still don't get a water flow, take the brew funnel out and reach up where the water normally comes out, There is a round water dispenser about 2 inches in diameter. Unscrew it by turning countercloclwise. It has a dozen or so holes where the water come out. Be sure these holes are not stopped up. There is a small pipe fitting where you took the water dispenser off. Bunn makes a long spring like thing that fits into this hole to remove built up lime deposits. If you don't have one you can use a flexable wire like braided copper wire about 18 inches long to push through the hole and slide it back and forth until it comes out clean. If you have hard water, like well water you may be getting a lot of calcium build up in the tank. Put about a quart of vinegar in the next coffee pot and let it sit an hour. Pour water through the machine until it stops smelling like vinegar. That should solve your problems.

Coffee is coming out all around the coffe dispenser and very little through the dispenser.

brew unit filters are blocked. take out brew unit, remove screws and clean and replace stainless steel filters.
