Question about Keurig Platinum B70 Coffee Maker

1 Answer

My B70 loses prime when drawing water from the reservoir. After a few seconds of the pump running and no water being pumped, the unit will automatically shut off. The reservoir is fully seated. Does anyone else have this problem?

The problem might be common however, Keurig does not have any repair centers around the country, nor do they have schematic drawing available :(. In order to get your problem taken care of you have to call Keurig directly 1.866.901.BREW

Keuring coffee maker B60 B70 B77reservoir full but fails to refill, brewing...


After a brief investigations found out that this is a design problem for all the newer Keurings like B60, B70, B77, Keuring factory after a lot of complains of a noisy refill pump this is the pump which pressed water from reservoir tank into the brewer. (Please to mixed it with the second pump that presses the hot water through the K-cup this is a different one).
In the place of that pump now they are using a small DC motor and impeller pump, which is much quieter however the new design just won’t work.
It seems that we have air that gets into the system and the new pump isn’t strong enough just to SELF-PRIME with this way. With this way the motor still runs, runs, runs but water is not going through it and finally it turns itself OFF in order not burn out. Normally it should take only few second to refill the brewer tank.

There were many options that the problem was due to the check valve located in the base of the unit just below the reservoir seats itself. However actually this small new pump cannot press hard enough to open the check valve so the water can easily flow. If there is air in the system or slightly scale this make it harder.

I have found out that that the problem occurs only just a few weeks after we use a brand new machine.
So one very good way to solve the problem is to turn the machine on and lift the water reservoir up just a couple of inches and then jam it back in place fast and hard. With this way is like it injects just enough pressure into the system to open the check valve and when the motor pump will run you will realize that immediately water will passing through from reservoir to brewer tank. This procedure has to be done often between cups.

From what we seen in internet their hundreds about the same problem but we have not see any serious response about it From Keurings customer service yet.
One other important and related problem frequently reported is the irregulars doses of coffee like HALF-FILLED CUPS of coffee e.t.a

This must be redesign from Keuring factory since there is not much we can do about it to solve once for all even if they will replace your machine with a new one you will have the same problem in few weeks. And definitely this not a problem due your Electricity in your area or due to hard water. However hard water areas will face bigger and more intensive the above problem so one more suggestion is to decaling the machine every week this will help a lot.

If you find the above helpful please remeber to vote for it

My keurig b70 coffee maker says prime. sounds like the pump works for awhile then stops. prime lights up on the screen and doesnt let me do anything else why


Mine would brew the first cup fine, then the pump would run but would not draw water from the reservoir. I turn it off, turn it back on it would draw water for one cup then would not draw water again. I unplugged it waited 30 seconds and plugged it back in, assuming that would reset the electronics. It worked fine following the PDPU (power down, power up) procedure. Simply turning it off will NOT reset the processor, you MUST unplug the unit. Remember to wait 30 seconds or so prior to plugging the unit back in.

Pump does not pump anything. motor is running and getting hot, no water being pumped. i have to prime this stupid thing?


If you are trying to draw water from a lower place, you may have lost prime. It is also possible there is a reason for this loss of prime, maybe a leak on the suction piping. Remove some fitting on or near the discharge of the pump, fill the body completely with water. If it goes in, fill the entire suction piping with water, too. Open a faucet nearby, turn on the pump and wait up to 5 minutes. It should spit and sputter, sound will change, some water will discharge, but eventually, you should get steady flow.
If you lose prime again, look for leaks in the suction piping from the inlet of the pump to where the piping goes into the ground.

My B70 just starts running water through and doesn't stop till it's drained the reservoir...Any clues?


I have taken the beast apart and watched it successfully cycle and fail to cycle.


Warning!!! (DO NOT TRY DIS-ASSEMBLY IT UNLESS YOU KNOW EXACTLY WHAT YOU ARE DOING AND RECOGNIZE THE COMPONENTS, You could electrocute yourself and suffer nasty permanent scaring... ouchie!)


I discovered the same as another person claimed a "check value" and/or air leak/lockup. The pump cycles, but can't get water so the machine shuts down to prevent over-heating. (The dreaded "Not Ready").


Solution...


1. Turn off the machine and unplug until it is completely cooled, say 4 hours. (Allows for temperature equalization of the water chamber and the water supply)


2. Completely fill the water reservoir. (The extra water just helps the pump break the air lock).


3. Turn the machine on and wait for the pump to start drawing water.


4. Immediately knock 1-3 times on top of the water reservoir/machine (at the very top of the machine) about as hard as would knocking on a door. (Watch the water level, it should immediately start to drop)


The pitch of the pump should change when the water begins to be drawn into the heating chamber. (you can also hear the water flowing)


The problem is caused by air entering the water supply system. This air provides a "lock" on the system that the pump can't overcome. This can happen due to a number of issues but most issues should be this easy fix.


The machine refills itself 3 times. At Power-on, at beginning of the brew cycle and after the brew cycle.


Watch the machine and any time the pump cycles make sure it draws in water until it shuts down, if it doesn

Pump is running but no water is being drawn from the reservoir


I haven't had this happen where nothing is being dispensed, but if you have small portions being dispensed or the pump is noisy, I tried 2 things that work for me:
1) remove the reservoir and over your kitchen sink, with water still inside the reservoir, use your pinky finger, small chopstick, etc, and gently push the inlet valve a few times from underneath to let water out. After about 2-3 months, our unit seems to stick (rubber seal that closes),
2) put some vinegar into the reservoir with some water and run the unit about 3-4 times on largest cup setting. Clean out the reservoir, replenish with fresh water and run the unit another 6 times. Believe me, you need to flush the vinegar out well, otherwise any residue in your coffee will not only taste bad, it will curdle your milk/cream. I've had my B70 Platinum for 15 months making about 8 cups everyday, Hope this helps..:D

Water not pumping through, though steamer works and it makes noise.


You need to get the pump "primed" with water going through it.

If the machine is new or has not been used in a long time, the plastic feed tube(s) in the reservoir will be dry. You have to get the water to slowly creep up these tubes until it hits the pump inside, then the water/steam will come out the head and will keep coming out each time you use it until it dries out again.

I've had to re-prime my Via Veneto several times, and each time it seems like I'm doing it wrong and the machine is broken. But follow these steps and you'll get there.

1. Fill the reservoir with water and put the two tubes in it.
2. Turn on the boiler button (left-most of the two narrow ones)
3. Don't put the portafilter on, just leave the head bare.
4. Turn on the pump and let it run. Watch the water level in the plastic tubes. Understand that at this point, the pump is just pumping air, which it is not designed to do efficiently. As it pumps the air it slowly draws water up the tubes. Really slowly.
5. You can speed this up by putting a cup under the steam tube and opening the steam valve. This is while the brewing pump is still on. You will have hot water squirting out of the steam tube. You may see the water moving more quickly up the tubes.
6. The pump may have to run for several minutes. You'll get impatient and scared something is wrong, but just let it run. You'll see the water creep up the tube and go into the unit. Soon afterward pressurized water will start spraying out of the head.

Now, keep it primed for months by keeping water in the reservoir. If you use it only infrequently, run the pump and at least get some water moving every week or so.

I've tried silly things like holding the tubes upside down, trying to get water forced up into them, but in the end, just let the pump do the work and be patient.

New Keurig B140 will not pump or prime


On the water reservoir there is a little black disk, a magnet, I think... If that is not against the machine it will display the prime error. Empty the water from the reservoir and tilt it so that the disk is against the machine. Place the reservoir empty back on the machine and fill it with water carefully as not to move the disk. When the water level gets to the correct position, the prime error will go away.

Priming problem


Make sure you try to prime right when the machine is turned on, so that there is no boiler pressure making it more difficult to prime.
