B70 says it is brewing. Hear it draw water but it does not come out. Manually unplugging and plugging back in fixed most recently. Can anyone suggest what menu setting is getting off and how to correct this?

On my fourth machine...just call keurig...they will replace it. THEN use only bottled drinking water (buy at store buy the gallon). I have done this for over a year now without any problems. Apparently my water had some hardness to it that plugged the line internally. My machine would draw a little water and no water would come out and the default cup size was set to large and could not change. I guess because the internal resivour (sp) was already full and there is no way to empty 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.

My B70 does not brew anymore. I've had this problem with two other B70's which I returned. I've been able to nurse this third one along, but it finally gave up. When I press the brew button...

This is a common fault with these as the pumps rust very easily which causes them to seize.

Depending on your technical ability you could try and strip the unit and either clean or replace the pump.

I can't find any further information on a replacement pump for this model but if you do decide to strip the unit you should be able to get a Model No off the existing pump which is more than likely an ULKA..

Here's a link to instructions how to strip the unit.

If you need any further assistance then just ask.

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").


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

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...

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

Coffee maker says it is brewing but it won't draw any water from the resevoir. we have cycled it on and off, unplugged it, etc. It is only 1 month old and has worked fine until this morning

What Model? These brewers (B70 & B77, usually from Costco) are defective & Keurig is replacing them with new units @ no cost. Just call the toll free # (866-901-2739) & they will ship out a replacement in 3 to 10 business days. I own (2) of these & they have both been replaced. Even if not the above mentioned models, call anyway & see if they will replace it.......
