20 Most Recent Keurig B50 Coffee Maker Questions & Answers


Prime means.... pumping. In other words the water in the machine goes through a water pump. That pump, pumps the water from the fresh water container in your machine and pumps it up through the machine, then goes into a heating element that heats the water and then of course flows over the coffee or tea that you put in your machine to give you a nice cup of hot tea or coffee. Priming is in a sense getting the air out or allowing the water to start flowing. If you have a vapor lock or air lock, you need to prime it to kind of help this pump start pulling the water up to the coffee.

Hello, this is common. The pumps on these machines are not real good pressure. Sometimes you have to help it prime for the pump to work.
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 Keurig's 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 descaling the machine every week this will help a lot.

If you find the above helpful please remember to vote for it Thanks Mike

I've got a B50 as well, and none of these solutions are quite accurate. The problem is with the ball valve directly above the top needle. You first need to remove the handle by taking out the screw on either side. Mine is some size of torks. Then open the hood and remove the two screws from under it. The hood then lifts right off the body. There is a rubber hose that goes into the top part of the ball valve; this must be removed. You can then use a slightly bent paper clip to reach in carefully and push the ball down to unstick it. It is being pushed up by a spring from underneath, so coming from the bottom with a paper clip just pushed it up tighter in the seat. Once it is clear again, put the hood and handle back on.

I think Keurig should send free replacement valves, maybe better designed as well so they don't stick anymore. If not, I am going to see if I can purchase a replacement.

According to their tech support...

Remove the water tank and re-seat. Unplug for 30 seconds and replug.

Fixed mine this way with the same issue.

Unplug the unit for 20 seconds- 1minute. Plug it in again. You should be able to program from the menu. Hope this works.

Lift the reservoir, then reseat it. This will clear the prime message. If it repeatedly comes back then your machine is dead. If in the year warranty, call Keurig they will ship you a replacement. A very common problem.

1. Power off machine.

2. Using a metal paperclip, insert it into left side of top needle. It must insert at least 1" deep. Insert it into slot on right side and again from back of needle.

3. Remove KCup cradle. Separate bottom from top. In the top section, insert the paperclip up into bottom needle from the bottom upwards. It will not go all the way thru and this is normal.

4. Reassemble KCup cradle and reinsert it back into coffee maker.

5. Power on machine.

6. Brew a cup of water only. There may be coffee grounds in the water and these should eventually clear during the remaining steps. NOTE: A large cup brew cycle should output a full 8 ounces (235cc). Less means there is still a blockage
