"add water" error message.

whats your question how to prime the pump? if so at the bottom is a 3/4 inch plug screwed into it, or at top, once the pump is hooked up to the lines turn off the power, and unscrew the prime plug fill with water, then screw in tight DO NOT USE THREAD SEALANT THEN THROW THE POWER TO THE PUMP, of course house supply valve must be off 3/4 turn valve off until the line is primed then open the supply line to house slowly to supply the water to all the lines, NOTE WHEN YOU FIRST INSTALL A NEW PUMP, HAS TO BE PRIMED, HAVE TO HAVE SUPPLY LINES FROM WELL TO HOUSE CLOSED TO PRESSURE THE TANK AND TO FILL THE LINES.

The water pump system is not primed properly. Remove the water tank while the pump is running and put back a couple of times. If not working, when the power is off, using a straw, blow air through and try to **** through the water port at the bottom of Keurig. Plug the water tank again in and start the system. It will take some time to prime, keep trying. There is nothing wrong with the machine, but the water pump circuit.

Put vinegar in the water tank about 1/4 of a tank and 1/4 of tank water then turn the machine on with the water tank out ( so you don't get the priming message ) then it should tell you fill water tank put the tank in for 5 second and pull it out do it 3 - 5 times ones the vinegar gets in the system let in stay for a wile and then run the rest thrue the hot water and stem works for me I have real hard water at home

Hi That means the pump needs to be primed by running water through the wand. Push the water. You will hear the pump change tone when it primes and the light or message will disappear. If you have a restriction in the intake line the message will not go away. There is a flow meter inside the machine that measures water flow. If the flow meter does not spin when the pump is running, the computer thinks that the pump is not primed. Coffee grounds will get into the intake and restrict the flow meter. If you get a restriction in the water intake (below the water tank, on the machine) the pump may run and water comes out, but the flow meter does not create the jet of water to spin the turbine wheel to send impulses to the computer. You get the ventilate message. One thing to remember is when you are working on the water system (have the water tank off) do not fill the bean hopper and visa versa. Keep them covered when working on the other. Cross contamination will damage a machine fast

What you would have to do is take the side panel off to get at the solenoid. It is probably sticking closed and not letting the water fill into the boiler.

Prime refers to priming the pump. The error message means that there is air in the system which is preventing the pump from pumping water. To correct this, fill the tank with water, press the water button on the right side, and turn the water/steam knob to open. Allow the water to flow until the stream is steady. Press the water button again and your problem should be fixed
