Add water, Heating, and Medium cup buttons flash but no coffee!

I see this is an old post but just in case anybody else runs across it I had the same problem. When you remove the top cover of the water reservoir the Overflow elbow at the top of the reservoir should be clear silicone looking plug your finger over the top of it open the Keurig K-Cup holder close it back hit the Brew button with your finger still held over the elbow and it should Purge the air from the line and get you back to working

"While it’s doing all that blinking and humming:

Take off the reservoir lid.Grab hold of the reservoir with one hand and pump the tank up and down (basically lift the tank up a little and bring it back down, over and over).At the same time, with your other hand, cover the overflow elbow plastic tube at the top of the reservoir. You’ll feel a slight suction the more you pump.Hopefully one or both of the cup buttons are lit-press one when it’s trying to pump the water through, cover the elbow again here and there to create suction. Water should flow through where the coffee goes.

Side notes:

This is the model with just two size cup options, power and auto off buttons, and lights for add water, descale, and heating.

Problem:

When turned on, it would hum for a while before any other light would come on. When it did, add water, heating, and one cup light were blinking. Water would not pass through.

Tried:

Cleaned out the needle part with a paperclip.

Opened the top part and squeezed the tubes in case there was blockage.

Pressing auto off and power button at the same time.

All the tips and videos I could find, etc, but maybe they all helped contribute to fixing it but it wasn’t until I pumped the reservoir AND covered the elbow that it worked.

GOOD LUCK!"

"I also had this issue and tried all of the above solutions to no avail :( I called the help line and what they told me worked!

Unplug your Keurig.Straighten out a bobby pin.Open the lid and locate the needle that enters into your k-pod. Be careful, this is extremely sharp!Use your bobby pin and insert it into the 2-3 holes (depending on your model) in the needle. Do this for each hole 10-12 times.Plug in your Keurig and brew a few water only cups until the water is clear and free of coffee grinds.Enjoy your coffee and clean Keurig."

Had same code. The top needle that punctures the K-Cup was clogged. Turn off..Remove water tank... Open K-Cup basket... Tilt machine back enough to see pin.... Carefully insert a needle or pin to clear the obstruction. I then ran a few large cups through with No cup in basket to flush out the grounds. Repeat if necessary.

Jason's method solved my problem!! I tried all other options before his post, then voila. I'm having a cup of coffee!
