This could potentially be from a problem with the water filter in the tank. Try emptying the tank and readjusting the filter. Sometimes the filter can be shifted when filling and not allow the water to properly flow and give you this display.

Here is a link to the Troubleshooting page. Refer to it for more information.

Tried solutions tried cleaning the filter resetting the machine an the lights were still blinking. Had to clean the needle out.To do this get a standard plastic reusable straw put it up over the needle and blow as hard as you can repeatedly several times. Machine now works fine. Ran three full tanks of water through works perfectly every cup. The needle is the little metal spike that puts the top hole in your kcup. Lift the handle and look under the top , flashlight will help. Hope this helps, only thing that worked for me

Our Keurig did the same thing after doing a cleaning. Put it on the shelf for a month or so, then plugged it back in and it worked! I think some moisture got into the electronics and the month of shelf time let it dry out.

It turns off the lights but when I power back on same issue with descale light. This is a brand new never been used Keurig!!! Maddening!

by

Same here. Cleaned it, use a paper clip, pushed two buttons with the power button, lights are off but will not turn on. Unplugged it turned it back on, all lights are on but not working. It all started when I tried to clean it with some vinegar. About 4th one I've owned in the past 10 years. Going back to the old coffee pot.

by

Have you checked and cleaned the needles on the top and bottom? When they or just one becomes clogged, that will cause a malfunction. Also let it set unplugged for a day or so after checking the needles. I hope this helps you and you're able to enjoy the fresh brew that only Keurig can give.

by

Also be sure you raise and lower the mechanism that holds the pods!! That makes a big difference.

Stopped it from blinking now I just have the power button comes on and the heating light comes on what size of the cup lights don't come on so it's not going to run no water through without those buttons

Had my pot unplugged while on vacation. Plugged in to make coffee (I need home coffee!) I've done the button thing many times. Also poured out water and gave it fresh water. Nothing. Still blinking and no coffee. It doesn't make any sound either.

by

I came home to the same thing, clean the needle the k cups punch thru, that’s the only thing that worked for me!
