Why are all of the lights blinking on the Keurig?

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.

Press the AUTO OFF AND TWO CUP SIZES BUTTONS AT THE EXACT SAME TIME! THAT WILL FIX IT!!

This one s the only thing that worked for me .

Get a bendy straw, put 1 end over the piercing nozzle in the top of the Kuerig lid, hold the straw tightly against the nozzle and blow into the straw. It took me several times but it did work and I have used this method a couple of times and it worked great

I did a desaling from the directions on the package and now my machine won’t turn on and when I lift the handle all the lights on the cup amounts blink and then shut off but it won’t work or brew

There is a small push pin type switch the lid pushes when it closes. That allows the brew cycle to start. This is not happening on mine, so I placed a small nut on it so the lid will push it down. It works, but how was it designed to work?

Just ran vinegar through it a few times, and then xlear water to rinse. And the stupid thing stop working. All lights blinking

If all lights (add water, heat, and medium cup size buttons) on your Keurig coffee machine keep flashing, then there might be a problem with the water filter or the needle.
Try Cleaning Water filters first if that doesn't work then clean the needles. Hopefully, it will solve the problem. This article might help you:
Why My Keurig Lights blinking

KURIG YOU HAVE A PROBLEM.!!!

The k model i have is a year old . It was blinking descale and i descaled it 10 times . Now get double flashing lights on all brew sizes ( they flash twice then off ). Here's why .

My brewery sat for 6 months unplugged and lost the descale program. Now it will not keep tract of how many cups and program is not resetting . Oh I can make it flash the descale and it goes thru regular recycle like it should but the descale program does not reset thus the double flash .

The maker is programed at the bottom of maker you'll see a little door . Open it with screwdriver and you'll see where they connect to program the EPROM chip .

Here's why the program got lost .

There's a chinese capacitor acting as a backup battery for the Chinese made EPROM chip which has the program. When the capacitor looses charge thru time good by program . Good by coffee maker .

Kurig you have a problem and from what I'm reading it's very common . Should have went with an SRAM chip. No capacitor needed !

Should be sued .

Mine did the same thing after carefully following descaling instructions. I have no idea what else to do. I have tried unplugging, removing the water, pressing the reset inside in the machine and nothing. The only thing it does is descale if I press 12 & 8 again but no coffee brew it turns off. I can not believe this.
