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
