We had a question yesterday from Randy who had a problem with a very poorly Keurig B60 and the dreaded Keurig blinking lights problem …: “My Keurig stopped working. It has the “ready to brew” light on and the three-cup size lights blinking. You can’t turn it off, and the menu button or any other button won’t work. Is there a reset or something I can try?”.
It wasn’t an issue that we had covered before, and so we thought we better get to work. We wanted to find a solution that would get Randy back to making his regular Keurig coffee. Having worked through different solutions with our trusty B60 testbed, we have a solution that fixes the blinking light problem.
Keurig Blinking Light Cause
The cause of the blinking lights situation with a Keurig brewer is the machine unsure of its next step. This is usually the result of an interrupt to whatever it was working on. The interrupt could be from a power change, a break in a sensor signal, or just a bad day! Most people don’t realize underneath all that plastic is an 8-bit PIC Microcontroller that manages all the functions going on. And sometimes this unit can get itself a bit worked up and hence the flashing or blinking lights.
A Solution to the Keurig Blinking Lights
The following solution was designed to enable a Keurig brewer’s “brain” to be reset and get it back into its normal mode of operation.
Ensure the brewer is turned off (and at this point, the lights should be blinking, and the brewer isn’t in the middle of any other operation).
Press and hold the auto-off button.
Press and hold both cup-size buttons (for those brewers with only two cup sizes). For those with three cup size selections, press and hold down the medium and large cup size buttons.
Once all the lights go out, release the buttons. The brewer should now turn itself back on, and you should be able to get back to making coffee. If the brewer doesn’t turn on automatically, press the power button.
As with all of our work, we would love to hear from you. In particular, if a proposed solution worked or didn’t work for you. Please use the comments section below or the Contact Us form.
