Causes Of Keurig All Lights Flashing

There are several potential reasons why your Keurig coffee maker is experiencing the all lights flashing issue. We’ve outlined the most common causes below:

  1. Water Reservoir Issues: The water reservoir may not be seated correctly, or it may be empty, triggering the all lights flashing signal.
  2. Debris or Scaling: Mineral deposits or debris within the machine can interfere with its proper functioning, causing the lights to flash.
  3. Software Glitches: Sometimes, a software glitch can cause the Keurig all lights flashing issue, which can be resolved with a reset.
  4. Internal Malfunction: In rare cases, an internal component failure may lead to the all lights flashing problem.

How To Fix Keurig All Lights Flashing

Now that you know the common causes, let’s explore the steps you can take to fix your Keurig all lights flashing issue:

Check The Water Reservoir

The first thing you should do now would be to check the water reservoir. Follow these steps:

  • Switch off and unplug your Keurig coffee maker.
  • Remove the water reservoir by gently lifting it from the machine.
  • Examine the reservoir for debris or damage that may be preventing a proper seal.
  • Fill the reservoir with water, ensuring it meets the minimum fill line.
  • Place the water reservoir back onto the machine, making sure it is seated correctly and clicks into place.
  • Plug in and turn on the Keurig. If the all lights flashing issue persists, move on to the next step.

Clean And Descale

Cleaning and descaling your Keurig coffee maker is another solution that can help you fix this issue. Here is a step-by-step guide on how to do it.

  • Turn off and unplug your Keurig coffee maker.
  • Remove the water reservoir and empty any remaining water.
  • If your Keurig has a built-in descaling feature, refer to your user manual for specific instructions.
  • If your Keurig does not have a descaling feature, prepare a descaling solution by mixing equal parts white vinegar and water (e.g., 1 cup of white vinegar and 1 cup of water).
  • Pour the descaling solution into the water reservoir and place it back onto the machine.
  • Plug in and turn on your Keurig.
  • Place a large mug on the drip tray to catch the liquid.
  • Run the brewing process several times, using the largest cup setting, to allow the descaling solution to flow through the machine and remove any mineral deposits.
  • Once the solution has been used, repeat the process using fresh water to rinse the machine thoroughly. You may need to run several brewing cycles to ensure all traces of vinegar have been removed.
  • If the all lights flashing issue continues, proceed to the next step.

Reset The Keurig

Resetting your Keurig coffee maker can help you fix the issue quickly and easily. Here is how to do it properly.

  • Turn off and unplug your Keurig coffee maker.
  • Wait for at least 5 minutes. This allows the machine’s internal components to cool down and reset.
