I saw this statement “I descaled my Keurig and now it doesn’t work” appear a few times in a thread on our coffee community.

This post is a response to the question posed. All is not lost as this is a problem that is easily fixed.

Keep reading and learn the options that you have to fix this worrying problem and what caused it.

I Descaled My Keurig And Now It Doesn’t Work

If you have given your Keurig a real good descale, and it is not working, the reason may be the thermal switch tripped during the descaling process due to the machine overheating.

In this instance, all that is required of you is to wait and let your machine cool down. The thermal switch in the majority of cases resets itself. Unplug your machine and just wait for a couple of hours.

Then plug your machine back in.

In the event of the thermal switch not self-resetting, the only solution is to call customer service if your machine is still under the one-year post-purchase guarantee.

If it is not under warranty or guarantee, you can attempt to disassemble the machine and reset the thermal switch back using a paper clip.

When you have done this, you can get back to running the descale process again. The next time the descale light comes on it will act like it did the first time and will try to drain the unit without warning.

Your Keurig machine may also not be working due to having overfilled the water reservoir, using the wrong coffee pod or debris clogging your needles.

Ensure that your water tank is not too full; check that you are using the correct coffee pods.

Another peculiar culprit is the water filter needing to be replaced. Remove it and replace it. Clogged needles may need to be cleaned and unclogged too.

Keurig Supreme Plus Won’t Turn On After Descaling

If your Keurig Supreme Plus won’t turn on after you have run a descaling cycle, you will need to open up your coffee maker to access the thermal switch. Push the disk on the thermal switch to put it back to the regular position. You will need to use a fine needle or a paper clip.

Don’t forget that you will need to run the full descaling process again.

Instructions

  • 1. Unplug your coffee maker and remove the screws and save them.
  • 2. Remove the casing using a small screwdriver.
  • 3. Locate the thermal switch. If you are unsure of where it is, check the owners manual.
  • 4. Get a paper clip and insert the end of it into the center hole. You’ll hear a strange sound.
  • 5. Plug your machine back in and test to find out if it is starting up. Press power and check and see if everything is okay.
  • 6. Reassemble your machine and put everything back as it was and should be.

Pro Tip: The thermal switch is usually attached to the inline heating tube. Look for a spiral heating element.

Keurig Won’t Turn On After Descaling Some Tips

Avoid re-running hot water and vinegar through your coffee machine as it will eventually cause the thermal switch to overload and trip, which means after descaling you won’t be able to turn it on.

If you need to run a second descaling cycle with vinegar and water, wait for half an hour and let your machine cool down first.

  • Never reset your Keurig when it is plugged in.
  • Always ensure that there is enough water in the water tank at every step of descaling until the whole process has been completed. Your Keurig can burn out if the water runs out.
  • To avoid taking your machine apart and descale immediates when you see the descaling notification.
