What Do ‘Fr’ and ‘1r’ Mean on Keurig K-Duo? [Easy Fix]

If you own a Keurig K-Duo coffee maker, chances are you have experienced one of the common error messages. These error messages include Fr, 1r, Add Water, and Descale. Fortunately, these errors can be fixed quickly and easily with the right troubleshooting techniques. In this article, we will discuss what each error means and how to get your Keurig K-Duo working again in no time.

Keurig K-Duo ‘1r’ Error

If you’re experiencing an error 1r code on your Keurig K-Duo, you’ll need to take the following steps to fix the problem. First, unplug the coffee maker from the wall outlet and remove any K-Cup pods that may be inside.

  1. Plug the K-Duo back into the wall outlet and open the K-Cup pod holder lid.
  2. Close the lid and place a mug under the K-Cup dispenser.
  3. Now press the power button on the machine and wait a few seconds.
  4. If the machine starts to dispense water, then the 1r error code should go away.

If you don’t hear anything from the machine, you may have to repeat this process for it to work properly. Once you’ve completed these steps, your Keurig K-Duo should be running! If not, contact Keurig Support.

Keurig K-Duo ‘Fr’ Error

If you see the “Fr” error code on your Keurig K-Duo, it may be due to the coffee maker being placed in a cold environment. This code is likely short for “frozen.” To fix it, bring the K-Duo into a warmer room and let it sit until it reaches room temperature. This could take a few hours or overnight. After that, try brewing coffee again.

Keurig K-Duo ‘ADD WATER’ Error

The most common error associated with Keurig K-Duo machines is the “Add Water” alert. This alert occurs when your machine is running low on water and needs to be filled up. If you see the Add Water alert, check the water tank to ensure it is filled all the way up to the MAX line.

If it is, then try removing the tank and replacing it. If the alert persists, it could mean that the float switch has failed or the machine is not pumping water. To fix this issue, you can follow my related post on how to fix a Keurig that is not pumping water.

Keurig K-Duo ‘DESCALE’ Error

If you’ve completed the descaling process, but the “Descale” message won’t go away, try pressing and holding both the 8 oz and 10 oz buttons for 5 seconds while the brewer is powered on. This should reset the descale message.

There may be a deeper issue if you’ve done this and the message is still present. Using the Keurig firmware update utility, you should first check if your K-Duo is up to date. If your brewer is already up to date, you should contact Keurig customer support. They can assist in determining if a service or part replacement is needed.
