Litter-Robot III Yellow Light Flashing: Troubleshooting – Hard Reset

I was having trouble with our newer Litter-Robot III after I cleaned it and put it back together a few weeks ago. The yellow light was flashing and the globe wouldn’t complete it’s rotation. It’s now working like a charm =)


Here’s the email that LR sent me that I reference in this video:

To perform a hard reset, please follow the steps below:

The globe must be at the Home position with the solid blue light on. With the unit powered ON, unplug the power supply from the base and wait 10 seconds. Plug the unit back in, allow it to complete the start-up cycle, and follow the steps below.

  1. Press and hold Cycle button for 5 seconds. Both blue AND yellow lights are now on.
  2. Press and hold Cycle button for 5 seconds. Yellow light turns off, blue light remains lit.
  3. Activate the cat sensor by pressing on the globe just above the entrance in a forward and down motion. The red light should come on now.
  4. Allow the unit to complete the timing, cycle, and return to home position. At this time, the unit will have reset itself.

If you’ve completed these troubleshooting steps and your unit is still having trouble, you can always contact Litter-Robot customer support.

  1. Hey there. The video didn’t help me. Cause I have a constant blue light flashing. When I press reset it flashes constant yellow then back to blue flashing. Nothing is working. Cleaned . Unplugged. My app is saying my robot is off.

    1. Mine is doing this too. Nothing is working 🙁

    2. Mine is also doing this, did you ever find a fix?

  2. We got our LRIII about a week ago. Today, the yellow light was flashing mid-cycle (for no apparent reason), and these steps didn’t help. However, pressing and holding the Reset button for 6 seconds got the device to spin back to its home setting. I couldn’t find that in the user guide or FAQ, but it’s intuitive and did the trick.

    1. Great – glad you found a way to fix it – next time you can always reach out to their support too!

    Many thanks for the video. The blinking yellow light was getting old, even after taking the unit apart, cleaning and reassy. Very much appreciated!
