Litter Robot 3 - Orange LED blocked and nothing respond even power button

Hi there,

I’m happy to join the RobotShop community, cause today I need some help for troubleshooting and repair my cat’s Litter Robot 3, I did not find anwser on the forum yet.

Initial trouble :
I found the Litter Robot completely stuck in this position, with the orange LED quickly blinking (4 times / s) and all 3 buttons not working (cycle, reset and empty) :

After turn it off and on with the Power button, the Litter Robot was stuck with a fix blue LED :

Then I unpluged the power form the outlet and re-place the bowl manually in initial starting position after removing the bonnet.

What about now ?

  • The Litter Robot auto power-on when plug-in the AC power, with a fix orange LED, and everything stucks : no motor moves, not any buttons works, even the power button, impossible to turn the robot off except when unpluging the power cord.
  • After waiting the whole night with the power unpluged, the robot turn on after pluging the power cord and pressing power-on button, but with a blue quick blinking LED (4 times / s). If I turn it off with the power button, I return stuck to the previous point when power it on again.

Things tried and checked for troubleshoot the issue :

  • Installed on a flat floor with nothing touching the robot
  • Main Power output voltage : 15,06 V
  • Empty the drawer
  • Clean the drawer sensors
  • Use a vaccum to remove the litter dust
  • Continuity test of the contact between the bonnet and the base : OK
  • Voltage delivered to the motor wires (green and brown) when stuck with orange led : 0,00 V

Order references for the support :

  • Product name : Litter-Robot 3 Automatic Self-Cleaning Litter Box EU
  • Order number : #1035235

Thanks you very much in advance for your precious help :slight_smile:

Hi @Ebram ,

Thanks for your help !

I tried to unplug the DFI sensor connector from the motherbord, and then power-on the robot : no more orange LED stuck, and I can power-off and on the robot by using the power button. Of course the robot still does not work, and show a blue blinking LED, but I guess its normal with no DFI sensor connected :wink:.

Does it confirm actually that the issue come from the DFI sensor as you told me ?

One last question : the DFI sendor on the website ( Matériel Litter-Robot 3 Open Air DFI (v2) - RobotShop ) looks very different from the one I have I my Litter Robot 3, mine is longer, exactly like the one showed in the video you share. Is the webite photo non-contractual or is it even compatible version ?

Thanks for your support :slight_smile:
