I require your help regarding a problem I’m encountering.
Description: My litter robot 3 recently started flashing the blue-yellow-green “cannot find dump position” error code and won’t cycle after the cats use it. If I press “reset” and then “cycle” it will cycle as normally (or almost as normally, see below) but when it returns to the home position the same error lights start flashing again. One thing I have noticed is that, when it is cycling and it reaches the end of its first turn, there’s a short squealing noise and the dome over-rotates slightly before rotating back.
Hardware concerned: Litter robot 3.
Software concerned: N/A
Troubleshooting steps already taken: I have taken the following steps already mentioned in a few similar posts:
unplugging it and plugging it in again
cleaning the unit
slightly opening the pin in the power jack
making sure that it is plugged directly into the wall using its original power adaptor
making sure that the unit is on level ground and not touching anything else
checking the motor gear to ensure that it is tight and not free-spinning, and
making sure that the globe is properly aligned in the groove on the base.
Additional information: A number of other people have reported a very similar issue so I’m hoping that this is a known issue!
Sorry I’m a little late in responding, but I just wanted to thank you for the information.
I’m a bit late because it’s taken me this long to actually try the fixes you recommend (for the past few months I’ve just been resetting it every time I check and then pressing the “cycle” button; this worked, but obviously wasn’t a permanent fix). So when I finally decided to try to fix it, I checked the magnets and they were fine, so I ordered the wiring harness and installed it today, and it worked!
The wiring part was a little fiddly but everything was pretty straightforward. And a $20 wiring harness is definitely a lot better than buying a whole new machine.
