Litter Robot 3 Utimate Troubleshooting Guide

The Litter Robot 3 is an incredibly popular automatic cat litter box which automatically detects when a cat has entered and exited, and rotates the main globe to sift and dump the used litter. It is subjected to conditions which most robots - if they had a choice, would prefer not to be subjected to. There's a lot of dust and debris which can cause issues, which leads to the robot not operating correctly. Customers often search online for a solution before contacting technical support, so this guide is intended to cover the most common situations.

Hi,
I have the above issue, but the topic was just closed up and locked without resolution. Is there a fix other than buying a whole new unit?
Thanks
