Thanks in advance anyone who helps
my litter robot 3 completed a 360 degree cycle instead of regular cleaning cycle, I unplugged power supply then plugged it back after 10 seconds, it starts to cycle then stops at midcycle with upside down, solid yellow light on for minutes then quick flashing yellow light, I had bypassed anti-pinch sensor by adhere with duct tape and I replaced anti-pinch sensor couple weeks ago.
what could be the reason causing it? Any advice is appreciated.

Hi Ebram, thanks for the reply
control panel isn’t overheated
All sensors are clean
I couldn’t find that 5 screws on chipboard maybe because It is a connected version (I’m not sure) ?
When I plug power sub my on, it starts with solid yellow light but globe not missing, then It turns to flashing blue red yellow simultaneously
I have checked position sensor, the condition location and orientation are fine

Do you hear the motor trying to rotate?
Please provide us with a picture like the one attached below of the power adapter:

I don’t hear motor trying to rotate. My litter robot is quite weird today, firstly it rotated 360 deg then quick flashing yellow, I unplugged power supply checked Antipinch detector is good, then globe rotate stopped at mid cycle and shown solid yellow. I unplugged power again, it shown solid yellow light without any motion, few minutes later blue yellow red flashing sequentially. Now it’s solid yellow light without rotating then 3 lights flashing simultaneously

Hi Ebram, hope you are doing well
I have replaced required components, however, when I plug power supply it’s quick flashing yellow light. The anti-pinch sensor are new, I replaced them couple months ago, so I use duck tape to adhere those 2 sensors together, plug in power, it’s solid yellow light but not cycling, I don’t hear any sound of motor trying to rotate. While power is plugged, I try to detach 2 anti-pinch sensor from bottom of machine (waste drawer), in my understanding, yellow light should be quick flashing if anti-pinch sensors are not connected, however, control panel still shows solid yellow light no matter sensors are touching each other or not touching. Could you advise what’s the reason of it? Appreciate your help.
Hello @Gingersoupsoup ,
Thank you for your reply.
We are sorry to hear that you are still having trouble with your Litter-Robot.
Does the area between the buttons heat up quickly once you turn the robot on?
Please provide us with the order number for the new parts and pictures like the ones attached below to verify the installation:

Hello @Gingersoupsoup ,
Thank you for your reply.
According to the pictures, we have detected multiple issues:
1- The base contact pins haven’t been replaced and their connectors are reversed so you will need to install the new ones and adjust the connectors to look exactly like the one below:
2- The Anti-Pinch pins aren’t installed properly so please refer to the video below to show you how to install them properly:
3- The red motor wire has gotten entangled with the motor shaft and it might have been damaged in this process so you will need to gently untangle it then check the wires connected to the motor and make sure it’s still well-connected then install the wires beneath the motor as shown in the motor replacement video below:
Let us know how it goes.

Hi Ebram, thanks for your tutorial, I have replaced contact pin and corrected cable. For anti-pinch pin, I have it tight attached with each other securing with duck tape. and untangled wire, please see attachments. It is still solid yellow light without any motion or sound
Hello @Gingersoupsoup ,
Thank you for your reply.
Please only use colorless ducktape with the hall-effect sensor.
Also, it seems to be still in the wrong position so please adjust it so that the orange wire would be on the inside next to the yellow wire as shown in the video below:
Let us know how it goes.
