Hi!
I require your help regarding a problem I’m encountering.
My Litter Robot 3 is on constant solid yellow light and stopped midway through cycle. No further movement, no reaction to any buttons, no reaction to hard reset. I’ve checked the cat sensor with a multimeter - the circuit over the metal bars is closed.
My Litter Robot is just over 2 years old. Never had problems with it so far.
Thank you so much in advance for your help!
When I wrote checking the cat sensor, I meant the pinch pins…
Hello @Spookey,
Welcome to RobotShop community.
We are sorry to hear that you are having trouble with your Litter-Robot.
Please provide us with your order number or a copy of the invoice.
Let’s try with a simple test:
Unplug the robot.
Remove the bonnet and globe.
Follow this video to open the top part of the base:
Replacing the Motor | Litter-Robot 3 - YouTube
Disconnect the DFI sensor from the circuit board as indicated in the picture below:
Plug the robot back in and check if the solid yellow light would turn into blue blinking light.
If you find this too complicated for you, you can send us the robot for repair.
Awaiting your reply.
Sincerely,
Yes! When unplugging the indicated connection the blue light starts blinking!
So what does this mean?
Hello @Spookey ,
Thank you for your reply.
It means that the DFI sensor is the one causing the issue.
This video will help you locate the 2 green circuit boards of the DFI sensor:
Locate the board on the right side of the robot (the one next to the Anti-Pinch pins) then send us a clean picture of it from the front so we can check if it has any visible damage or not.
Keep the robot disassembled in case we needed to check something else.
Awaiting your reply.
Sincerely,
My LR3 only has one board, it is located on the opposite side of the pinches. The pinches are connect via 2 cables to the board on the other side
Hello @Spookey ,
Thank you for your reply.
In this case, you are still having the LASER DFI sensor.
This board has a small circular sensor in the middle that you can clean with a dry Q-Tip.
If that didn’t fix the issue, you will need to replace the DFI sensor with the newer version which has 2 circuit boards, one on each side.
We will need your order number or a copy of the invoice to check your warranty.
Awaiting your reply.
Sincerely,
Hello @Spookey ,
Thank you for your reply.
We didn’t find any information tied to this serial number.
We need your order number to be able to check the warranty on this robot.
You can provide us with the email address that you used to order this robot or the full name used … or even the phone number to help locate the order number.
Otherwise, we can consider the robot out of warranty and resume with the troubleshooting.
Have you tried to clean the DFI sensor as we instructed? Did it work?
Awaiting your reply.
Sincerely,
Cleaned the sensor- no improvement.
Hello @Spookey ,
Thank you for your reply.
In this case, you will need to replace the DFI sensor.
We will also need to see the 3 pairs of contact pins shown in the following videos:
Anti-Pinch Pins:
Bonnet’s Pin:
Base’s Pin:
No need to take them out of the robot, we only need to see them from the outside.
Awaiting your reply.
Sincerely,
