My litter robot 3 has stopped working. The blue light is blinking constantly. I have tried all the things on the net eg making sure sensors are clean, drawer is empty, pressing reset and turning on and off but simply cannot make it work 
Hello @hollandlucy,
Welcome back to RobotShop community.
We are sorry to hear that you are having trouble with your Litter-Robot.
Please provide us with your order and serial numbers.
Have you tried to clean the 2 green circuit boards and the 2 plastic brackets of the DFI sensor using isopropyl alcohol and a Q-Tip to remove any rust or dust from them?
If not, please give it a try and let us know how it goes.
Awaiting your reply.
Sincerely,
Hi - the serial number is LR3201135 Model LR3-1000-CE
I have tried everything but simply cannot get it to work - blue light is just continually flashing

Hello @hollandlucy,
Thank you for your reply.
In this case, the DFI sensor will need to be replaced so we will send you a new one under the warranty.
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,
