Litter Robot 3 - Fast yellow flashing light issue

Help & Support Domestic Robots
1

Hi!

On my LR 3, the blue light is flashing slow, also after restarting the robot. When I press “Reset”, the yellow light starts flashing fast (I guess 3-4 times per second).

It looks like I have a similar error indication as in Litter Robot Open Air trouble shooting yellow light flashing. I tried all troubleshooting steps there. It does not seem to be:

  • the bonnet connector (cleaned and adjusted a little bit with a screwdriver)
  • the pinch sensor (cleaned and adjusted, also tried to bypass with a direct cable so there is always a physical connection between the sockets)
  • checked the DFI sensor boards, they look good and to my understanding they would not cause a fast yellow flashing light (only slow blue)

Is there anything else I can do to troubleshoot? Are there more options to debug and identify which sensor might be broken?

Thank you so much in advance for your help!

Hello @durroon ,

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.

You can clean the 2 green circuit boards of the DFI sensor with isopropyl alcohol and a Q-Tip to remove any rust from the small pins.

Sometimes, these pins get rusty and connect to each other causing the robot to malfunction.

Here’s a video to help you get these boards out to clean them:

Awaiting your reply.

Sincerely,

Hi @Ebram . Unfortunately, the fix did not last long. The LR stopped working with the Same error. I tried cleaning the Boards and the pinch again, but no luck. Do I need a replacement for the boards?

Many thanks in advance!

Hello @durroon ,

Thank you for your reply.

In this case, the DFI sensor needs to be replaced.

Are you able to replace it at home if we sent you a new one or do you prefer to send us the robot for repair under the warranty?

Awaiting your reply.
