Liter robot 3 lights blinking in a Row

Hi!

I require your help regarding a problem I’m encountering.

The lights in the robot keep blinking one after another: blue/ready, yellow/cycling and red/timing, and then blue again. After reset the robot workshop again for a few hours and then starts blinking again.

Thank you so much in advance for your help!

Hello @BaertBenedikte ,

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.

Are you using the original power adapter and plugging it directly into the wall?

Awaiting your reply.

Sincerely,

Yes we use the original adaptor that is well connected to the socket.

Hello @BaertBenedikte,

Thank you for your reply.

This issue could be coming from 3 parts:

1- The contact pins.

We will 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.

2- Magnets inside the globe.

Please test the magnets by putting any metallic object on these two areas circled in red and check if the magnets would attract the object or not.

Globe Magnet 01
Globe Magnet 02

3- Misplaced or defective hall-effect sensor:

If the magnets are okay then the issue is coming from the hall-effect sensor and it needs to be replaced.

We have attached a guide to show you how to replace this sensor.

Awaiting your reply.

Sincerely,

Magnets are ok
Bonnet’s pins and base pins are looking good but anti-pinch pins are a bit corroded.
How can we send you thé pictures?
The robot is now sometimes not stopping on the start position but halfway: can we send you the video?

Hello @BaertBenedikte,

Thank you for your reply.

In this case, you will need a new hall-effect sensor and a new set of Anti-Pinch pins so we will send them to you under the warranty.

Please provide us with the following:

1- Shipping address.
2- Phone number.
3- Serial number located on the back of the robot.

You can send these details through a private message for more security.

Awaiting your reply.

Sincerely,
