Blue and yellow light both permanently on

I have had the litter robot for around 3 weeks. The blue and yellow light are both permanently on. Also I have noticed it doesn’t always automatically cycle
Once a cat has been in. Yesterday I came home to find the robot full of waste and no cycle had taken place.
All my cats are around 10lbs or more

Hi,

I think your Litter-Robot is in the 8-hours sleep mode.
