My PetSafe® ScoopFree® Clumping Self-Cleaning Litter Box Has a Blinking Blue Light

Blinking Blue Light

If your litter box has a blinking blue light, this indicates the rake timer is counting down, or raking is currently in progress. After your cat leaves the box, it is normal to see the blue light blinking. This is signaling the 10-minute countdown has begun. It will continue to blink throughout the rake cycle.

If your cat enters the litter box while the rake is going, the rake will stop and not start again until after the cat exits.

Rapid Blinking Blue Light

If the blue light is rapidly flashing, this is signaling the button was pressed during the rake cycle causing it to pause. To resume, press and release the button.

If you didn’t press the button, or no cat has entered the litter box, and the rake is still not moving, try the troubleshooting steps below. 

Press the manual rake button after each step to see if the issue has been resolved.

Unplug the litter box for 30 seconds and plug it back in.

Lift the litter box on its end and press the manual rake button.

Check that the litter is not piled up by the sensors and is level between the minimum and maximum lines. 

Clean all six sensors(three on each side) with rubbing alcohol and a cotton swab even if the sensors appear clean. A film can develop over the sensors causing the litter box to react as if there is something inside the litter box.
