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.

Place on its backPlace on its back

Lift the litter box on its end and press the manual rake button. If the rake engages in this position, put the box back down and move to the next step. If the rake does not engage, spray the rake tracks with canned air to remove any litter that may be caught inside, then put the box back down.

Wash litter box frameWash litter box frame

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. 

If the issue remains unresolved, proceed to the next troubleshooting section.

If you cannot remove the rake because it is still stuck out of the home position, put a slight amount of pressure on the rake to see if it has disengaged from the track. If so, you may need to remove the rake from the bottom of the litter box. To do this:

  1. Lift the box from the litter tray.
  2. Gently pull the sides of the inside of the litter box until you can work the rake out of the box.
  3. Once removed, put the box back down over the litter tray and reinsert the rake with the horizontal bar facing the back of the box.
  4. Make sure to lock the rake into place.
