The following troubleshooting should resolve the blue light blinking while the waste drawer is empty. Once resolved, the unit should consistently recognize when your cat visits and cycle accordingly.
To troubleshoot the blue blinking:
- Remove the drawer from the unit and press RESET.
- If the unit goes to solid blue, press the CYCLE button.
- The unit should start its cleaning cycle and goes back to solid blue.
If it did, the issue must be caused by the drawer liner not being properly tucked into the tabs.

If the blue light is still blinking, check your DFI for any obstructions:
- Turn off the unit and Unplug the power from the base
- Remove the Bonnet and the Globe
- Inspect the top of the Base where the Globe usually rests. Are there any debris? Small amounts of litter is normal. Clean as needed.
- Inside the waste opening there are two clear ““Lenses”” (left and right side). Ensure there are no debris on the Lenses. Sometimes litter can fall/splash onto them. ** To clean the lenses, we recommend wiping them off with a soft damp cloth and/or glass cleaner. Do not directly spray the Base or DFI Lenses. **
- There is a circuit board on one side behind the lens. There is hole in the lens in front of the laser head. Clean laser head gently with a q-tip.
- Replace the Globe and Bonnet. Reset the black key in the back of the unit into the pocket.
- Plug the unit back in. If you turned the power off, you will need to power it on and press ““cycle””.
Once the cleaning cycle is complete, the unit should be at the Home position with a Solid Blue LED on.
If the issue has not yet been fixed, then we would need you to re-calibrate the DFI laser.
To do so:
- Remove drawer
- Place hand just left of center and all the way up until it is hitting the globe
- Press and hold reset button until it flashes 3x, then release.
