Power Supply Issues

Certain specifications need to be met when it comes to the adapter needed to use the Litter Robot 3. These specifications are that it is a 15VDC regulated adapter 400mA to 1000mA. If the adapter does not meet these specifications, it could be the reason behind the error message and flashing lights.

You want to make sure that the power cord is not damaged, and it is a good idea to check to see if the extension cord you may have it plugged into, if you have it plugged into an extension cord, may be causing the issue, so you may want to try plugging your Litter Robot 3 into a wall outlet to see if it causes the blinking lights to stop.

Excess Weight In The Unit

It is a good idea to check if any excess weight is in your Litter Robot 3. Any excess weight inside the machine can cause for the motor to slow down. This can cause for the unit to be unable to complete a cycle in the allotted timeframe.

This excess weight could be due to the amount of litter inside the Litter Robot 3. Removing any excess litter from the unit should be able to solve the issue.

Bonnet Seated Improperly

If the bonnet is seated improperly, the Litter Robot 3 will start and stop during a cycle. You are able to properly seat the bonnet in order to prevent this from happening.

The first step to properly seating the bonnet is to disconnect the bonnet. Next, you want to gently flex the two front bonnet tabs outward. You want to flex them to as close to a 90 degree angle as possible and hold this position for approximately 20 to 30 seconds as this will remold the tabs.

Then, you can reattach the bonnet. There are two curved tabs in the back which can be tucked into the slots in the base. If you allow for these tabs to be left sticking out, the unit will be unable to cycle properly. Finally, you should feel as secure snap and hear a solid click.

Motor Obstruction

An obstruction or jam in the motor can cause for the three lights to start flashing as an error message. If there is an obstruction or jam in the motor, you can reset the unit in an attempt to fix the issue. Below are the steps to fix this issue.

  • Turn off the power and unplug the supply power from the base.
  • Remove both the bonnet and globe
  • Check the motor and clear any obstruction there may be
  • Reassemble the Litter Robot and check the litter level
  • Plug the unit back in and observe the first cycle of the unit to check if the steps worked

Internal Shield/Key Improperly Set

Cycling issues can occur if the internal shield or key is improperly set. If necessary, you can find videos online that instruct you on how to reset the internal shield and key in order to fix this issue. There is also the option of removing the internal shield. You can find instructions online to complete this process.

Globe Lift

The three flashing lights could be caused by the magnets in the globe skipping the position sensor. This happens when the globe encounters some type of resistance that causes it to lift out of its position during the cycle. This causes friction between the plastic globe and the base. Wiping the track at the base of the globe with furniture polish should help to solve this issue.
